Don't forget to handle connection attempts that hang and never return.

        Subject:        RE: SLA Trigger/Procedure

I agree what is needed is something very generic that could monitor the uptime of pretty much any process. After giving this more thought and always liking to keep things simple here is the direction I might eventually
head. The logic below would result in a log file that shows all unscheduled
outage periods. You would have to ensure it runs at regular intervals.

(NOT VERY PRETTY, BUT SIMPLE ENOUGH) Files Required:

Control file that has crontab like entries which define periods that are either outages or times when database is expected to be running.

Script Workings:

Run command/script which returns 0 or 1 (0=thingy not running, 1=thingy running) use separate command/script to log into database, grep for process etc...

If (( 0 ))

check control file to see if thingy should be running if suppose to be running

store time & trigger flag (cat time to flag file) if not suppose to be running

       if flag
          unscheduled outage was triggered but has rolled into an

scheduled
outage period

          log start and end time for outage
          reset flag
       fi

fi
else

if flag

      thingy is back up
      log start and end time for outage
      reset flag

fi
fi
