TCP/IP Monitor

The TCP/IP monitor is used to monitor a TCP/IP service that either does not appear in the list of standard services or uses a non-standard port number.

• 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.
• Network type. Select either TCP, UDP, or SSL from the pull-down menu. The network type for the FTP (File Transfer Protocol) service is TCP; the network type for the RADIUS (Remote Authentication and Dial-In User Service) service is UDP. The HTTPS monitor uses the SSL type.
• Port number. Enter the TCP or UDP port that you want to monitor.
• Timeout. Amount of time (in seconds) WhatsUp Gold should wait for a response to a poll.
• Script. Write your script using as many Send, Expect, SimpleExpect, and Flow Control keywords as you would like. For more information, see Script Syntax.
• Expect. Opens the Expression Editor. Whatever is placed here appends to the end of the script.
• Use in discovery. Select this option to have the monitor appear in the Active Monitors list during discovery. From there, you can select the monitor to have WhatsUp Gold discover that monitor type on your devices.
