SMTP Port Check component fields

You may configure the following boxes for the SMTP 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.
