Data gathering

• Active / Passive agents

• Firewalls

• Agentless

• Polling TCP/IP (FTP / HTTP / SMTP etc.)

• SNMP

• WMI

• Historical data

• Detailed (eg. Last 7 days) vs Trends (eg. Last 365 days)

Organising Hosts

• Users and usergroups

• Permissions apply only to usergroups and hostgroups

• Hostgroups => Hosts => Items / Graphs / Triggers

• Templates

• Can have Items / Graphs / Triggers

• Scalable

Graphs & History

• History

• Look at ‘Raw’ data

• Graphs

• Auto-generated or pre-defined

• Assign to template

• Screens

• Combine graphs and other data into a large display

• Slideshows

• Loop through screens

Alerting & Notifications

• Triggers

• Host discovery

• Arbitrary condition (CPU > 90% for 5mins?)

• Actions

• What to do when a trigger fires?

• Send notification / Execute command

Distributed setups

• Good for remote sites with poor connectivity

• Nodes

• Allow remote sites to administer autonomously

• Nodes have their own admin interface

• Proxies

• Proxies just gather data and forward it

• Save bandwidth/connections

• Mix and match is possible!

WEB Monitoring

• Monitor websites by retrieving pages

• Allows scenarios

• Log in to frontend => go to ‘My Profile’

• Monitor HTTP status codes or grep for text

• Not templatable yet :(

New in 1.8: API

• First version with API, so it’s a work in progress

• Makes external tools easier

• Zabcon (http://trac.red-tux.net/wiki/zbx_api/zabcon)

• Makes external development easier

• Tribily’s drupal module (http://github.com/Tribily)

• Great future for zabbix!

Demo-time!
