DHCP Performance Monitoring
If you really want to get a feel for your DHCP server, then I recommend
creating a performance log and monitoring the DHCP traffic to and from your server.
I have two confessions to make.
1) I love performance monitoring, I rarely miss a chance to create logs, add
counters and then analyze what is happening on the network. Performance monitor not only troubleshoot problems, but also teaches you about how DHCP works.
2) While DHCP monitoring is fascinating, it is more important to analyze the
big 4 objects: memory, processor, disk and network. That said, why not add these
network counters when you monitor those 'big 4' counters.
I have selected the key counters to monitor DHCP activity. In addition
for checking for bottlenecks, these counters will help to reinforce your DHCP
knowledge.
 Learn more about DHCP. As an MCT trainer, I can thoroughly recommend TrainSignal
because they provide practical hands on training. In particular, I like the way TrainSignal cover all learning methods, instructor lead, video and of course text
material. With TrainSignal you can either take one module, for example DHCP or go for a combination of modules.

Performance Counter
DHCP Server Object |
How it helps |
Packets Received / sec |
Surge of activity could alert you to a problem on the
network |
Requests / sec |
Detect 'rush hour' |
Active queue length |
Value of greater than 2 could indicate a bottleneck. |
Duplicates dropped /sec |
Could mean that more than one Relay Agent is forwarding
requests. |

Summary
Monitoring DHCP traffic will help you learn about the DHCP process.
Performance logs will either confirm that your server is healthy, or else alert
you to network bottlenecks.
