Checks all processes and generates WARNING or CRITICAL states if the specified
metric is outside the required threshold ranges. The metric defaults to number
of processes.  Search filters can be applied to limit the processes to check.


Usage:
check_procs -w <range> -c <range> [-m metric] [-s state] [-p ppid]
 [-u user] [-r rss] [-z vsz] [-P %cpu] [-a argument-array]
 [-C command] [-k] [-t timeout] [-v]

Options:
 -h, --help
    Print detailed help screen
 -V, --version
    Print version information
 --extra-opts=[section][@file]
    Read options from an ini file. See
    https://www.nagios-plugins.org/doc/extra-opts.html
    for usage and examples.
 -w, --warning=RANGE
   Generate warning state if metric is outside this range
 -c, --critical=RANGE
   Generate critical state if metric is outside this range
 -m, --metric=TYPE
  Check thresholds against metric. Valid types:
  PROCS   - number of processes (default)
  VSZ     - virtual memory size
  RSS     - resident set memory size
  CPU     - percentage CPU
  ELAPSED - time elapsed in seconds
 -t, --timeout=INTEGER
    Seconds before plugin times out (default: 10)
 -v, --verbose
    Extra information. Up to 3 verbosity levels
 -T, --traditional
   Filter own process the traditional way by PID instead of /proc/pid/exe

Filters:
 -s, --state=STATUSFLAGS
   Only scan for processes that have, in the output of `ps`, one or
   more of the status flags you specify (for example R, Z, S, RS,
   RSZDT, plus others based on the output of your 'ps' command).
 -p, --ppid=PPID
   Only scan for children of the parent process ID indicated.
 -z, --vsz=VSZ
   Only scan for processes with VSZ higher than indicated.
 -r, --rss=RSS
   Only scan for processes with RSS higher than indicated.
 -P, --pcpu=PCPU
   Only scan for processes with PCPU higher than indicated.
 -u, --user=USER
   Only scan for processes with user name or ID indicated.
 -a, --argument-array=STRING
   Only scan for processes with args that contain STRING.
 --ereg-argument-array=STRING
   Only scan for processes with args that contain the regex STRING.
 -C, --command=COMMAND
   Only scan for exact matches of COMMAND (without path).
 -k, --no-kthreads
   Only scan for non kernel threads (works on Linux only).

RANGEs are specified 'min:max' or 'min:' or ':max' (or 'max'). If
specified 'max:min', a warning status will be generated if the
count is inside the specified range

This plugin checks the number of currently running processes and
generates WARNING or CRITICAL states if the process count is outside
the specified threshold ranges. The process count can be filtered by
process owner, parent process PID, current state (e.g., 'Z'), or may
be the total number of running processes

Examples:
 check_procs -w 2:2 -c 2:1024 -C portsentry
  Warning if not two processes with command name portsentry.
  Critical if < 2 or > 1024 processes

 check_procs -w 10 -a '/usr/local/bin/perl' -u root
  Warning alert if > 10 processes with command arguments containing
  '/usr/local/bin/perl' and owned by root

 check_procs -w 50000 -c 100000 --metric=VSZ
  Alert if VSZ of any processes over 50K or 100K

 check_procs -w 10 -c 20 --metric=CPU
  Alert if CPU of any processes over 10%% or 20%%
