Sounds like you are picking it up quickly, that's great. The second task there
is about writing new performance analysis tools to display performance data in
a variety of ways, using the PCP client APIs. ÂÂ

In the case of the htop tool, it would involve working on making htop able to
consume data from PCP using the PMAPI (instead of, or in addition to, directly
accessing the machine it is running on). http://hisham.hm/htop/ - all C code.
Once implemented, you would then work with the htop authors/maintainers to see
if the new code could be merged into the master htop git tree (as a bonus).

For the other, less complex tools - like pidstat - the aim is to write python
scripts to implement the same functionality as the original tool. Again, that
involves accessing the metric values using the PMAPI (as you read about in the
"PCP Programmers Guide") such that the data is accessible from pmcd(1) - either
remotely or locally - and also via recorded PCP archives.

Thank you for the reply, so first thing I will do is to download and build htop from source and try to dive in into the code to get its better understanding.

Once I am done with that we can discuss further on this. Meanwhile I am trying to set up a bouncer to log messages on irc thus I will stick to the mailing list for some time.
