Zabbix Pacemaker Template

A Zabbix template for pacemaker cluster monitoring with virtual ip.

Requires

Zabbix >=3.4 (because the template uses dependent items and value preprocessing features that were introduced in 3.4)

Metric	Description
pacemaker.cluster.dc	Current cluster DC (Designated Coordinator)
pacemaker.cluster.failed_actions	The current number of failed actions
pacemaker.cluster.maintenance	Shows if the cluster is in the maintenance state
pacemaker.nodes.offline	The current number of offline (or in the shutdown state) nodes
pacemaker.process.corosync.active	Shows if corosync daemon is in the running state
pacemaker.process.pacemakerd.active	Shows if pacemakerd daemon is in the running state
pacemaker.resources.failed	The current number of failed (non active or blocked) resources
pacemaker.status	Service item for data gathering
system.hostname	Node hostname. If it changes, it could mean that the VIP has been moved to another node

You need to configure every cluster nodes as shown below:

Copy "configs/pacemaker.conf" into your zabbix_agent include folder (default: /etc/zabbix/zabbix_agentd.d/) or manually add that UserParameter to config:

UserParameter=pacemaker.status, sudo /usr/sbin/crm_mon --as-xml

Restart zabbix_agent
Copy "configs/zbx_pacemaker.sudoers" into /etc/sudoers.d or manually add that rule:

zabbix ALL=NOPASSWD: /usr/sbin/crm_mon --as-xml

Import "template_app_pacemaker.xml" into zabbix as template
Create "virtual" host object with virtual ip address as network interface and link this template.

You can check that everything works correctly by using crm_mon dumps in “tests” folder.

For this purpose you need to copy dumps to cluster nodes (or use your own) and add this UserParameter to config:

UserParameter=pacemaker.test[*], cat /etc/zabbix/zabbix_agentd.d/tests/$1

Then change "pacemaker.status" item key to "pacemaker.test[sampleN.xml]" and save.

Also you could manually edit sample file for test different cluster states.
