Can I have Netmaster for TCP/IP detect and alert when a LISTENER goes down?
Yes, you can use the NOLISTEN event detector to monitors connection attempt failures due to a listener port not being active.
An event detector defines the network and systems events that you want to monitor, and what to do when the event occurs.
You can define an alert to raise, and you can define the wording of the alert. You can also define an automatic action to run.
Sample event detector definitions are supplied. Each type of event is represented in the samples. Use these definitions as examples when you create your own event detectors.
The above can be found in the Configuring Event Monitoring section in the Netmaster for TCP/IP Implementing manual.
