Monitor Internet Application

Applies To: Opalis 6.3

The Monitor Internet Application object will trigger a Policy when an internet application server becomes unavailable or becomes available. You can monitor an FTP, Web, Email (POP or SMTP), or DNS server using the Monitor Internet Application object. Depending on the type of server that you are monitoring you will need to specify different configuration information. This object uses a satellite license.

The Monitor Internet Application object can be used to make sure your external FTP or Web servers are reachable through the internet and then automatically restart the server if it is found to be unavailable.
