Subject: multi-instances: how to discriminate "master" in process list
Hi all,
I have a multi-instance setup.
By doing "ps -ef", as expected, I see a lot of "master" processes.
Is there a way to see which master is related to which instance at a glance?
So that I can rapidly say this pid is for instance 1, and so on...
What I am looking at is, ideally, a way to see the process name something like
"master-instance1"
i.e. rspamd does exactly this, assigning a different process name just to
explicit the "incarnation" of that process
Thank you in advance
Marco
