Shell Script to Monitor process which stalled (cpu 100%)
Script: Use CutyCapt as an example
代碼:
#
# read last cutycapt pid
#
thisfile=/tmp/.cutycaptcheck
a=0
if [ -f "$thisfile" ]; then
a=`head $thisfile | cut -b1-5`
fi
#
# record Capt into .cutycapcheck again
#
top -b -n 1 | grep Cuty > $thisfile
#
# read current pid
#
b=`head $thisfile | cut -b1-5`
#echo "a == $a"
#echo "b == $b"
if [ x"$a" = "x" ]; then
logger "CutyCaptCheck: Do nothing (No A)"
exit
fi
if [ x"$b" = "x" ]; then
logger "CutyCaptCheck: Do nothing (No B)"
exit
fi
if [ "$a" -eq "$b" ]; then
logger "CutyCaptCheck: KILL pid = $a"
kill -9 $a
else
logger "CutyCaptCheck: Do nothing (A != B)"
fi
Then, modify the /etc/crontab if you it to run more frequently
e.g. Use "kill-CutyCapt" as an example
check if any CutyCapty stalled every 3 mins
代碼:
*/3 * * * * root /usr/sbin/killcuty
