Let me know what you think of it.Â

That's weird, I've been sending to the mailing list as well as sending to you directly. Have you been receiving other emails from the mailing list? If we continue to have trouble I might just switch over to using my GMail account.

Sounds good. I'd suggest starting with the Python version of pmapi instead of the C pmpai.h version. It's most likely what we will want to use for writing a PCP-variant pidstat. Have a look at 'src/pcp/uptime/pcp-uptime.py' as a starting point.

If you've already had a look at the C pmapi.h thats great - what you've learned in that applies pretty much 1-to-1 for the Python pmapi.

For the first task of printing out 'disk.all.read', are you able to put the code up somewhere on-line that we can check out?

We'll have a chat again about pidstat once you've had a chance to play with pmapi.

Cheers!
Ryan
