PATROL for Exchange Servers 2003 monitors the front-end servers in your environment. A front-end server accepts requests and forwards them to back-end servers for processing. A front-end server typically only processes requests for protocol servers such as Outlook Web Access Server, POP3, and IMAP.
When you install PATROL for Exchange Servers on a front-end server, certain application classes and parameters are deactivated because monitoring these features on a front-end server is unnecessary.
The following application classes are not monitored on a front-end server:
MSEXCH_RoundTrip_Client
MSEXCH_RoundTrip_Container
MSEXCH_RoundTrip_InetServer
MSEXCH_RoundTrip_Server
MSEXCH_Top_Consumers
MSEXCH_Top_Folders
MSEXCH_Top_Mailboxes
MSEXCH_Top_Receivers
MSEXCH_Top_Senders
MSEXCH_Watched_Users
If you selected the Manage Microsoft Exchange Mail Servers option during installation, these application classes and the parameters they monitor will not be monitored.
