[pcp] pmlogconf

[Nathan Scott]

Hi Ken,

I was taking someone through whats involved in setting up a pmlogger
farm the other day, and in the process mentioned pmlogconf (which I'd
not really used much before).  This was in the context of "how would
one setup a logging farm for a many-node hadoop cluster".

Its in a bit of a state, not sure if you want to take on renovations
in that area.  :)  I know Mark was looking for something similar for
getting loggers running in Fedora/RHEL out-of-the-box.  The Aconex
production environment uses a comparable process for setting up our
loggers, we might be convinced to convert if pmlogconf got a few more
features (in hindsight, we should've taken this on when we set that
up initially ... oh well).

Here's a few things that come to mind in terms of work-needed:
- its very IRIX-centric currently, will need to cull old metrics and
  introduce more appropriate ones from other platforms
- the metrics are all hard-coded in the script, a plug-in model more
  along the lines of pmieconf would seem better
- ability to probe a host (local/remote) for available metrics to
  automatically setup logging groups

If you (or anyone) take this on, happy to help with specific metrics
and processes we use to configure our production loggers for Linux &
Windows servers.

cheers.
