collectl

Extending collectl to send process data to graphite

The idea is to use collectl --export graphite,192.168.1.113 -sZ and generate graphite metrics like:

process.<CMD>.<PID>.cpu
process.<CMD>.<PID>.sys
...
process.<CMD>.cpu
process.<CMD>.sys
...

Potential problems:

• what happen when the process is runned by an interpreter (python blabla, python bleble, aggregated together?? no!)
• threads?
• aggregate info in collectl or in graphite (aggregation-rules.conf) ?
• lot of data to send to graphite
• how do you choose which subset to send?
• reused pids? (formatit.ph:9024)
