There is a UNIX command for checking
process status, ps.� PS is in all UNIX but the output can vary.� The example
below is for HP-UX 11i.
The command "ps -ef | grep <your
process name here>" would return something like this:
$ ps -ef | grep hcimonitord
� 1675 ?������� 402:20 hcimonitord
The number "1675" is the process
ID.� The 402:20 is the duration the process has been running.
So, create a script
vi <your script name>
#! /usr/bin/ksh
# Purpose check to see if hcimonitord is
running
# get the process status from UNIX
psValue=$(ps -ef
| grep hcimonitord)
if [ $psValue = "" ] ; then
�� echo hcimonitord is not in memory
�� echo "Subject: HCIMONITORD
ERROR\\n\\nProcess is not in memory;" | sendmail ME
fi
pidValue=$(echo $psVal|awk '{print $1}')
RunningDurationBefore=$(echo $psVal|awk '{print
$3}')
Sleep 60
RunningDurationAfter=$(echo $psVal|awk '{print
$3}')
if [ $RunningDurationBefore -eq $RunningDurationAfter
] ; then
�� # if the duration the process has been running is
equal
�� # before and after the 60 second sleep, it's
not seen as running.
�� echo hcimonitord is not running
�� echo "Subject: HCIMONITORD
ERROR\\n\\nProcess is in memory but not running;" | sendmail ME
fi
exit 0
## end of script
make your script executable
�� chmod +x <your script name>
Add your script to crontab;
� crontab -e
0,5,10,15,20,25,30,35,40,45,50,55 * * * * <your
script name with path>
If you are not allowed to run crontab, then you have
to get the system admin to set up the cron or allow you to run cron.
The 0,5,10,15... tell the cron to run
every 5 minutes, you can change that to however frequent you want.
Good Luck,
Tom Gendron

Monitoring UNIXProcesses
At this time, we wish to receive an alert when one Unix
process is down.
We
have no idea about the script you meant, have an example of that script ?
Once
it run, this script will generate a snmp trap when a monitored process down,
isn't it ? pls correct me if I'm wrong.
rgrds,
Arief

Monitoring UNIXProcesses
|
I have to ask the same question I asked earlier in
this thread.
What do you mean by "monitor"? What do you want What's Up Gold
to do?
You could monitor processes to see if they die using the scripting I
mentioned earlier in this thread.
You could monitor and graph CPU usage and memory of processes using
hrSWRunPerfCPU.
>Would you pls inform us what we should have (and do) to be able to monitor
Unix processes ?
>>As processes spawn and die (whether through SIG_TERM or other means),
the OIDs are going to change. The end result is that I don't have a
consistent entity to monitor that guarantees the associated process is
what I expect.
