nagios的客户端nrpe自带了check_procs可以监控进程的数量（nrpe2.13带有这个脚本，早期版本不确定）
【基本参数】
[root@local libexec]# ./check_procs -h check_procs v1.4.15 (nagios-plugins 1.4.15) 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-c [-m metric] [-s state] [-p ppid] [-u user] [-r rss] [-z vsz] [-P %cpu] [-a argument-array] [-C command] [-t timeout] [-v] Options: -h, --help Print detailed help screen -V, --version Print version information -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 connection times out (default: 10) -v, --verbose Extra information. Up to 3 verbosity levels 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). 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%% Send email to [email protected] if you have questions regarding use of this software.

【简单例子】
创建监控警告：进程名是salt-minion数量在1以外的
[root@locallibexec]# ./check_procs -w 1:1 -C salt-minion PROCS OK: 1 process with command name 'salt-minion
【一些总结】
1.如果判断进程名
用扩展信息模式，就可以指定进程名字，进程状态等信息
[root@local libexec]# ./check_procs -vv -w 1:1 -C salt-minion CMD: /bin/ps axwo 'stat uid pid ppid vsz rss pcpu comm args' Matched: uid=0 vsz=361980 rss=26648 pid=27079 ppid=1 pcpu=0.00 stat=Sl etime= prog=salt-minion args=/usr/bin/python2.6 /usr/bin/salt-minion -d PROCS OK: 1 process with command name 'salt-minion' [root@local libexec]# /bin/ps axwo 'stat uid pid ppid vsz rss pcpu comm args' | grep salt-minion S+ 0 3628 3505 6056 576 0.0 grep grep salt-minion Sl 0 27079 1 361980 26648 0.0 salt-minion /usr/bin/python2.6 /usr/bin/salt-minion -d
