Active Directory monitors the size of its database in order to make sure that it does not grow too large, and thus prevent potential system performance issues. This article will show you how easy it is to create your own Active Directory monitor using PowerShell by building a small script.
Active Directory Database Size Monitoring: Building a Monitor is a blog post that explains how to build a monitor for the size of your Active Directory. The blog post includes detailed steps on how to do this and also includes screenshots.
The Active Directory database is the most critical component of AD. After all, AD wouldn’t be much use without the database. Where is the database for Active Directory? What is the location of ntds.dit? And how do you keep track of the database? This lesson will teach you the answers to these questions!
It’s critical to keep an eye on all parts of AD, and the database in particular. This is why it’s well worth the effort to figure out what the database is made up of and how to effectively manage it to keep it in good shape.
In this post, we’ll create a PowerShell script that enables you to query each AD database on each DC in your domain and ascertain one key database metric: the aggregate database size.
Ntds.dit (The Active Directory Database)
An AD database is made up of a file named ntds.dit, which is normally found under C:WindowsNTDS on each domain controller.
To guarantee that we acquire the correct route, we must first determine the database path. The registry entry HKLM:SystemCurrentControlSetServicesNTDSParameters stores this value.
Using PowerShell to locate the AD Database
Let’s look for the database file path on all of the DCs in our environment.
$dcs = (Get-ADDomainController). Name Invoke-Command -ComputerName $dbs -ScriptBlock $dcs Select PSComputerName,’DSA Database File’ from Get-ItemProperty -Path HKLM:SystemCurrentControlSetServicesNTDSParameters |
I can now query each of the current sizes since I know the route to the Active Directory database on each DC. To do this, I’ll use a foreach loop to run over the $dbs variable I defined earlier, which includes the domain controller name as well as the path to the database file for each.
The Size of the AD Database is Being Monitored
To make the output more understandable, I’ll create a $output hashtable and attach values to it as I read each database file, such as the domain controller name and database size. When I’m done reading the database file, I’ll transform this to a custom object. This will provide a more appealing result than just PSComputerName, DSA Database File, and the size.
$output = @ $dbs | foreach $output $path =

This snippet will provide a lovely DatabaseSizeDB output as well as a DomainController attribute. I just have one DC in my demo setting. If you were running this in production, each of your domain controllers would be included, along with the overall database size in GB.
You now have a script that you can execute at any moment to receive a snapshot of how much each of your Active Directory database files has grown.

The “minimum requirements for active directory server” is the minimum requirements that must be met before an Active Directory (AD) server can start monitoring its database size. This will help you to monitor your AD database size and keep it under control.
