TCP port monitor setup?

I am currently demoing APM and I'm having trouble figuring out how to monitor something. I need to setup a TCP port monitor and have it notify me when the port is available. So if it does the check and receives a "connection refused" result, then that should be considered an "UP" status. But if it returns an "TCP OK" status, then that should be considered "DOWN" and notify people. I'm currently using Nagios for monitoring, and I am able to configure this type of monitoring. Is this possible in Orion?

Thanks!

This is definitely possible with APM. What are you trying to setup? What part of the configuration are you having trouble with?

I'm trying to monitor some interface ports on one of our servers. This particular system uses TCP ports to connect to other systems. So if I get a connection refused while checking TCP port 59000 on thsi server, that tells me that the link is up and running. But if I get an OK response, then that tells me the link is down and needs to be reset.

I found the place to build the monitor template so that I can specify what ports to monitor. But I'm not finding where to set up what dictates what is considered an UP or DOWN status.

Unfortunately, by design, APM assumes that non-response on a particular port indicates that the application/service is in a down state. Therefore, if you were to use the "Down Application" resource, it would definitely include the application on your server in the list.

On the bright side, alerts can be configured as you see fit. Using the Alert Manager, you would simply define a new advanced alert that would trigger if the status of this application is up.

Thanks for the info. That's surprising that it would be limited to that functionality given the cost.
