[Xymon] Too many procs

[Alexander Bech]

Have a solution.


# clientlocal.cfg on xymon-server:
toomanyprocs:/usr/sbin/apache2 -k 
start|/usr/sbin/anotherproc|/usr/sbin/anotherproc2


# ps section on xymon-client:

echo "[ps]"
PROCSTOCUT=`cat ${LOGFETCHCFG} | grep "^toomanyprocs:" | awk -F: '{print 
$2}'`
if test -z "$PROCSTOCUT"; then
  ps -Aww f -o 
pid,ppid,user,start,state,pri,pcpu,time:12,pmem,rsz:10,vsz:10,cmd
else
  ps -Aww f -o 
pid,ppid,user,start,state,pri,pcpu,time:12,pmem,rsz:10,vsz:10,cmd | 
egrep -v "${PROCSTOCUT}"
  ORIGIFS=${IFS}; IFS="|"
  for PROC in ${PROCSTOCUT}
  do
     ps -Aww f -o 
pid,ppid,user,start,state,pri,pcpu,time:12,pmem,rsz:10,vsz:10,cmd | grep 
"${PROC}" | grep -v grep | head -n 2
  done
fi
IFS=${ORIGIFS}

Result: only two lines in client message.
