Upon discovery of Domain Controllers, OpManager automatically associates the Active Directory monitors to the server and starts monitoring for performance and availability. Every monitored parameter is mapped with industry best-practiced thresholds by default. You can start with these thresholds and later tweak to suit your AD monitoring requirements.

Active Directory Monitoring - Monitor Active Directory Services

Active Directory depends on certain critical services for proper operation.The first step in ensuring Active Directory availability is to monitor these critical services.

Active Directory Monitor monitors the following critical services

  • Server Service that enables the computer to connect to other computers on the network based on the SMB protocol.
  • File Replication Service that maintains file synchronization of file directory contents among multiple servers.
  • DNS Client service that resolves and caches DNS names.
  • Security Accounts Manager Service that signals other services that the Security Accounts Manager subsystem is ready to accept requests.
  • Intersite Messaging Service that is used for email-based replication between sites.
  • Kerberos Key Distribution Center Service that enables users to log on to the network using Kerberos version 5 authentication protocol.
  • Net Logon Service that supports pass-through authentication of account logon events for computers in a domain.

When any of these services become unavailable, your Active Directory Server will not be able to perform critical tasks properly.
