Monitor Active Directory Logs with EventLog Analyzer

Active Directory forms the core part of the Microsoft Windows domain administration. It is a very critical component, as the failure of it may disrupt the entire network. When the directory service fails, the details are promptly recorded in the logs. If the logs are analyzed thoroughly, the root cause of the failure can be found. Any operation on the Active Directory objects has to be captured. The Active Directory operations on directory service object and replica source naming context directly affects the user accesses and operations of machines in the network. Thus, monitoring Active Directory log events is critical to ensure smooth functioning of networks.

EventLog Analyzer can monitor Active Directory logs and any specific failure incident can be tracked in real-time. With this, it can alert the network administrator instantly, so that remedial measures can be taken swiftly to avoid network failure.
