check_crs

Nagios plug-in for Oracle clusterware (11g and above) It checks: a) clusterware stack status b) OCR registry integrity c) Voting disks status d) resource status (ONLINE/OFFLINE); you can define exceptions with exclude option e) database instance status - if it is running as configured f) database service location - if it is running on preferred instance This plug-in needs to be run as clusterware binaries owner (usually oracle). Configure sudo to work with nrpe-owner. Run 'check_crs --help' for full description. Setup: 1. disable 'requiretty' for nrpe-owner in /etc/sudoers Defaults:nagios !requiretty 2. enable sudo for nrpe-owner to run this script nagios ALL=(oracle) NOPASSWD: /usr/lib64/nagios/plugins/check_crs 3. edit nrpe.cfg and insert required checks with options: command[check_crs_clusterstatus]=sudo -u oracle /usr/lib64/nagios/plugins/check_crs --crs_home=$CRS_HOME --action=clusterstatus command[check_crs_ocrcheck]=sudo -u oracle /usr/lib64/nagios/plugins/check_crs --crs_home=$CRS_HOME --action=ocrcheck command[check_crs_votedisk]=sudo -u oracle /usr/lib64/nagios/plugins/check_crs --crs_home=$CRS_HOME --action=votedisk command[check_crs_resstatus]=sudo -u oracle /usr/lib64/nagios/plugins/check_crs --crs_home=$CRS_HOME --action=resstatus --exclude=res1.example,res2.example command[check_crs_instancestatus]=sudo -u oracle /usr/lib64/nagios/plugins/check_crs --crs_home=$CRS_HOME --action=instancestatus command[check_crs_dbservicelocation]=sudo -u oracle /usr/lib64/nagios/plugins/check_crs --crs_home=$CRS_HOME --action=dbservicelocation Sample output: check_crs --crs_home=/oracle/gridhome --action=clusterstatus [OK] All clusterware services are up (clusterware version: 11.2.0.3.0) check_crs --crs_home=/oracle/gridhome --action=ocrcheck [OK] Cluster registry integrity check succeeded - (+CRS: succeeded) check_crs --crs_home=/oracle/gridhome --action=votedisk [OK] Voting disks status check succeeded - (/dev/oracleasm/crs_disk_01p1) [CRS] check_crs --crs_home=/oracle/gridhome --action=resstatus [OK] All required resources are up check_crs --crs_home=/oracle/gridhome --action=instancestatus [OK] All required database instances are up check_crs --crs_home=/oracle/gridhome --action=dbservicelocation [OK] All services are running on preferred instances
