Telegraf plugin: procstat

Description

The procstat plugin can be used to monitor system resource usage by an individual process using their /proc data.

The plugin will tag processes by their PID and their process name.

Processes can be specified either by pid file or by executable name. Procstat plugin will use pgrep when executable name is provided to obtain the pid. Proctstas plugin will transmit IO, memory, cpu, file descriptor related measurements for every process specified. A prefix can be set to isolate individual process specific measurements.

Example:

[[inputs.procstat]]
  exe = "influxd"
  prefix = "influxd"

[[inputs.procstat]]
  pid_file = "/var/run/lxc/dnsmasq.pid"

The above configuration would result in output like:

> procstat,name="dnsmasq",pid="44979" cpu_user=0.14,cpu_system=0.07
> procstat,name="influxd",pid="34337" influxd_cpu_user=25.43,influxd_cpu_system=21.82
