IntroductionThis is our CVS commit log in chronological order, latest first, for the entire source tree. Thisshows the evolution of our entire system, from beginning to end. It shows approximately whoworked on what areas, and how much time was put into each section.

It should be noted that the username associated with a commit does not necessarily indicatethat user solely worked on it, as collaborative work did regularly take place. However, ingeneral it is a good representation of who did what and why.

CVS LogsEach commit has an associated log message which usually indicates the purpose of achange. Further details of problems or solutions are often included.

March 2001

2001-03-27 Tuesday 09:46 pjm2 <[email protected]>

* host/ihost/README (1.2): Added a reference to the maintenancedocumentation.

2001-03-27 Tuesday 01:05 ab11 <[email protected]>

* host/c/: Host.cpp (1.5), Config.cpp (1.6), Config.h (1.6):Cleaned up code and modified one or two bits


* host/c/: SubPipe.cpp (1.2), SubNet.cpp (1.4), SubNet.h (1.2),SmallNet.cpp (1.5), SmallNet.h (1.5): tidied up


* host/c/: SysMon.cpp (1.8), SysMon.h (1.4): tidied up and removeddead code.


* host/c/XMLFormatter.cpp (1.7): tidied up and fixed a few rangecheck errors

2001-03-26 Monday 22:48 tdb1 <[email protected]>

* client/conient/Config2.inc (1.10), client/conient/Makefile (1.7),corbaservices/Config2.inc (1.5), corbaservices/Makefile (1.4),reports/DBReporter/Config2.inc (1.3), reports/DBReporter/Makefile(1.4): Our logo is now on the javadoc pages.


* server/: Config2.inc (1.20), Makefile (1.22): Now have thei-scream logo on the javadoc pages.


* reports/DBReporter/Config2.inc (1.2): Got the module name wrong;)


* reports/DBReporter/build/lib/README (1.1): Ensures this directoryis correctly created.


* reports/DBReporter/build/: run.bat (1.1), run.sh (1.1): For easyrunning.


* reports/DBReporter/build/Makefile (1.1): Part of the new Makefilestructure.


* reports/DBReporter/: Config2.inc (1.1), Makefile (1.3),Makefile.inc (1.1), configure (1.1): New Makefile setup. Similar tothe other Makefiles in i-scream, although it is a touch muddled bythe lack of a package hierarchy. This is not a problem, and itshould "appear" the same to external scripts.


4


* reports/DBReporter/DBReporter.properties (1.2): report_list.txt-> reportlist.conf


* reports/: Config2.inc (1.8), configure (1.3): No longer needed,Makefile functionality moved into DBReporter.


* reports/Makefile (1.3): Reduced in size, only bare minimum leftfor compatibility.


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.19): The "checking" part had moved from the main class to aninner class, thus the synchronize(this) blocks were pointing atdifferent "this"'s. This how now been fixed, we hope.


* server/uk/org/iscream/util/Queue.java (1.20): Some furtherchecking to solve deadlock issues. Firstly when checking if thequeue is "full", we now do a check for "greater than or equal" tothe limit, rather than just "equal". If for any reason it does getover the limit, it'll still get caught. Secondly we no longercheck if the queue is of size 0 to do the notify, we just do itanyway. We figure this is probably more efficient than trying to doa massive synchronization block.


* reports/php/build/README (1.1): Need to put this file here tomake the directory exist. Annoying I know ;)


* reports/php/: Config.inc (1.1), Makefile (1.1): Build scripts. Inessence, these just package up the php pages into a single archiveready for distribution.


* host/ihost/Makefile (1.4): Slightly better cleanup.


* server/uk/org/iscream/util/FormatName.java (1.11): We shouldn'thardcode the Locale like that.


* server/uk/org/iscream/componentmanager/ConfigurationProxy.java(1.14): Closing the javadoc tag helps...

2001-03-26 Monday 02:39 ajm4 <[email protected]>

* server/uk/org/iscream/componentmanager/: ConfigurationCache.java(1.4), ConfigurationProxy.java (1.13): Now javadoc'd.

2001-03-24 Saturday 20:19 ajm4 <[email protected]>

2001-03-24 Saturday 18:43 tdb1 <[email protected]>

* server/uk/org/iscream/client/alerters/IRC__Alerter.java (1.27):Opps, mistake in that last commit.


* server/uk/org/iscream/client/alerters/IRC__Alerter.java (1.26):"last alert" will now display the last alert received... not thelast one sent. This means that alerts sent whilst in "stop alerts"mode will be included.

2001-03-23 Friday 23:55 pjm2 <[email protected]>

* reports/php/latest/latest_display.inc.php (1.10): Changed thetitle of the uptime field.

* reports/php/README (1.1): A simple readme doc for the i-screamweb interface.

2001-03-23 Friday 19:12 tdb1 <[email protected]>

* server/uk/org/iscream/client/AlerterManager.java (1.8): We weregrabbing a queue and then not actually using it. Thus the queuejust built up and overflowed. Opps.


* client/conient/splash/: i-scream-splash.bmp (1.2),i-scream-splash.gif (1.2), i-scream-splash.jpg (1.2): All imageshave had their copyright notices modified, also including thei-scream website URL.

* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.11):We were naming the queue ".queueN" rather than "queueN". This isbecause substring is inclusive on the first character :)


6


* reports/php/public/public.php (1.7): Altered the captions by therefresh options


* reports/php/public/public.php (1.6): Added the options to setmeta refresh intervals and scroll rates (the latter is for IE4.0+only)


* reports/php/index/index.php (1.16): Reflects changes made to theautoscroll settings - i.e. a value is specified for the scroolrate, rather than using a fixed value.


* reports/php/shared/title.inc.php (1.13): The scroll speed can nowbe set. $scroll may be set in the querystring to a value of 1 to 9inclusive, which is the number of pixels scrolled every 1/20th of asecond.

2001-03-23 Friday 16:57 ab11 <[email protected]>

* host/c/SysMon.cpp (1.7): fixed silly logical error in 'specialcase' with end of attributes


* host/c/SysMon.cpp (1.6): now puts attributes in "" to conform tocorrect xml


* host/c/XMLFormatter.cpp (1.6): added in the closing tags on anattribute again


* host/c/SysMon.cpp (1.5): Tidied up the debug level so it is moreinformative.


* host/c/SysMon.cpp (1.4): Quick bugfix to fix parsing fromstatgrab and segmentation faults


* host/c/SysMon.h (1.3): Added in a constant value maxTitles whichspecifies the maximum number of things it expects to get fromstatgrab.


* host/c/SubNet.cpp (1.3): Un hard coded the UDP destination andport.


* host/c/Host.cpp (1.4): Modified the timing loop so it no longercollects data while it is not needed. This can be un commented whenany averager system is used.

* host/c/XMLFormatter.cpp (1.5): put in some error checking to stoppossible segmentation faults


* server/uk/org/iscream/rootfilter/RootFilter.java (1.37): Opps...if both were null it would try and start them :)


* server/uk/org/iscream/rootfilter/RootFilter.java (1.36): Arg..more bugs. Need to check both independently.


* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.10):Bah... Register does config lookups too.


* server/uk/org/iscream/dbinterface/DBInterface.java (1.13): Sortedout the naming a bit. Uses the config name "DBInterface", with theNAME now coming from DBInterface.name, rather than RootFilter... asbefore.


* server/uk/org/iscream/clientinterface/ClientInterfaceMain.java(1.24): Sorted out the naming a bit. Uses the config name"ClientInterface", with the NAME now coming fromClientInterface.name, rather than RootFilter... as before.


* server/build/etc/system.conf (1.52): Tidied ClientInterface andDBInterface sections.


* server/uk/org/iscream/rootfilter/RootFilter.java (1.35): Now onlyenforces a dependency on either the Client Interface or theDatabase Interface if it is configured. This ensures that thestartup order is still correct (which it wouldn't if the checkswere removed), but also doesn't enforce the checks when one of theinterfaces is disabled.


* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.9):Arg... what are we doing sending a hashcode as a config name !? Itnow sends _name (which is Queue unfortunately) as the configname... and the property as before.


* server/build/etc/default.properties (1.13): Opps... this a'intright :)

2001-03-23 Friday 04:05 ajm4 <[email protected]>

* client/conient/uk/org/iscream/conient/: ConnectionHandler.java(1.31), DataReader.java (1.13): Now only disconnects the data linkon a data communication failure.


* client/conient/uk/org/iscream/conient/: ConfigurationDialog.java

(1.13), ConnectionHandler.java (1.30), DataReader.java (1.12):DataReader can now shutdown the links if it detects a read error

More tidying in the ConfigDialog...all done now.


* client/conient/uk/org/iscream/conient/ConfigurationDialog.java(1.12): tidied up much more.


* client/conient/uk/org/iscream/conient/: ConfigurationDialog.java(1.11), DataPanel.java (1.25): Now sorts the host lists throughout.


* server/uk/org/iscream/client/AlerterSkeleton.java (1.6): Opps...we were going round and round in circles. AlerterManager and anAlerter both needed to reference each other whilst beingconstructed... now that's not going to work :)


* server/uk/org/iscream/client/monitors/: CPU__Monitor.java (1.23),Disk__Monitor.java (1.8), Heartbeat__Monitor.java (1.18),Load__Monitor.java (1.3), Memory__Monitor.java (1.7),Process__Monitor.java (1.3), Queue__Monitor.java (1.8),Services__Monitor.java (1.4), Swap__Monitor.java (1.6),UserCount__Monitor.java (1.2): Fully javadoc'd all the monitors.Also made a few little changes here and there, removing code thathad been duplicated by copying other monitors, and tidying up anysilly little things (such has hardcoded integer values).


* server/build/etc/system.conf (1.51): Added UserCount monitor tothe list.


* server/uk/org/iscream/client/: Alert.java (1.15),AlerterManager.java (1.7), AlerterSkeleton.java (1.5),ClientMain.java (1.19), ClientServant.java (1.9),MonitorManager.java (1.13), PluginAlerter.java (1.5),PluginMonitor.java (1.5): Javadoc'd the whole bally lot.


* server/uk/org/iscream/client/: monitors/WebFeeder__Monitor.java(1.6), alerters/WebFeeder__Alerter.java (1.7): Changed the way themonitor and alerter parts of the WebFeeder work. They now only geta reference to WebFeeder if they are active. This stops theWebFeeder being instansiated (which clears out Alerts and otherstuff) if it's not actually been turned on.


* server/uk/org/iscream/client/: AlerterSkeleton.java (1.4),MonitorSkeleton.java (1.11): Lots of commenting to explain theiruse.


* server/: build/etc/system.conf (1.50),uk/org/iscream/client/monitors/Makefile (1.10),uk/org/iscream/client/monitors/UserCount__Monitor.java (1.1): Addednew UserCount monitor. This one fires an alert if too many users

* server/uk/org/iscream/client/alerters/: EMail__Alerter.java(1.22), IRC__Alerter.java (1.25), WebFeeder__Alerter.java (1.6):All skeletorized and javadoc'd now.


* server/uk/org/iscream/client/AlerterSkeleton.java (1.3): Added acouple more vars that are global to alerters. Finished javadoc.


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.17): Fixed inheritance bug.


* server/uk/org/iscream/client/WebFeeder.java (1.18): Now does acleanup of stale alerts left behind by a host after it shuts down.This is done by removing any alerts older than a FINAL Heartbeatalert.


* server/uk/org/iscream/client/: AlerterManager.java (1.6),AlerterSkeleton.java (1.2), alerters/EMail__Alerter.java (1.21):General tidy up, and small fixes.

2001-03-22 Thursday 23:35 ajm4 <[email protected]>

* server/uk/org/iscream/client/alerters/EMail__Alerter.java (1.20):Now implemented a skeleton Alerter to allow easier creation of newAlerters.

Email alerter now implements this.


* server/uk/org/iscream/client/: AlerterSkeleton.java (1.1),Makefile (1.12), MonitorSkeleton.java (1.10): Now implemented askeleton Alerter to allow easier creation of new Alerters.

2001-03-22 Thursday 23:09 pjm2 <[email protected]>

* reports/DBReporter/DatabaseRemover.java (1.3): Added REVISION forthe class.


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.16): Re-arranged...better layout.


* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.7):Now sends a nicer alert identifier, passes the queue number thatrasied the alert.


* reports/DBReporter/ChartDataWriter.java (1.7): Minor changes

2001-03-22 Thursday 22:29 tdb1 <[email protected]>

* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java


10

(1.15): For some reason this code wouldn't compile under FreeBSDwithout this change.


* server/uk/org/iscream/client/alerters/: EMail__Alerter.java(1.19), IRC__Alerter.java (1.24), WebFeeder__Alerter.java (1.5):Rejigged to use the same queuing structure as the Monitors.

Changed all the alerters to use new structire.

Possibly need to create an alerter skeleton...


* server/uk/org/iscream/client/: AlerterManager.java (1.5),PluginAlerter.java (1.4): Rejigged to use the same queuingstructure as the Monitors.


* server/uk/org/iscream/dbinterface/: DBInserter.java (1.25),DBInterface.java (1.12), DBServant.java (1.1), Makefile (1.6),XMLPacketWrapper.java (1.1): Changed the overall structure of theDBInterface. The reason for this was that timestamping of packetsas they were added to the database was not correct. If the databasewas running slow, and data was held up, it would receive the timestamp at insertion, not at receipt. This is changed by creating anXMLPacketWrapper object on receipt, containing the timestamp ofarrival at the DBInterface - this should be consistent regardlessof where the XML originated. The XMLPacketWrapper objects are thenqueued up for processing by the inserter, which can do so at it'sown pace - without affecting the time stamps in the database. Thiswill allievate problems that have arised in the graphs when thereports are run - namely "blips" where the data hasn't beeninserted quick enough.


* reports/DBReporter/SHTMLWriter.java (1.2): Javadoc'd thewritefile method.


* TemplateClass.java (1.11): Forgot to change the package in thisclass.


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.14): Now works with the new queue structure.


* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.6):A more meaningful name.


* server/uk/org/iscream/componentmanager/ConfigurationProxy.java(1.12): When we look for something that's not actually there, weneed to remember that fact. If we don't, it will keep checking,rather than caching null.


* reports/php/public/public.php (1.5): Made some default selectionsfor the user.

* reports/php/alerts/alerts.php (1.32): Some of the changes to thesmall report affected the larger reports. A vdiff shows thesechanges nicely.


* reports/php/alerts/alerts.php (1.31): It seemed like a good ideato put a little space between each machine.


* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.5):Opps... the hashcode as a source isn't helpful :)


* reports/php/shared/title.inc.php (1.12): Minor change


* reports/php/alerts/alerts.php (1.30): Fixed the "many reports onone line" problem.


* server/uk/org/iscream/client/MonitorSkeleton.java (1.9): nowdebug outputs the queue number a monitor is assigned


* reports/php/shared/title.inc.php (1.11): Altered the javascriptin the title.inc.php header include. A page now automaticallyrefreshes when it has finished scrolling to the end of the page.If the page is 100% visible without scrolling, then there is a tensecond delay before the page is refreshed.


* server/uk/org/iscream/client/: MonitorSkeleton.java (1.8),monitors/WebFeeder__Monitor.java (1.5): now correctly process datafrom the inbound queue


* server/uk/org/iscream/util/Queue.java (1.19): These might bebetter synchronized :)


* reports/php/index/index.php (1.15): Added a link to the "buildyer own" page.


* server/uk/org/iscream/client/ClientMain.java (1.18): Forgot tochange the Queue names.


* reports/php/alerts/alerts.php (1.29): The 'small' version of thealerts are now centered on the page. This looks slightly cleanerwhen the page width is set to 100% by the user.

* reports/php/public/public.php (1.4): The form now allows users tosubmit their preferences. Descriptions of each field can be foundto the right of the input areas.


* server/uk/org/iscream/: client/MonitorManager.java (1.12),client/WebFeeder.java (1.17),componentmanager/ConfigurationProxy.java (1.11),componentmanager/ReferenceManager.java (1.15): Need to set these tobe synchronized, otherwise two Threads could potentially call thegetInstance() method at the same time - resulting in twoconstructions.


* reports/php/public/public.php (1.3): This page now lets peoplechoose from the various options (hide user input form, set fontsize, page width, machine list, auto scroll, etc) to give acustomisable display of alert data


* server/uk/org/iscream/client/: MonitorManager.java (1.11),MonitorSkeleton.java (1.7), monitors/CPU__Monitor.java (1.22),monitors/Disk__Monitor.java (1.7), monitors/Load__Monitor.java(1.2), monitors/Memory__Monitor.java (1.6),monitors/Process__Monitor.java (1.2), monitors/Queue__Monitor.java(1.4), monitors/Services__Monitor.java (1.3),monitors/Swap__Monitor.java (1.5), monitors/WebFeeder__Monitor.java(1.4): Modified to use the new style queuing in the local client

creating an alerts display that is suitable for use in a publicterminal, i.e. at a helpdesk.


* server/build/etc/system.conf (1.49): Changed the Queue thresholdsto something more realistic.


* server/uk/org/iscream/client/monitors/Queue__Monitor.java (1.3):Some major bugs in here meaning it would never actually look atqueueStat the queueStat packets!


* server/uk/org/iscream/client/: ClientMain.java (1.17),MonitorManager.java (1.9), PluginMonitor.java (1.4): Radicallychanged the way data is passed around. Monitor's are now requiredto get data from the MonitorManager queue's, rather than beingpassed it. This allows them to run in parallel, rather than theserial setup we had before.


* reports/php/shared/title.inc.php (1.9): Modified the titleinclude


* reports/php/alerts/alerts.php (1.26): Modified the 'small'version of the alerts such that they may have the font size altered(via the title.inc.php include value of $fontsize). This is handyfor public display applications.


* reports/php/index/index.php (1.13): Added a note that thescrolling reports only work in IE4.0+


* reports/php/index/index.php (1.12): Added one of theauto-scrolling reports to the list.


* reports/php/shared/title.inc.php (1.8): Font size may bespecified in the title include (as &fontsize=n). This may be usedby any pages that use the title include.


* reports/php/shared/title.inc.php (1.7): Supported browsers maynow add &scroll=true to the querystring to have a page thatautomatically scrolls and refreshes when it reaches the bottom ofthe page. This would be ideal for helpdesk-style displays wherethe font size must be very large and hence the data does not allfit onto one screen. (At last, something useful that javascriptdoes!)


* reports/php/shared/: bottom.inc (1.7), level1.gif (1.3),level2.gif (1.3), level3.gif (1.3), level4.gif (1.3), level5.gif(1.3): Now using the i-scream.org.uk email addresses at the bottomof the page. Also changed all of the level gifs so that there wasa more distinct difference between the colour of the blue squares.

* reports/php/index/index.php (1.11): Altered the descriptions ofthe two "Helpdesk-style" reports.


* host/winhost/: nettest.vbw (1.15), winhost_install.exe (1.6):Latest installer for the winhost.


* host/winhost/winhost.exe (1.9): Latest build


* host/winhost/nettest.frm (1.39): Winhost may now be correctlyreconfigured at all times that a heartbeat is not occuring.


* host/ihost/ihost.pl (1.34): If, during a heartbeat, the hostreceives an ERROR response from sending the last_modified time ofits configuration, the host is expected to reconfigure itself. Ifthe configuration changes many times in a short period of time,many heartbeats may be lost if they bail out as soon as the ERRORresponse is received. This has now been changed so that aheartbeat is completed in its entirety before the host attempts toreconfigure with the filter manager.


* server/build/etc/system.conf (1.48): Slightly longer heartbeattimeout.


* server/build/etc/system.conf (1.47): Tidied up the Monitor'ssection. Alert timeouts are stored as defaults, which can beoverridden. This saves repeating the same values. Also neatenedthe layout and comments. More detailed explanation could be givenin the user documentation.


* server/uk/org/iscream/client/Register.java (1.16): Now allows theuse of a default timeout value for all Monitors


* server/build/etc/system.conf (1.46): Added new Queue monitor.

* reports/php/alerts/alerts.php (1.25): Added "Upper" and "Lower"comments in threshold levels. Or, for those that are neither,"Normal" is shown by the threshold value.


* reports/php/latest/latest.php (1.35): Some browsers do notcorrectly render images if their size is set to zero. If one ofthe graph bar images has a zero width, then it will be set to 1.


* reports/php/historical/browser.php (1.40): Historical reports nowhave a link to the alerts associated with them.


* reports/php/alerts/alerts.php (1.24): Small versions of thealerts now link to large versions of the alerts for that individualmachine. These large ones then provide links to the latest datapages.


* reports/php/alerts/alerts.php (1.23): Fixed the alignment ofthreshold and alert values


* reports/php/shared/: level1.gif (1.2), level2.gif (1.2),level3.gif (1.2), level4.gif (1.2), level5.gif (1.2): Why werethese not blue in the first place?!?!?!


* reports/php/alerts/alerts.php (1.22): Graph of alert level is inthe top left of each report area, with the title on the top right.The values associated with the report are now centered in thetable.


* reports/php/alerts/alerts.php (1.21): Alerts level scales addedto the large view. Also made sure that empty machine directoriesare ignored.

* reports/php/alerts/: alerts.php (1.20), alerts_config.inc.php(1.13): Added level graphs to the small reports pages. These workquite nicely!


* reports/php/shared/: level0.gif (1.1), level1.gif (1.1),level2.gif (1.1), level3.gif (1.1), level4.gif (1.1), level5.gif(1.1): These are lots of little jubbly images for giving a visualindication of an alert level for alerts.


* reports/php/alerts/alerts.php (1.19): Made the fonts bigger,hence easier to read from afar

* host/generic/statgrab.pl (1.43): "brackets are the most evilthing in the world" - pjm2


* reports/php/index/index.php (1.10): Now with super dooper linksto two demonstration pages. The first demo page is the sort ofthing that would be displayed at computing service helpdesk (orsimiliar sort of place) and it shows the current status of raptor,which is automatically updated every 10 seconds. The second pageshows a condensed list of all machine and is also updated every 10seconds. Both demos have the selection form hidden.


* reports/php/alerts/alerts.php (1.17): Sorted out the table layoutand indenting issues.


* reports/php/alerts/alerts.php (1.16): Small versions of thereports now also have the alert level shown, and also in theapproprite colour


* reports/php/alerts/alerts.php (1.15): Each machine name appearsunder a smaller heading when viewed in small mode


* reports/php/alerts/alerts.php (1.14): Different tablearrangements are shown on individual and "all" reports if&small=true is in the query string


* reports/php/alerts/alerts.php (1.13): If an attribute called"small" is specified on the query string, the reports are notshown.



18

* reports/php/alerts/alerts.php (1.12): When the list of ALLreports is being viewed, we now no longer try to go through thedirectory listing if it is empty (as this causes an error messageto be echoed to the client)


* host/generic/statgrab.pl (1.42): statgrab should now return thecorrect values for swap and memory, i.e. not swapped round as aresult of the regexping of the reversed top output. Each line mustbegin with either Mem: or Swap: and a non-greedy match is made ofall characters before the bit of data we're interested in, so itshould read the correct numbers each time.


* reports/php/shared/: title.inc (1.8), title.inc.php (1.6): Metahttp equiv refresh tag may be added if $refresh is defined as aninteger between 0 and 999. This means that people can append"refresh=n" to the end of a URL to get the page to automaticallyrefresh every n seconds. This is suitable for "helpdesk style"displays of system information on a dumb machine.

* host/generic/statgrab.pl (1.41): statgrab now gets the Linux CPUtimes correctly. This was done by runing top for 2 iterations, andreversing the output. This allowed the correct times to be grabbed.Bodge city :P Also got "nice" cpu time on Linux, and add it to usercpu time. Same as was earlier done on FreeBSD.


* host/ihost/ihost.pl (1.33): Increased the TCP config wait timebetween retries to one minute. Fixed sparodic errors withobtaining the I.P. address that caused a host to go all wibblyafter a few days.


* host/generic/statgrab.pl (1.40): Fixed the >1000 processes bug.It now doesn't care about a space, and makes sure what it'sgrabbing is a number.


* host/generic/statgrab.pl (1.39): Now finally gets RAM total. Alsouses a new command to get RAM free, and the load values. Anythingother than parsing top really :)


* server/uk/org/iscream/client/WebFeeder.java (1.16): Now cleans upempty host directories on the alert pages.


* server/build/etc/: computing.conf (1.4), default.properties(1.12), rocks.conf (1.4), system.conf (1.42): More general changesto the configuration.

This now means that data for memory/swap/disks/services are allcorrectly updated on the display the first time they get data.Rather than before, when they had to have at least two packets togain all the data and would be slightly wrong.

Now it is all fine and dandy...



24

* reports/php/latest/latest.php (1.34): Put the mount point of diskgraphs on the next line, as if these are too long, it causes thegraph to be stretched.


* server/uk/org/iscream/client/monitors/: Disk__Monitor.java (1.4),Memory__Monitor.java (1.5): added the option:

Monitor.Disk.thresholdMeasure=VALUE/PERCENTAGEMonitor.Memory.thresholdMeasure=VALUE/PERCENTAGE

* reports/php/shared/title.inc.php (1.4): Lightened the timestampand used 12-hour time format.


* reports/php/index/index.php (1.8): Used the other title include -title.inc.php - as it has a timestamp in it.

* reports/php/shared/title.inc.php (1.2): Added the current dateand time is a human-readable format to the include file. Everypage that uses this include will now have the current time stampedat the top of it.


* reports/php/shared/title.inc.php (1.1): A different version ofthe title include. This one has a .php file extension so that itmay include PHP script, such as displaying the time at which thepage was generated - this seems like an extremely important anduseful thing to have on a page that claims to provide realtimeinformation!


* reports/DBReporter/DBReporter.properties (1.1): Settings file forthe DBReporter. This allows the 'user' to easily change the mostimportant settings, such as which days to produce the reports for,which days to delete (if any) and the database connection details(and output destination)


26


* reports/DBReporter/DBReporterSettings.java (1.1): Classresponsible for obtaining the settings from a properties file, andensuring that there are appropriate entries for each value; TheobtainSettings method returns false if it is unable to get all thedata it requires. As there are only a few settings stored in theclass, we've provided simple accessors to get at them, rather thanproviding direct access to the contents of the Properties object.


* reports/Config2.inc (1.6): Using crimson instead of parser.jarfor the XML parsing.


* reports/configure (1.2): The configure script obtains crimson.jarinstead of parser.jar for the XML parsing.


* reports/Config2.inc (1.5): Stupid


* reports/Config2.inc (1.4): Put in the full path to the settingsfile in the config.


* reports/DBReporter/DBReporterMain.java (1.31): Forgot to obtainthe settings from the file before we used them ;)


* reports/Config2.inc (1.3): Updated the configuration so that thesettings file location is specified, and the output directory andreport list location have been removed.


* reports/: Config2.inc (1.2), Makefile (1.2): Altered the Makefileso that only the settings file is given as a command line parameterto the DBReporterMain


* reports/DBReporter/: DBReporter.java (1.26), DBReporterMain.java(1.30), DatabaseRemover.java (1.2), ReportMaker.java (1.6): Changedthe name of the package used for the XML parsing. Catches theInvalidXMLException and tries to move on to the next row withoutdoing anything. All settings are obtained from a settings filenow. The location of the settings file must be specified as theonly argument when running the program. The settings file alsocontains the connection string for the database and the name of thedriver to be used, so it should always be possible to make just afew changes to use a RDMS other than MySQL if we really want to.


* server/uk/org/iscream/componentmanager/ComponentManager.java(1.35): Slightly more accurate output.

* server/uk/org/iscream/clientinterface/:CorbaControlHandlerServant.java (1.11), CorbaDataHandler.java(1.7): When a CORBA Client disconnects it is caught in theDataHandler. But this would leave the ControlHandler just lurkingabout, so we now explicitly make an effort to close it down, anddisconnect it from the ORB.


* server/uk/org/iscream/util/XMLStringParser.java (1.12): Furtherdrive for efficiency. Now uses a LinkedList with an Iterator, overan ArrayList. This should work better as we're only reallyiterating over it from beginning to end. Also removed theindentLevel, because although it seemed to be sensible.. it didn'tactually get used anywhere.


* server/uk/org/iscream/util/XMLPacketMaker.java (1.15): Using astatic reference to the parser factory was probably not the best ofideas. We had problems when everything was in one JVM, which couldbe explained by the static reference.

* host/c/socket++-1.10/sockstream.C (1.2): fixed the "UDP size nogreater than 1024 bytes" with hard coding. The error is due to thedefinition within /usr/include/iso/stdio_iso.h which makes me thinkthat perhaps we are breaking the normal UDP rules with anythingabove 1024. Currently fixed the buffer size to 8192 (currentpackets run in at about 2.5 - 3k in size so we have 'some' futureproofing.. This is very much something that needs to be discussed.


* server/uk/org/iscream/client/MonitorManager.java (1.7): A smallchange to make the code more proper in creation of strings.


* server/uk/org/iscream/componentmanager/ReferenceManager.java(1.14): Just a safty check. The _instance is now initialised to benull.

* reports/php/alerts/: alerts.php (1.6), alerts_config.inc.php(1.9): Altered the colour for the "Notice" alerts. Got rid of someof the redundant diplay information. After testing it out, itseems to work okay, but if there's time, it might be worth sortingthe list in alert level order.


* reports/php/alerts/: alerts.php (1.5), alerts_config.inc.php(1.8): Added alert level colours and altered the layout so it makesa bit more sense for service checks.


* server/uk/org/iscream/filter/FilterServant.java (1.17): Fixed along standing problem with the Filter not returning it's own hostaddress (fqdn) on windows machines. It's a bit of a workaround, butat least it works :)

* host/ihost/ihost.pl (1.31): Just changed the expression withinthe connection while loop.


* host/ihost/ihost.pl (1.30): If we cannot connect to the filtermanager, then we shall retry without closing the socket, as itwon't be open to close ;)


* server/uk/org/iscream/client/WebFeeder.java (1.10): Now properlycleans up files, and fixed the filename extension.


* server/uk/org/iscream/client/alerters/IRC__Alerter.java (1.21): Aquick little change so that it won't try and join a channel it'salready in.

* server/uk/org/iscream/client/WebFeeder.java (1.9): Addedfunctionality to the constructor to tidy up any existing alertsfrom any previous invocations of the server. Also changed theroutine that dumps the data to rename an old file, rather thandelete and recreate a new one.


* server/uk/org/iscream/client/WebFeeder.java (1.8): Now dumps datain a "correct" format. Still needed is cleaning up, both onstartup and after a given interval.


* server/uk/org/iscream/client/Register.java (1.13): Now an OKalert will have an initialAlertTime that follows from the alert itis giving on OK for.

The oldmethod was to attempt to start a Component, and if it failed, itprobably had a depdency problem. The approach now is to ask theComponent to perform a dependency check first, then if thissuceeds, have a go at actually starting it up. The actualdependency check is a bit neater and more precise than before, andshould be much more fool proof. The order the components arespecified in the default.properties file is now irrelevant,although the "correct" order would certainly increase booting time.

* server/build/etc/system.conf (1.34): Added config for servicechecks


* server/uk/org/iscream/client/monitors/Services__Monitor.java(1.1): Initial checkin. This checks the services running on ahost.

It currently is maybe a bit of a hack, it uses the services statusvalue as the threshold, thus raising an alert for a non-zerostatus. This might be wrong and should be looked at.


* server/uk/org/iscream/client/: MonitorSkeleton.java (1.3),Register.java (1.11), monitors/CPU__Monitor.java (1.18),monitors/Disk__Monitor.java (1.2), monitors/Heartbeat__Monitor.java(1.12), monitors/Makefile (1.6), monitors/Memory__Monitor.java(1.3), monitors/Swap__Monitor.java (1.3): TOTALLY re-wrote theRegister class and made appropriate changes thoughout. It is nowmuch more obvious what is going on in many places.

The problem was probably caused by doing CPU as a first monitor andhard coding the number of attributes a Register stores. Now if amonitor wants to store multiple attributes, it has to do thatitself. This makes alot of things much more readable andinteligable as a result.


* server/build/etc/system.conf (1.33): Now has the config for thenew Disk monitor

They all do very similar things, soit seemed worth putting all the behaviour in one place. This alsohas another advantage, namely that service checks are now muchquicker to produce, and that in the future the checks could even bemoved to a general checker that reads from the configuration.

* server/uk/org/iscream/client/MonitorSkeleton.java (1.2): Opps,it's been in the wrong package all this time :)


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.11): A slight logic error. Should now properly count the timebetween heartbeats, and thus won't bypass thresholds when itshouldn't :)


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.10): The synchronization is causing delays. Looking at theanalysePacket method, it only modifies the HashMap structure when anew host appears - which isn't very often relatively. Therefore,only that section is synchronized, meaning the new packets thatarrive regularly will not have to wait for the "checking" thread.I'm hoping the logic behind the synchronization here works.


* server/uk/org/iscream/client/monitors/Heartbeat__Monitor.java(1.9): Added some synchronization. We managed to get aConcurrentModificationException in the server :)

Thismade the alerts all fire when they shouldn't. Also noticed thatsome "Infinity" items appeared, probably due to a divide by zerowhilst working out the percentage. It seems thatDouble.parseDouble() wasn't throwing NumberFormatException.. maybe:/ Finally, the numbers were appearing like 95.238172732123, whichlooks silly.

* reports/php/historical/browser.php (1.25): The chart data filename can also be specified within the configuration. The methodused to submit the form may als obe configured - at this currentmoment in time, this should only really be set to either "POST" or"GET". GET sends the form with the parameters specified in thequery string (at the end of the URL). POST sends them over HTTPwithout being displayed in the URL. We shall stay with the GETmethod for now - although it produces rather ugly, long URLs in thebrowser, they are on the other hand quite handy because you canthen copy it and email the URL to somebody to show them areparticular chart and say something like, "ooh, what happened toraptor there?"

* reports/php/historical/browser.php (1.19): Colour of separatorlines may now be configured. This works only in newer browsers,however, the colour is not crucial to the operation of the reportsand they thus work (and look) fine even in Netscape 3.


* reports/php/historical/browser.php (1.18): A customised scale maynow be included by altering the $scaleImage attribute.


* reports/php/historical/browser.php (1.17): Can now change asingle setting to move the reports directory.

Every access to the lists and hostmap issynchronized on this object. This means that only one of the bitsmay be executed at once. Whilst this may clearly solve someproblems, it does open this class to becoming a major bottleneck,and could possibly lead to deadlock externally (although I thinkour Queue's avoid this issue).

Full 1.1 support andconfiguration for it. Still a few configuration bugs to iron out,but all the major construction and implementation is done. Addeddebug messages to ConnectionHandler. Fixed bug in the datapanel.


* server/uk/org/iscream/util/Queue.java (1.15): A missed > resultedin naff XML, which resulted in null packets, which resulted in thewhole server crashing. This can't be right..... :)


* server/uk/org/iscream/util/Queue.java (1.14): Finally implementedmaximum size on Queue's. This is an optional feature, and is onlyused if the correct constructor is called.

For normal use (with no limit), just use the empty constructor;new Queue()

For using a limit, use the following constructor; new Queue(intmaxSize, int removeAlgorithm) Where; maxSize = the maximum sizeof a queue removeAlgorithm = Queue.RANDOM, Queue.FIRST,Queue.LAST, or Queue.DROP

Queue.RANDOM = Remove a RANDOM item from a full queue when adding.Queue.FIRST = Remove the FIRST item from a full queue when adding.Queue.LAST = Remove the LAST item from a full queue when adding.Queue.DROP = Don't remove, just drop the new item when adding.

PlotData.java (1.16), Report.java (1.21), ReportList.java (1.11):These classes now reflect the radical new design of the i-screamdatabase. Mulitple reports are now generated per machine per SQLselect, thus reducing the number of XMLPacket objects that need tobe made. This vastly reduces the execution time, as well asreducing the number of queries that need to be taken from thedatabase. Reports are placed in a directory structure ofdate/machine_name/report_name so that 3rd party interfaces may usethis data easily (as well as the PHP interface already provided bythe i-scream team).

The new design also meant that it was possible togenerate multiple reports per machine per SQL select, so otherparts of the DBReporter were rewritten to take advantage of thisperformance gain.

There is somedebugging code at the top, this allows each permutation to easilybe checked. This is not efficient, it needs to be reordered tomake the most common case come first.

As aresult of the classpath change in Config2.inc, the builddependencies are slightly altered. It is no longer required thatthe IDL files be in a compiled state prior to building the code...Java can still find them. In fact, Java will probably compile themitself with it's internal dependency checking :)

The old setup looked like this;

UDPReader ------> FilterThread (thread) --> (parent) TCPReader------> FilterThread (thread) --> (parent) FilterServant -->FilterThread (thread) --> (parent)

Seeing this from a threaded point of view, each time a packet camein (through whatever means - UDP, TCP or CORBA), a FilterThreadinstance was created to deal with it. If the link to the parent wasslow this resulting in a build-up of FilterThreads all waiting totalk to the parent - and there is only one actual parent object,with a synchronised thread, so they have to queue up anyway.

As a result of this, the following change has been made.

UDPReader -------\ TCPReader ----------> Queue (single) >--FilterThread --> (parent) FilterServant ---/

In this setup, each of the three objects that generate packets onlysee the single instance of a Queue. They all add their data to thisQueue, and then carry on with the task of listening. TheFilterThread (having it's role changed slightly) now acts as aconsumer of the Queue, in that it grabs data from the Queue anddeals with passing it on to the parent.

This setup should be more efficient in the long run, especiallyunder a high load situation. The only problem could be the Queuegrowing to an unlimited size, but this is a Queue design issue.

* server/uk/org/iscream/rootfilter/RootFilterServant.java (1.3):Had to add these if this servant is going to appear to be a Filter.Doesn't seem ideal, but in reality they should never be called, andeven if they are they only return null.



152

* server/uk/org/iscream/filtermanager/HostInit.java (1.7): Addedthe required extra functionality that the was required to completethe setup with the host.


* server/uk/org/iscream/filtermanager/FilterManager.java (1.8): Themain method for the FilterManager.

* server/uk/org/iscream/rootfilter/RootFilterServant.java (1.2):This uses the the FilterThread, but I suppose ultimately it shouldhave it's own thread. It serves the correct purpose for now,although it's passed a null pointer as it's parent... which throwsan exception... but it gets caught.

* server/uk/org/iscream/filter/FilterThread.java (1.2): Addedparent filter passing, so the packet can be passed on. Also had tomake a quick fix because a null pointer exception was being thrownon the substring() part.

(I think)
