System and Server Status - Check Process - ClamAV and SpamAssassin server Monitor

Hello to eveyone

I'm trying to Monitoring "ClamAV Virus Scanning Server". Unfortunately in "Add monitor of type" it is not listed. So I tired to use "Check Process" type, and here come my answer. In "Check Process" type there is "Command to check for" field, I tried to use different kind of commands but nothing appears to work. Of course ClamAV process is up and running. Command "service clamd@scan.service status" works properly, I just don't know what should be the proper command to write in "Command to check for" field. Checked also online for any kind of documentation but I cannot find nothing on it or any example.

Any kind of help will be really appreciated. By the way I would like to do the same thing also for "SpamAssassin Filter Server".
