Hi SRM,
I’m not familiar with Bamboo, so I don’t know all the specifics for it. But assuming you are running Bamboo yourself on a VM you have access to, then you probably have a CheckMK agent running on the VM already.
If so, then the easiest way to get started is adding a Local Check to the agent.
Check out the docs on how to create your own local check: https://checkmk.com/cms_localchecks.html
