Linux Unix Print Queue Monitor - LPR port Monitor

Stealthn

Hi,

 

I've had a request to monitor both port 9100 on a printer and Linux print queues for jobs building up. I have tried a generic TCP port monitor in APM but it fails and I am guessing it fails because when connecting to 9100 of the printer, the printer accepts the connection but does no provide a response.

Is there anyway I can monitor a port for availability even if the port does not give a response code? I guess I could setup a job to telnet to the port and watch for a connection refused response and assume it's down then, but it seems that Orion APM should be able to do this as I can do it with freeware.

The second part of the equation is to monitor a Linux print queue and alarm if there are X jobs in the queue indicating that it's not sending to the printer. I know I could set something up on each linux system, but this seems like a lot of work when the Orion APM should be able to do this.

 

Any thoughts?

 

Thanks,

Bob

You should definitely be able monitor port 9100 with the TCP port monitor. As I understand it, it simply tests for connectivity with no regard for the response code. If it can connect, the monitor should up and if not, it should show as down. I actually tested this and it's working for a TCP port 9100 monitor that I assigned to a printer.

Regarding the second part of your question, if you know the OID that reports on the number of jobs in a Linux printer queue, you could configure a UnDP to monitor that. If not, perhaps you could create a perl script that would query the Linux host for this information.
