in reply to script to monitor and page...

Which OS are you working on?

For Win32, you probably want to look at Win32::Process::Info. For *nix, then you could try Proc::ProcessTable.

Also, there are plenty of off-the-shelf monitoring packages that will do what you want (and a whole lot more). This site lists a whole stack of them. My personal favourites are Big Brother and Nagios. For Win32 systems monitoring, WhatsUp Gold also seems pretty okay.

    Yes. I am aware of BigBrother,Nagios, and Proc::ProcessTable. I was hoping to get ideas on how to keep track if an alert has been sent and if it is sent then don't sent it again. Any idea?

      Well it depends on the solution you choose. It is possible to configure Nagios to do this, see here.

      And I'm pretty sure that Big Brother can also be configured to warn/page only once per alert - but again, check the docs.

      If you were just monitoring a single or a few processes and rolling your own simple monitor using Proc::ProcessTable, then it's just a matter of working out exactly what you want, and then defining a few rules. For example, you may set a flag once an alert goes off and a notification is sent, and then only reset the flag after either the alert goes away, or a certain time has elapsed. Writing a script should be the easy part - it's defining the business rules and getting them right that is the tricky bit :)

      Cheers,
