port process collector

[siddontang]

So we can monitor current running process CPU, Memory, etc.

We can use https://github.com/danburkert/procinfo-rs, but it only works in unix, I think it is ok.

It would be nice to have support for other platforms too, eventually.

We can only focus on *nix (Linux + Mac OS X), we don't use Windows in our team.
This is optional metric, maybe you can help us support Windows or other platforms. :-)

procinfo is in fact Linux only. Still a good starting point though.

[siddontang]

Thanks @kamalmarhubi

We have not found any lib that supports all platforms, so now we only support Linux. If you find some or want to write one, please tell us :-)

Unfortunately, procinfo does not compile with stable and beta rust (danburkert/procinfo-rs#10 and danburkert/procinfo-rs#12).

I would remove procinfo temporary, and will add it back once the problem is solved.

[kamalmarhubi]

I just opened danburkert/procinfo-rs#14 which works around the overflow issue.

[overvenus]

That's cool! I will use procinfo once that is merged.

[kamalmarhubi]

danburkert/procinfo-rs#15 just got merged, should now work on stable.
