Monitoring with PowerShell: Monitoring Active Directory replication

Kelvin Tegelaar | 11 Nov, 2019 | 1 Mins Read

I’ve often deployed domain controllers in environments that weren’t the most stable due to connectivity issues. To make sure that the domain controllers keep replicating correctly and we detect issues early we use the Active Directory cmdlets in combination with our RMM system. This makes it so we can monitor the current status of the replication and alert if it does not work for a longer period of time.

The script is suitable for server 2012R2 and up. You can use this in your RMM system to detect issues early. I like monitoring when the replication has not worked for 6 hours, but you can always change this to your own preference.

Active Directory Replication Monitoring

$AlertTime = (get-date).AddHours(-6)
$FailedArr = @()
$RepStatus = Get-ADReplicationPartnerMetadata -Target * -Partition * | Select-Object Server, Partition, Partner, ConsecutiveReplicationFailures, LastReplicationSuccess, LastRepicationResult
foreach ($Report in $RepStatus) {
    $Partner = $Report.partner -split "CN="
    if ($report.LastReplicationSuccess -lt $AlertTime) {
        $FailedArr += "$($Report.Server) could not replicate with partner $($Partner[2]) for 6 hours. please investigate"
    }
}
if (!$FailedArr) { $FailedArr = "Healthy" }

And that’s it for today! as always, Happy PowerShelling.

CyberDrain CTF returns! (and so do I!)

It’s been since september that I actually picked up a digital pen equivalent and wrote anything down. This was due to me being busy with life but also my side projects like CIPP. I’m trying to get back into the game of scripting and blogging about these scripts. There’s still so much to automate and so little time, right? ;)

Intro

This is a monitoring script requested via Reddit, One of the reddit r/msp users wondered how they can monitor Acronis a little bit easier. I jumped on this because it happened pretty much at the same time that I was asked to speak at the Acronis CyberSummit so it kinda made sense to script this so I have something to demonstrate at my session there.

Intro

Wow! It’s been a while since I’ve blogged. I’ve just been so swamped with CIPP that I’ve just let the blogging go entirely. It’s a shame because I think out of all my hobbies it’s one I enjoy the most. It’s always nice helping others achieve their scripting target. I even got a couple of LinkedIn questions asking if I was done with blogging but I’m not. Writing always gives me some more piece of mind so I’ll try to catch up again. I know I’ve said that before but this time I’ll follow through. I’m sitting down right now and scheduling the release of 5 blogs in one go. No more whining and no more waiting.
