Monitoring the DHCP Pool

We exhausted a DHCP pool and had a resulting outage from it. 

Has anybody written powershell to retrieve the pool to enable monitoring?  Is this even possible?

Thanks in advance,

Hey, Rob!

I did a spot of Googling and managed to find this:

It specifically calls out Win2k3, but I suspect the counters haven't changed much since then.  It should be easy enough to run a typeperf on the DHCP server to see what counters are exposed by more modern versions of Windows Server.

Based on the article, some promising counters to threshold against might be:

DHCP Server\Nacks/sec
DHCP Server\Conflict Check Queue Length
DHCP Server\Declines/sec

Naturally, you'll want to confirm that those counters are still available 18 years later before you start building thresholds.

I hope this helps!
