How to monitor Active Directory replication partners

Please keep in mind that by default the PRTG Probe Service uses the "SYSTEM" account to perform monitoring tasks. Could it be that your commands do not work for the SYSTEM account (it does not allow UI for EXEs)

For monitoring we use an Active Directory account. This account is member of Domain Admins.

PTF ADSReplFailures

With Custom Sensor PTF ADSReplFailures you can check your domain controllers for replication errors.

This sensor gets the number of replication errors reported by the domain controllers.

-u=username -p=password|passhash -d=domain name

-u=username        The name of the user account that can access the domain replication
-p=password        The password or passhash(*) of the user account that can access the domain replication  
-d=domain name     The Full Qualified Domain Name.

The Custom Sensor can be downloaded from this page.

Thank you Gerard for your time to create a Custom Sensor for my request. Unfortunately I get "Replication access was denied" when using this sensor.

Hi Martin,

This is fixed in version 1.0.2 of the sensor.

I added parameters for username and password of an account that has access to the AD replication.

Also running the sensor from a cmd window will give you information now on what domaincontroller reported an error.

This is a couple of months old now, but I have a script which you might find useful, too. Basically, it's a vbs script which uses the output of DCDIAG to determine if AD is functioning correctly. It's based off a Nagios script, and it seems to work quite well. If you are interested I'll see if I can send it to you.
