Help needed: List of all processes in a Katello deployment

Hey,

one thing I really like about Puma app server is how consistently it renames process titles:

foreman   9282  0.0  2.9 947964 293884 ?       Ssl  Dec02   0:48 puma 5.3.2 (unix:///run/foreman.sock) [foreman]
foreman   9308  0.0  4.1 992672 416576 ?       Sl   Dec02   0:39 puma: cluster worker 0: 9282 [foreman]
foreman   9314  0.1  5.3 1143056 536972 ?      Sl   Dec02   1:15 puma: cluster worker 1: 9282 [foreman]

It is very much clear that these processes are instances of foreman app, which is the master process and which are workers. It also renames them consistently which is actually something that is very much needed for the Prometheus Ruby client library if my patch gets accepted:

https://github.com/prometheus/client_ruby/pull/235

Now, in a different thread there is a user asking for help with increased memory problem and we struggle to understand which process does what. In this case, the suspicious process is named just rails and it is likely the Katello Event Daemon.

So what I propose is to find all of these processes and then make patches so process title is changed during startup so they appear nicely in utilities like top or ps. But since I do not understand all the details of Katello or other plugins, help me to identify with me all the Foreman and Katello related processes which are running on a Katello deployment (the snippet is from Satellite 6.10):

This is Tomcat hosting Candlepin, I am not running Puppet Server on this host. Although Java processes are ugly (many arguments) these are typically single-process multi-threaded deployments so it is not an issue. Skipping.

Apache httpd, not much to see here. I am assuming we only have one instance, if we have multiple then we should consider tagging them.

Puma, obviously. A nice example how I would like to see the other processes too.

Sidekiq is the first problem - although it tries to nicely inform about how many workers are busy, we appear to spawn three instances without any identifier. Quickly looking into the CLI code, it looks like sidekiq appears to support --tag option. I suggest to tag them with something like sidekiq-dynflow or whatever we use sidekiq for.

Can you help me to identify the three instances? What are these?

Pulp API, not bad, little bit cryptic. I wonder if it can be configured for something better and it can and it is easy! From the docs:

If you install the Python package setproctitle Gunicorn will set the process names to something a bit more meaningful. This will affect the output you see in tools like ps and top . This helps for distinguishing the master process as well as between masters when running more than one app on a single machine. See the proc_name setting for more information.

Smart proxy, I will look into what can be done here. Perhaps just renaming this to foreman-proxy could do it, although that is just a change for nothing.
