# 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:
|
|
|
|
```
|
|
[procstat]
|
|
|
|
[[procstat.specifications]]
|
|
exe = "influxd"
|
|
prefix = "influxd"
|
|
|
|
[[procstat.specifications]]
|
|
pid_file = "/var/run/lxc/dnsmasq.pid"
|
|
```
|
|
|
|
The above configuration would result in output like:
|
|
|
|
```
|
|
[...]
|
|
> [name="dnsmasq" pid="44979"] procstat_cpu_user value=0.14
|
|
> [name="dnsmasq" pid="44979"] procstat_cpu_system value=0.07
|
|
[...]
|
|
> [name="influxd" pid="34337"] procstat_influxd_cpu_user value=25.43
|
|
> [name="influxd" pid="34337"] procstat_influxd_cpu_system value=21.82
|
|
```
