Monitoring docker containers from Rancher using nagios

[madhurima12]

Hi! I was wondering if there are any documentations on how to deploy a nagios Docker image using Rancher and use that to monitor other Docker containers running in a cluster managed by Rancher itself?

Nothing official for deploying via Docker/Rancher, but if you do some googling, you'll docker images for Nagios and plugins to check containers:

I found the docker image for nagios and have been able to deploy that through Rancher. I was unable to find an image for the plugins though. Could you help with that?

The default plugins should be in /usr/local/nagios/libexec, but other plugins will need to be installed manually if they are not already part of the image.
