Network Port Check
The Network Port Check component allows you to create a script to run on a specific device that monitors a designated TCP, UDP, or SSL network port. There are a number of options for this component type depending on the communication protocol you want to use to monitor the port:
Configure the following boxes for the Network Port Check component:
- . Enter a unique name for the component.
- . Enter additional information about the component.
- . Click to select this check box if the component is critical.
: Components specified as critical cause the application to go into a down state when the component is out of threshold. Non-critical components cause the application to go into a warning state. For more information on application states, see Working with application states.
- . Select a time (in minutes or hours) you want APM to wait between polls.
- . Select TCP, UDP, or SSL from the list. 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.
- . Enter the port number that you want to monitor.
- Enter the length of time APM attempts to connect to the selected device. When the time you enter is exceeded without connecting, a timeout occurs and APM stops trying to connect to the device. This is considered a failed connection.
- . Write your script using as many
Send, Expect, SimpleExpect, and Flow Control keywords as you want. For more information, see Script Syntax. - . (Optional) Click to open the Rules Expression Editor and test a string of text for particular patterns.
