bpi monitor 1 process between 2 servers

[kendallchenoweth]

I'd like to use BPI to setup monitoring of a process between a cluster of two servers. Between server A and server B, I'd like to report OK if only one instance of crond is running on one of the servers. I can setup BPI to alert if no instances of crond are running on a client. How can I setup BPI to alert if both server A and server B have the process running?

Thanks!

That functionality doesn't currently exits, great idea though, I've created a feature request for this:

Code: Select all

NEW TASK ID 6863 created - Nagios XI Feature Request: BPI Wizard - Add functionality to alert if service is running on multiple hosts

You may be able to use the check_cluster plugin and the negate plugin to achieve the functionality you are looking for, I'll lab it up and see if it'll work.


Thank you

Ok, here is how I was able to make this work:

1. Make sure that you are monitoring the service (SSH in this example) on both servers (you can disable notifications for them), these service checks are what will be used by the check_cluster plugin.

2. Create a new command:
- Command Name: negate_check_service_cluster
- Command Line: $USER1$/negate -w OK -o CRITICAL -s '$USER1$/check_cluster --service -l $ARG1$ -w $ARG2$ -c $ARG3$ -d $ARG4$'
- Command Type: check command

3. Create the service:
- Description: SSH_Cluster
- Check command: negate_check_service_cluster
- $ARG1$: SSH_Cluster
- $ARG2$: 0
- $ARG3$: 1
- $ARG4$: $SERVICESTATEID:host1:SSH$,$SERVICESTATEID:host2:SSH$


Let me know if you have any questions
