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, by executable name, by command
|
||||
line pattern matching, or by username (in this order or priority. Procstat
|
||||
plugin will use `pgrep` when executable name is provided to obtain the pid.

|

measurements for every process specified. A prefix can be set to isolate

individual process specific measurements.

|

The plugin will tag processes according to how they are specified in the configuration. If a pid file is used, a "pidfile" tag will be generated.
|
||||
On the other hand, if an executable is used an "exe" tag will be generated. Possible tag names:
|
||||
|
||||
* pidfile
|
||||
* exe
|
||||
* pattern
|
||||
* user
|

|

Additionally the plugin will tag processes by their PID (pid_tag = true in the config) and their process name:
|
||||
|
||||
* pid
|
||||
* process_name
