monitoring multiple jobs Unix

vikram3.r · #1 (**permalink**) 10-08-2009

I have a list of jobs. their expected start time and their expected duration.

my needs are

monitor multiple jobs (starting at different time and their execution time also differs)
Need to mail if any of the job running longer than its expected duration.

Whats the efficient way to scripting & scheduling to monitor the script..??

I would make a wrapper script that would do the following:

Code:

Set a trap for child exit
On child trap, exit because we didn't exceed time

Get commmand and time from command line
execute command in background 

while time < expected
 sleep short time (1 minute?)
 if command not running then exit
end while

Email alert

You don't want to sleep in a shell for the expected time because you won't get the child exit trap until you wake up if the monitored command exited earlier.
