Process Elapsed Time and CPU Usage Time

Just a memo for myself.

When a process hasn't been restarted in a long time, restarting it makes me a little nervous, so I want to know roughly how long it has been running.
With that in mind, I use the following command to check.

$ ps -eo pid,comm,etime,time  | grep node
  591 node            51-20:47:21 00:01:54
 2255 node            23-18:07:58 00:01:18

OPTION	Explain
pid	Process ID
comm	Command
etime	Elapsed time since the process started
time	CPU usage time

Of course you can also grasp how heavily the CPU is being used, so it comes in handy for all sorts of things.
