Downloading the Installation PackageYou can download an installation package and install the components on one or more hosts. Theinstallation runs silently with the information entered during package creation.

RecommendationIf you defined the BMC ProactiveNet Integration Service variable for PATROL Agents in theinstallation package, ensure the agents are started in phases. Do not start newly deployedagents all at once. Start and configure monitoring for the agents in planned phases to reducethe performance impact on the Integration Service nodes and on the BMC ProactiveNetServer associated with the automatic workflow process.

1. Log on to BMC ProactiveNet Central Monitoring Administration from the computer on whichthe PATROL Agent is installed.

2. Click the Repository drawer and select Monitoring Repository.

3. (Optional) To filter the list of installation packages, select an operating system from the Filter by Operating System list.

4. Click the link for the installation package that you want to download.

5. Through the browser's download dialog box, save the installation package.

Installing the Package1. Copy the installation package to the host where BMC ProactiveNet Performance Management - HP

EVA Storage Monitoring needs to be installed

2. Extract the installation package as appropriate for your operating system. The package isextracted to the bmc_products directory on the current host.

3. From the bmc_products directory, run the installation utility for your operating system:

(UNIX or Linux) RunSilentInstall.sh

(Microsoft Windows) RunSilentInstall.exe

The package is installed on the current host. If the package includes a BMC PATROL Agent, theagent sends a configuration request by passing its tags to BMC ProactiveNet Central MonitoringAdministration, via the Integration Service. Central Monitoring Administration evaluates policiesthat match the tags, determines the final configuration to be applied, and sends theconfiguration information back to the agent. Monitoring is based on the configurationinformation received by the agent.

If no policy matches the tags associated with the agent, the agent does not receive configurationinformation. The agent does not begin monitoring until a matching policy is created.

BMC ProactiveNet Performance Management - HP EVA Storage Monitoring is configured whenyou create a policy. A policy is a template containing the configuration of a PATROL Agent. Apolicy can be assigned to one or more PATROL Agents using a unique tag (Central MonitoringAdministration tag), and a PATROL Agent can be assigned one or more policies with differentpriorities.

If you have not already added the Central Monitoring Administration tag to your PATROL Agentsduring the solution installation, then you must manually assign the tag after you have configuredthe policy. For details, see Adding Central Monitoring Administration Tags.

Configuring General SettingsThrough the General tab of the Add Policy dialog, you can create a new policy. A policy specifies aset of actions to be taken when a specific condition on the PATROL Agent is fulfilled. First andforemost, actions include monitor configuration. Once a monitor is configured, policies can alsospecify threshold creation and the setting of baselines. A policy can also include intelligentserver-side thresholds so that IT administrators can immediately be alerted on potentialproblems.

Field Instructions

Name Enter a policy name. Policy names must be unique. In an environment with tenants, policy names must be unique for a single tenant

Tenant(For environmentswith tenants)

Select a tenant name. See Policies and tenants for details. Global indicates a policy applicable to all tenants.Provider indicates a policy applicable to the cloud service provider

Enable policy Select this option to enable the policy, or clear the option to disable the policy. Theoption is selected by default. If you clear the option, the policy and itsassociations remain intact, but the policy configuration is not applied until thepolicy is enabled again.

Precedence Enter a number from 0 to 999.

Description (Optional) Enter a policy description.

Tag Enter a Central Monitoring Administration tag.Policies are applied to BMC PATROL Agents with matching tags.Tags are case sensitive and cannot contain spaces or any of the followingcharacters: /, \, {, }, <, >, ‘, “, &.

Policy precedence

When more than one policy is applied to a BMC PATROL Agent and BMC ProactiveNet ChildServer, configuration is a union of every attribute defined by the policies. If a conflict arises (thatis, two policies configure the same attributes), it is resolved in one of the following ways:

When you are creating or editing a policy, you can add and configure monitor thresholds. The Add Thresholds dialog box presents threshold configuration fields for BMC ProactiveNetmonitors that are configured through Central Monitoring Administration.

For details about baselines and Key Performance Indicators (KPI), see BMC ProactiveNet CentralMonitoring Administration or BMC ProactiveNet documentation or refer to the ManagingBaselines and Key Perf ormance Indicators section. For details about the monitored attributes,refer to the specific monitor type in the Ref erence Guide section.

Before you begin

Ensure that your monitor configuration is complete before thresholds are applied. Thresholdscannot be applied to monitors that are not configured through Central MonitoringAdministration. If you have not done so already, please refer to the section Configuring MonitorSettings.

Recommended Thresholds

Thresholds define acceptable high and/or low values for the data collected. Thresholds can becreated as part of a policy that can be applied to multiple monitor types on multiple BMC PATROLAgents. The Ref erence Guide provides a list of monitor types with their respective attributes and, whenmeaningful, a recommended threshold.

Configuring Monitor ThresholdsTo configure monitor thresholds:

1. Create a new policy or edit an existing one.

2. Select the Threshold Configuration tab and click Add .

3. In the Add Thresholds dialog box, select the relevant Solution, Version, and Monitor Type.

4. In the Instance Name field, specify the instance to which the threshold configuration will beapplied. You can either use a string or the following regular expression patterns: ?, +, *, ( ), |,[ ], { }, ,̂ $,

5. Select Match Device Name if you want the entire <deviceName>\<instanceName> string tobe considered.

6. From the Attribute list, select a monitor attribute.

7. In the Threshold section:

Select the threshold type.

Set the threshold parameters values.

Click Add.

Detecting High Processor UtilizationDetecting a high processor utilization is important to prevent controllers overloading that canlead to unpredictable performance degradations. To detect high processor utilization with BPPM,you can create a specific view to compare Processor Utilization and the Transfer Byte Rateattributes of all the controllers in your HP EVA storage systems and then determine which onemay constitute a bottleneck.

Creating a High Processor Utilization View1. Log on to the BMC ProactiveNet Operations Console.

2. Display the list of devices monitored by BPPM:

In the Navigation frame, select the Main drawer.

Click Devices.

Click to display the list of devices in a grid.

Displaying devices in a grid

3. In the Devices drawer, click the first disk array for which you need to compare the controllers'processor utilization.

4. The list of monitors for disk array is displayed. Expand the Controllers monitor.

10. The High Processor Utilization view is now created and available under the Views & Graphsdrawer in the Navigation pane.

11. Repeat the procedure to add to this view the Processor Utilization attributes of all thecontrollers in your HP EVA disk array.

Once all graphs are stored in the view, it becomes easy to compare the controllers' respective Processor Utilization and Transfer Byte Rates. Ensure that the Processor Utilization is lower than80%. A processor utilization over 80% means that this controller is overloaded and that itconstitutes a bottleneck for the storage system.

Verify the Transfer Byte Rate of your controllers. If the value of this attribute stays low – whilethe overall processor utilization is high – it indicates that the node is performing "nonproductive" tasks. It then may become critical to determine the source of activity that generates

9. Create a graph for the second controller and add it to the Controllers Workload Balance view.You are then able to easily compare the values of both controllers to evaluate the workloaddistribution.

For example, if the throughput on one controller is significantly higher than the other one, itindicates that one on the controllers may constitute a bottleneck for the subsystem that could bealleviated by better sharing the load between the controllers.It is recommended to pay close attention to which logical drive is handled by which controller,depending on the activity of this logical drives to be able to reallocates controller to drive I/O
