Jerry / Marcin,
Are you aware of PCP (http://oss.sgi.com/projects/pcp)?
It's a general framework for working with performance instrumentation.
It deals with naming metrics and instances of metrics, programatically
discovering and working out the values, semantics, units and dimensions
of metrics. It's open source and has been ported to a range of
platforms, including Solaris, IRIX and many flavours of Linux.
It would be possible to implement the perfcounter daemon as a general
mapping layer between PCP metrics and the registry interface. This would
have some immediate advantages:
1. You can support performance counters on Linux and non-Linux
platforms without any extra code.
2. It easier to add support for more metrics (eg. PCP on my
laptop currently exports ~580 metrics).
3. It is quite easy to add your own metrics into PCP, so
third-party metrics could automatically be provided to windows
This isn't a piece of work I can do myself right now, but I'm happy to
provide more PCP info if you are interested.
