[Nagiosplug-devel] Status flags supported by check_procs

Hi Jochen,

I tried to configure both 1.4.15 and 1.4.16, and on the same box where the
rpm is compiled I see the same ps command you see:

 /usr/local/src/nagios-plugins-1.4.16 > grep -A 1 -B 1 '[^A-Z_]PS_' config.h
/* Number of columns in ps command */
#define PS_COLS 9

/* Verbatim command to execute for ps in check_procs */
#define PS_COMMAND "/bin/ps axwo 'stat uid pid ppid vsz rss pcpu comm args'"

/* Format string for scanning ps output in check_procs */
#define PS_FORMAT "%s %d %d %d %d %d %f %s %n"

/* Whether the ps utility uses the "procetime" field */
/* #undef PS_USES_PROCETIME */

/* Variable list for sscanf of 'ps' output */
#define PS_VARLIST
procstat,&procuid,&procpid,&procppid,&procvsz,&procrss,&procpcpu,procprog,&pos


Problem is then the repo, but the OS seem fine to compile nagios-plugins on
my own. Even if I'm sure something won't be right with dependencies.

I think -ss would be enough for me, as my final checker would be:

/usr/lib64/nagios/plugins/check_procs -c 1:1 -ss -C schedule_cron
