The other day I was trying to kill a master instance of Mesos but couldn't find it. I tried ps auwg | grep mesos but no Mesos processes turned up. I knew Mesos was running since I could access the http interface on port 5050, so in the end I ran:

lsof -n -i:5050

This returns a list of all processes listening on port 5050 including their PID.
