Re: [pcp] GSOC 2016 idea for PCP

[Charles Cui <charles.cui1984@xxxxxxxxx>]

Hi Lukas,Â

 ÂThanks for your reply! To answer your question. Yes, I have been selected in GSoC 2014Â

and successfully complete the project. Also thanks for providing such a great document.

I will read it carefully. By the way, is it enough to familiar with the documents for the current phase?Â

Let me know if you want some initial work to be done for this period.

Thanks, Charles.

Thanks for your interest in PCP! Currently, no proposed project has
been taken yet (official applications start on March 14), so no
worries there. It's great to see that you've subscribed to the
mailing list, we've also got a irc channel on freenode.net (#pcp) if
you prefer that form of communication.

Sounds like you've got some relevant programming language experience,
have you contributed to any open source projects, or Google Summer of
Code before?

A few more details about the task itself:

So, from a metrics collection standpoint, Performance Co-Pilot has two
components. The first is the pmcd (1) (Performance Metrics Collector
Daemon), which orchestrates client requests, and gathers the requested
metrics from the individual pmdas (Performance Metric Domain Agents).
Each of which define and collect a certain subset of metrics from the
system in question. The pmcd is written in C, and currently we have
pmdas (the agents), written in C/C++, perl, and python. We're looking
to extend pmdas to Golang as well, which will include writing some of
the standard pmda functions, as well as libraries, to interface between
pmdas written in Golang, to the C level apis and libraries which
currently exist.

If you're particularly keen to read more about the technical
implementation details within PCP, we've got plenty of documentation on
the website[1], specifically the Programmer's Guide[2] (Chapter Two is
specifically for writing a pmda).

Please feel free to reach out with any more specific questions you might
have, regardless if it's about the task, or the PCP community as a whole.

Cheers,

Lukas
