About the Exchange Server 2010 database agent
The Symantec ApplicationHA database agent for Microsoft Exchange 2010 provides monitoring support for Exchange 2010 databases. The agent monitors the Exchange 2010 mailbox databases, brings them online, and takes them offline.
The agent also starts the following Exchange services if they are not running already, and monitors their status:
Microsoft Exchange AD Topology service (MSExchangeADTopology)
This service provides Active Directory topology information to the Exchange services. If this service is stopped, most Exchange services cannot start.
Microsoft Exchange Replication Service (MSExchangeRepl)
This service provides replication functionality for Mailbox Server role databases and is used by Local Continuous Replication (LCR) and Cluster Continuous Replication (CCR).
Microsoft Exchange System Attendant (MSExchangeSA)
The Exchange component responsible for monitoring, maintenance, and Active Directory lookup services, and ensuring that operations run smoothly.
Microsoft Exchange Information Store (MSExchangeIS)
The Exchange storage used to hold messages in users' mailboxes and in public folders.
Microsoft Exchange Mail Submission (MSExchangeMailSubmission)
This service submits messages from the Mailbox Server to the Hub Transport Server.
The agent internally monitors these services; the Exchange 2010 application monitoring configuration does not contain separate resources for these services.
