Hi, Here's the code for supporting nagios plugins in lrmd: https://github.com/gao-yan/pacemaker/commits/nagios
A new resource class "nagios" is introduced. Actions: - probe: A resource defined for a resource container is not probed. (We can also add a condition in pengine to just avoid probing a nagios class resource.) - start: Invokes the nagios plugin with specified parameters (Maps the instance attributes to the long options of the nagios plugin). If it returns non-OK, re-invokes it after some delay (delay = start_timeout / 10), until it returns OK or exceeds the start timeout. - monitor: Recurring invocation to the nagios plugin with specified parameters. - stop: Nothing special is done. The recurring monitor is canceled anyway. - metadata: Reads the corresponding metadata from a xml file in NAGIOS_METADATA_DIR. (As we know nagios plugins don't support metadata. The current plan is to generate the corresponding metadata according to the help of the plugins, and put them into NAGIOS_METADATA_DIR for use -- Dejan already has progress on this. Thank, Dejan!) For nagios plugins, the exit code are: STATE_OK = 0, STATE_WARNING = 1, STATE_CRITICAL = 2, STATE_UNKNOWN = 3, STATE_DEPENDENT = 4, AFAICS, STATE_OK should map to PCMK_EXECRA_OK, and the others should all belong to PCMK_EXECRA_UNKNOWN_ERROR. Well, apparently, there's no code to express "NOT_RUNNING" in nagios plugins. I think it should be fine, since there's no probe. Any suggestions are appreciated!
