Python Nagios-compatible cluster check.
This nagios-compatible check aims to replace crm_mon -s and check_cluster provided in monitoring-plugins-cluster. It gives a better monitoring than the existing ones.
This script checks the state of resources and nodes. An alert is emitted if some nodes are offline or if some resources are in the 'failed' state.
This plugin can be run using an unprivileged user but requires a sudo configuration, such as:
User_Alias NAGIOS = nagios
Cmd_Alias NAGIOS_CMD = /usr/sbin/crm_mon --as-xml
NAGIOS ALL = (root) NOPASSWD: NOEXEC: NAGIOS_CMD
Checks the state of nodes: /usr/lib/nagios/plugins/check_cluster --nodes=yes --resources=no --perfdata=yes
Checks the state of ressources: /usr/lib/nagios/plugins/check_cluster --nodes=no --resources=yes --perfdata=yes
Checks the state of both nodes and ressources: /usr/lib/nagios/plugins/check_cluster --nodes=yes --resources=yes --perfdata=yes
The 'warning' and 'critical' thresholds deal with the number of failed resources.
Perfdata provide two metrics: 'offline_nodes' and 'failed_resources'.
