Hey, I'll give guidelines for this script:
conf file (example):
test.prog:5:/usr/bin/test.prog
script (in crontab, runs let's say every 5 minutes):
cat conf.file | while read line
do
grep_line=`echo $line | awk -F : '{print $1}'`
num=`echo $line | awk -F : '{print $2}'`
command_line=`echo $line | awk -F : '{print $3}'`
num_procs=`ps -ef | grep test.prog | grep -v grep | wc -l`
if [ $num_procs -lt $num ]
then
# exeute the program with command_line
# may be send an email to someone that the process is down
fi
Well, it's just a skeleton, that gives the general idea of the script. I checks every line and gets the info it need to check the process and how to execute it if the number of instances is less than it should be.
There are ofcourse more scripting to do, may be send an email, of more complex checks, bt this is the direction.
