Here we strip the command details, so most commands will be bash or python, count them seems meaningless and wasteful
How about excluding such processes

I removed args because omiagent will also have args like /opt/omi/bin/omiagent 9 10 --destdir / --providerdir /opt/omi/lib --loglevel WARNING, I think the args is useless.

Get process memory consumption by ps rss, report those who use more than 500M to save space in prometheus. Also defined an alert rule for process
omiagentandomsagent, these two processes are frequently causing OOM in azure VM, which DRI should take care of.
