![]() ![]() Once you have created the Data Collector Set go into the Properties of it and make sure the Alerting threshold and Sample Interval is set properly for each Performance Counter. The LSASS process has exceeded the processor utilization threshold over multiple samples. Create a new Data Collector Set Add whichever Performance Counters you would like to monitor and set the Alerting threshold. Microsoft.PerformanceEssentialServices.AggregateMonitor This allows you to see what processes are waiting for a resource that is being used by another process. ExternalĬapacity Planning for Active Directory Domain Services One of the new options added into Task Manager in recent versions was the Analyze Wait Chain option when you right-click on a task in the Details view. View the overall system performance of the machine to determine if it needs additional resources.Īdd additional domain controllers to help load-balance the load.Įnsure that there are a sufficient number of DCs in the active AD sites. The domain controller is under a denial-of-service attack. The domain controller is critically low on memory. This is usually caused by inefficient, CPU-intensive operations such as non-indexed queries. One or more other domain controllers failed, and their load transferred to this domain controller because it is now the closest available domain controller.Īn application is placing a heavy load on the domain controller. The domain controller is a primary domain controller (PDC) emulator operations master, and there are either a large number of password lockouts or a large number of expired user accounts. 8 Answers Sorted by: 32 Windows Performance Monitor (perfmon) should do the job for you you can configure it to log to a file, so just enable the counters you need and itll log as much as you want. The domain controller is a bridgehead server, and it is compressing large amounts of data because a bulk load must be replicated inter-site. To monitor resource usage and server processes, you can use Windows Performance Monitor (PerfMon), which is included with Windows Server. If the overall CPU utilization on the server is too high, users and services that rely on Active Directory Domain Services may experience delays. The core process (lsass.exe) for Active Directory Domain Services is consuming a lot of CPU resources.
