Adding and editing a 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.

To add a new Telnet active monitor:

1. From the WhatsUp Gold web interface, go to Admin > Monitors. The Monitor Library dialog appears.
2. Click the Active tab. The Active Monitor list appears.
3. Click New. The Select Active Monitor Type dialog appears.
4. Select Telnet Monitor, then click OK. The Add Telnet Monitor dialog appears.
5. Enter or select the appropriate information:
   • Name. Enter a unique name for the active monitor. This name displays in the Active Monitor Library.
   • Description. Enter additional information about the monitor. This description displays next to the monitor in the Active Monitor Library.
   • Timeout. Enter the length of time WhatsUp Gold attempts to connect to the selected device. When the time you enter is exceeded without connecting, a timeout occurs and WhatsUp Gold stops trying to connect to the SMTP server. This is considered a failed connection.
   • Use in Rescan. Select this option to have the monitor appear in the Active Monitor list on the Device Properties dialog. WhatsUp Gold adds the monitor type to the device during a rescan, which is launched using the Rescan button on the Device Properties dialog, if the protocol or service is active on the device.
6. Click OK to save changes.
7. After configuring an active monitor in the Active Monitor Library, add the monitor to devices.
