PRTG Network Monitor:
Active Directory monitoring software
A functional Active Directory is one of the core elements in a network’s organization.
Virtually every company with a Windows infrastructure uses Active Directory to manage network resources and regulate access rights within a domain and its domain forest. The Active Directory creates a directory service, which stores information relating to a network's resources and objects.
In addition, domain controllers – usually several within a single domain – are used to store data sets regarding objects.
A replication service ensures that all of a domain's directory information is always and fully available on all of its domain controllers.

iWhat is a sensor?
In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Preventing Replication Errors
The first problem involves so-called replication errors. The replication of directory data between various domain controllers can be prone to error. In turn, the resulting errors can cause problems with authentication and with access rights to resources.
A variety of factors play a role in the occurrence of these errors, including the number of consecutive synchronization failures, the time of the last synchronization attempt, and the number of pending replication operations.
The PRTG sensor Active Directory Replication Errors monitors up to eight different parameters during the replication of directories and the synchronization of the various domain controllers, and intelligently sounds the alarm in the event of anomalies or errors.
Identifying logged-out and deactivated users
Another common problem associated with the use of an Active Directory involves logged-out or deactivated users. Maintaining an overview of such users is next to impossible with standard AD tools.
With PRTG, you’ll get a ready-to-use script for PRTG Network Monitor which searches the Active Directory for all logged-out and deactivated users, and then lists them in PRTG: https://kb.paessler.com/en/topic/57603-is-it-possible-to-monitor-active-directory-user-account-status
To use this script, PRTG requires the Active Directory PS module. A manual with information on how to install the module can be found here: Microsoft Manual.
With a Search-AD account, you can run the script with a number of different queries. For the switches, see Microsoft’s TechNet platform: TechNet Platform
Monitor AD Group Membership
Using a PRTG script, you can enumerate how many people are in a group and then set up channel limits to put the sensor into an error status when the number of members exceeds the intended amount.
If you want to know if someone joins an AD group like Domain Admins and get a notification when this happens: https://kb.paessler.com/en/topic/62616-can-i-use-prtg-to-monitor-ad-group-membership
PRTG immediately recognizes replication errors and
logged-out users and sends intelligent alerts.
Overview: Active Directory Replication Errors Sensor
iActive Directory (AD) is a directory service created by Microsoft for use in a Windows Server environment. It provides authentication and authorization functions, as well as providing a framework for other such services. The directory itself is an LDAP database that contains networked objects.
PRTG uses the Windows credentials of the parent device to check the domain controller for replication errors.
The Active Directory Replication Errors sensor displays the following in PRTG:
- Number of consecutive synchronization errors
- If the source was deleted
- If the scheduled synchronization was disabled
- Time of the last synchronization attempt
- Result of the last synchronization
- The last time a synchronization was successful
- Number of aligned synchronization sequences
- Number of pending replication operations
