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)
