Active Directory, also known as the central nervous system of IT infrastructure, plays a key role in the controlling of critical resources and sensitive assets within an organization’s network.

With the continuing rise in both the number and variety of attacks against technology as the years progress, the need for effective protection is vital.

The consistent and ongoing monitoring of Active Directory becomes crucial in this task, aiding with the fast and efficient identification of unauthorized changes. Active Directory further grants system administrators the ability to keep track of how it is protecting the resources on the organization’s network.

This ensures the network is running safely, while also preventing the interrupted workflow of users required to perform their daily duties.

Active Directory also assists in the structuring of the hierarchy of an organization’s network, identifying which computers belong on which network, user access to resources as well as their restrictions and more. This, in combination with proactive and systematic monitoring, ensures continuous, seamless service delivery in large environments with multiple domains, domain controllers or physical sites.

The importance of monitoring increases as networks grow and the scalability of Active Directory is utilized. With the aim of reducing network related issues, such as data replication failures, insufficient disk space and the ceasing of critical applications, active change management supports system administrators in the quick detection of potential issues. While possibly small at first, they can easily spiral into network-wide problems if not sorted out, creating situations where lengthy troubleshooting negatively affects the network and the organization’s productivity.

This process of change management involves two core components, change administration and change monitoring. The first focuses on policy-based administration, change analysis and the automation of tasks, while the second allows for centralized auditing, real-time change detection and readily understandable reports.

While Active Directory can be monitored though Microsoft’s built-in System Center Operations Manager, the addition of third-party monitoring tools allows for broader monitoring capabilities. These tools, through their access to Microsoft libraries and the collection of performance counters, help system administrators to both monitor and obtain optimal performance and health of the service directory.

These tools further allow for overall insight and visualization into the statistics related to the Active Directory environment, with the data gathered displayed through central dashboards, graphs and reports. When abnormal behavior is detected, such as performance drops or unauthorized access, alerting systems are capable of notifying system administrators immediately, cutting their response time immeasurably.

When it comes to the monitoring of Active Directory, the use of third-party tools and their ability to automate tasks notably improves the efficiency of the monitoring capabilities of system administrators.

With highly effective security and a stable network being a staple requirement in organizations across the world, the following Active Directory monitoring tools will greatly assist in achieving these goals.
