nagios monitoring a failover process

[chrislewis28]

Hi,

We have a service which runs in a failover mode and I would like Nagios to monitor it. The logic would be:

check if process is running on host A if yes return OK status, if no check if process is running on host B if yes return OK status if no return critical status.

Is there a way Nagios can do this without me having to write my own plugin?

Hi chrislewis28,

I think you may be looking for service dependency.

Check these links, they should provide you with the details.

Good luck!

Kind Regards,

I would agree, that service dependencies may be one way to do it, however it sounds like you could write a script that takes both hosts and the service to check. Checks the first provided, if off, checks the second host, if both are off fails critical. Off hand I do not know of a check that does this, but with more information regarding what this service is maybe we can find something.
