Data gathering

• Active / Passive agents •

Firewalls

• • •

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

•

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

• Agentless SNMP WMI

• Historical data

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

• •

Proxies just gather data and forward it

Nodes have their own admin interface

• Proxies 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!

The End!
