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 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
When any of these services become unavailable, your Active Directory Server will not be able to perform critical tasks properly.
Domain controller roles perform specific functions in an Active Directory environment. These specialized roles include PDC Emulator, Infrastructure Master, RID Master, Domain Naming Master, and Schema Master. OpManager's Active Directory Monitor does a good job of identifying the roles assigned to the server in the network.
Active Directory Add-on monitors CPU, Memory and Disk Space utilization as well as Processor Queue length using WMI. Operators can get both real-time and historical statistics for CPU, Memory and Disk Utilization. Using customizable thresholds, operators can be notified well in advance and thereby proactively prevent outages before they occur. You can also see the number of processes and services that are active on the system.
Active Directory Add-on monitors the usage of critical LSASS & NTFRS processes. Parameters monitored include CPU Usage, Physical RAM, File Reads, File Writes, Cache Hits, etc. You can also monitor critical Network counters like Connected Users, LDAP Client Sessions, & LDAP Bind Time as well as Performance Counters like NTLM Authentication, Kerberos Authentication & LDAP Searches.
