Echo Port Check component boxes

You may configure the following boxes for the Echo Port Check component:

Name. Enter a unique name for the component.
Description. (Optional) Enter additional information about the component.
Critical. Click to select this check box if the component is critical.
Note: 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.
Polling frequency. Select a time (in minutes or hours) you want APM to wait between polls.
Protocol. 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.
Port number. Enter the port number that you want to monitor.
Polling timeout. 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.
Script to Run. Enter your script using as many Send, Expect, SimpleExpect, and Flow Control keywords as you want. For more information, see Script Syntax.
Expect. (Optional) Click to open the Rules Expression Editor and test a string of text for particular patterns.
