Hello!
When adding a service in Linux (ds_agent) using process discovery. In my case, an antivirus is Trend Micro Deep security. I can’t manage the following
How can I do this at checkmk?
Do you want to monitor a systemd service?
No, I don´t. The service I want to monitor is called ds_agent is from an antivirus. And about this service
When it does not exist in a host I want it to indicate an OK
When this service exists en los host I want a Warning
I think this is not possible. I’ve found two rules State and count of processes in Parameters for discovered services and Process Discovery in Discovery - automatic service detection.
If you go to Process Discovery and activate the help:
Maybe you need an own check? In this case maybe a local check is enough?
Create a manual check (WATO → Manual Checks) for State and count of processes. Choose some conditions (like hostname, folder, or tags) and set the following attributes:
With these levels the check goes to the warning state if more than zero processes with the name /bin/sleep exists. Change that name to the name of your process, e.g. /bin/ds_agent (or whatever path makes sense).
But please be aware that the check will only go WARN if the process runs at the very moment the check_mk_agent queries the process list. I don’t know about ds_agent but if it usually runs for just a few seconds once in a while then you won’t benefit from this check.
Thank very much for your answer!!
This works
I would assume this goes CRIT if a process exists, not WARN as the OP asked for.
The -1 seems a bit exaggerated because it means “go CRIT if there are less than -1 processes” (i.e. -2 processes or even fewer). But that’s rather an academic problem. I would set Critical above to a value that is unlikely to occur if I only want WARNings.
