Using the Telnet Monitor

Telnet is a simple service monitor that checks for a Telnet server on port 23. If no telnet service responds on this port, then the service is considered down.

1. Go to the Active Monitor Library:
   • From the web interface, click GO. The GO menu appears.
   • If the WhatsUp section is not visible, click WhatsUp. The WhatsUp section of the GO menu appears.
   • Select Configure > Active Monitor Library. The Active Monitor Library appears.

     - or -

     From the main menu of the console, select Configure > Active Monitor Library. The Active Monitor Library appears.

   • Click New. The Select Active Monitor Type dialog appears.
   • Select Telnet Monitor from the list, then click OK. The Add Telnet Monitor dialog appears.

     - or -
     Select an existing Telnet Monitor, then click Edit. The monitor properties dialog appears.

   • Name. The name of the monitor as it appears in the Active Monitor Library.
   • Description. The description of the monitor as it appears in the Active Monitor Library.
   • Timeout. Enter a timeout value. This is the length of time in which the service is given a chance to respond. If there is no response in this amount of time, the service is considered down.
