Processes plug-in for collectd doesn't seem collecting Per-process data.

Hi

We have Processes plug-in for collectd. I would like to collect system wide thread information.

• It doesn't exist in system wide information under processes. Under processes, the data is correct. (ps_state-sleeping.rrd matches the number of processes on the server itself.) 
  

ls processes

fork_rate.rrd  ps_state-blocked.rrd  ps_state-paging.rrd  ps_state-running.rrd  ps_state-sleeping.rrd  ps_state-stopped.rrd  ps_state-zombies.rrd

• It's supposed to have thread data per process in ps_count.rrd as said in https://ssc-serv.com/processes.shtml . However, graphite shows all data per process are 0 .

 ls processes-Passenger

ps_code.rrd  ps_count.rrd  ps_cputime.rrd  ps_data.rrd  ps_pagefaults.rrd  ps_rss.rrd  ps_stacksize.rrd  ps_vm.rrd

Configure file:

 cat /etc/collectd.d/process-Passenger.conf

## Note - the Processes plugin is already loaded..

# LoadPlugin processes

## embedded into passenger - master and worker process(es)

<Plugin processes>

        Process "Passenger"

</Plugin>

We have such Passenger thread on the server.

 ps -eLf | grep Passenger

xxxxxx    2293     1  2321  0   25 02:27 ?        00:00:00 Passenger RubyApp: /opt/xxxxxx/app/public (production)

Why collected doesn't collect those information?

Thanks,

Bin

This one works.

<Plugin processes>

        ProcessMatch "Passenger" "Passenger"

</Plugin>
