As part of our monitoring for processes, there are 2 options for monitoring the count of processes:
This is useful for getting alerted if there are suddenly a large number of processes running on a server, or more than you would expect in normal operations.
Monitoring by process name
This is useful if you know there should be a minimum number of processes at all times e.g. Apache workers; or want to know when the number of processes goes over a certain threshold when you might need to do upgrades e.g. Apache workers going over the capacity of the server.
Here you specify the name of the process, which can be an exact match or a regular expression.
