Re: [performancecopilot/pcp] pcp.env: _get_pids_by_name returns all pmcd pids on machine with containers (#101)

[test-account-0 <notifications@xxxxxxxxxx>]

Because I want to monitor metrics from pcp with a nagios script. These are not docker containers but kind of "normal machines" (one can ssh to them, install stuff and such). I already have automation to set up services and monitoring per host.
I haven't yet checked monitoring containers from outside with pcp, but it would look weird in nagios - all checks on one machine for all containers on this machine instead of on a specific container. And also it is a lot of work to change/write new puppet modules to make it happen automatically.

Apart from that, why the function _get_pids_by_name gets all pids of a specific program and not only those that a parent is pid 1? Is it used not only in init scripts?
