This plugin need sudo to work with nrpe the nrpe-owner will use the following commands with sudo:
sudo-User command CRS_OWNER $CRS_HOME/bin/crsctl CRS_OWNER $CRS_HOME/bin/orabase CRS_OWNER $CRS_HOME/bin/ocrcheck CRS_OWNER $CRS_HOME/bin/ocrconfig
we do only a small check of running processes due to crsctl will return a hughe amount of errors when crsd isn't running
example sudo-setup for nrpe: Defaults:nrpe !requiretty Cmnd_Alias CRSCTL = /u01/app/11.2.0.3/grid/bin/crsctl Cmnd_Alias ORABASE = /u01/app/11.2.0.3/grid/bin/orabase Cmnd_Alias OCRCHECK = /u01/app/11.2.0.3/grid/bin/ocrcheck Cmnd_Alias OCRCONFIG = /u01/app/11.2.0.3/grid/bin/ocrconfig User_Alias NRPE_ADMIN = nagios, nrpe NRPE_ADMIN ALL = (oracle) NOPASSWD: CRSCTL, ORABASE, OCRCONFIG, OCRCHECK
The check works but I was hoping it would have options other than just saying "All services are OK" (that is to check various options). I noticed in the case statement for default it is running 3 separate functions but they don't stand alone so one would have to modify the case to do any of the options individually AND modify the functions to provide other information to make them stand alone. Also some comments on the sudo setup: If you're using nagios rather than nrpe as your user running the nrpe plugin you'd have to set the NRPE_ADMIN user accordingly. If you're using a different path than the example you don't have to modify the script but do have to insure that path is in your sudo Cmnd_Alias instead of the example path. You can run the !requiretty for the nagios (or nrpe) user and leave the default for all other users as requiretty.
