Show original parameters on process info/describe

[CGastrell]

This is just a suggestion I'd consider and enhancement (I read the contribution guidelines and I think it fits).

I think it would be helpful to know which parameters were used to start a process. I find myself deleting/stopping and recreating processes manually just to ensure I use the correct startup parameters (watch, ignore-watch, user, log-date-format, name, etc).

I know all these can be saved in a startup script, but I also think a little entry with the original start arguments wouldn't hurt and will come in handy when issuing:

pm2 describe <pid>
# or even
pm2 [prettylist | jlist]

Great work, cheers.

I can see two ways to do this:

• enable debugging with the environment variable: export DEBUG="pm2:monit"
• pm2 desc, prettylist, jlist as you mentioned

I don't think we would want to "pollute" the pm2 list with more parameters than we already have. Were would you like to see these parameters?

[CGastrell]

Well, pm2 describe <pid> would be a nice place, since it simply looks coherent to see these kind of information on a process while "describing" it.

I agree it wouldn't be wise to pollute pm2 [list | ls] anymore.

+1 to add this metadata to pm2 describe. This is straightforward, we just need to add some cols there to display more value of the pm2_env object: https://github.com/Unitech/PM2/blob/master/lib/CliUx.js#L63
