Active Directory Performance Monitor - get more details?

In a domain environment, I'm showing periodic spikes in Performance Monitor counter "NTDS\DS Directory Reads/sec", and a couple others for that matter.
However I'm not sure how to get details on what is actually causing the spikes (source computer, user, what have you...)

Is there a way to view a bit deeper rather than just simply seeing a spiky graph?

I'm in 2012 R2 but the domain is 2008 R2 functional levle.

You can enable diagnostic logging on various AD events.

Essentially you will be enabling AD Diagnostic logging, you might want to enable the following objects:

* I would start with basic logging to see which object is returning the information you are looking for, then turn up the logging noise to

1.  Security Events
2.  Directory Access
3.  Garbage Collection

For something like this what you will need to do is use something like WireShark and run this from your domain controller to capture packets from specific AD ports to see where the high volume is coming from.

Another good thing to do is ensure that AD Auditing is enabled as well. This is not enabled by default. I have created a HowTo for setting up and configuring AD Auditing. See my link below...

Active Directory Auditing

Once you have the above configured it should help you find the culprit.

One other thing i would like to mention is that it is possible that you don't have an adequet resources that is servicing your DC (or not enough DC's in your environment). That is also another possibility.
