+Checks all processes and generates WARNING or CRITICAL states if the specified\n\
+metric is outside the required threshold ranges. The metric defaults to number\n\
+of processes. Search filters can be applied to limit the processes to check.\n"
+
+#define OPTIONS "\
+-w <range> -c <range> [-m metric]\n\
+ [-s state] [-p ppid] [-u user] [-r rss] [-z vsz] [-P %cpu]\n\
+ [-a argument-array] [-C command] [-v]"
+
+#define LONGOPTIONS "\
+Required Arguments:\n\
+ -w, --warning=RANGE\n\
+ Generate warning state if metric is outside this range\n\
+ -c, --critical=RANGE\n\
+ Generate critical state if metric is outside this range\n\
+Optional Arguments:\n\
+ -m, --metric=TYPE\n\
+ Check thresholds against metric. Valid types:\n\
+ PROCS - number of processes (default)\n\
+ VSZ - virtual memory size\n\
+ RSS - resident set memory size\n\
+ CPU - percentage cpu\n\
+ -v, --verbose\n\
+ Extra information. Up to 3 verbosity levels\n\
+Optional Filters:\n\
+ -s, --state=STATUSFLAGS\n\
+ Only scan for processes that have, in the output of `ps`, one or\n\
+ more of the status flags you specify (for example R, Z, S, RS,\n\
+ RSZDT, plus others based on the output of your 'ps' command).\n\
+ -p, --ppid=PPID\n\
+ Only scan for children of the parent process ID indicated.\n\
+ -z, --vsz=VSZ\n\
+ Only scan for processes with vsz higher than indicated.\n\
+ -r, --rss=RSS\n\
+ Only scan for processes with rss higher than indicated.\n\
+ -P, --pcpu=PCPU\n\
+ Only scan for processes with pcpu higher than indicated.\n\
+ -u, --user=USER\n\
+ Only scan for processes with user name or ID indicated.\n\
+ -a, --argument-array=STRING\n\
+ Only scan for processes with args that contain STRING.\n\
+ -C, --command=COMMAND\n\
+ Only scan for exact matches to the named COMMAND.\n\
+\n\
+RANGEs are specified 'min:max' or 'min:' or ':max' (or 'max'). If\n\
+specified 'max:min', a warning status will be generated if the\n\
+count is inside the specified range\n"
+
+#define EXAMPLES "\
+ check_procs -w 2:2 -c 2:1024 -C portsentry\n\
+ Warning if not two processes with command name portsentry. Critical\n\
+ if < 2 or > 1024 processes\n\
+ check_procs -w 10 -a '/usr/local/bin/perl' -u root\n\
