SCOM Hyper-V Management Pack Extensions
If you’ve ever been responsible for the management or monitoring of a Hyper-V virtualization platform, you’ve no doubt wanted and needed to monitor it for performance and capacity. The go to choice for monitoring Hyper-V is System Center Operations Manager (SCOM) and if you are using Virtual Machine Manager (VMM) to manage your Hyper-V environment then you could have and should have configured the PRO Tips integration between SCOM and VMM.
With all of this said, both the default SCOM Hyper-V Management Pack and the monitoring improvements that come with the VMM Management Packs and integration are still pretty lacklustre and don’t give you all the information and intelligence you would really like to have.
Luckily for us all, Codeplex comes to the rescue with the Hyper-V Management Pack Extensions. Available for SCOM 2012 and 2012 R2, the Management Pack provides the following (taken from the Codeplex project page):
New features on release 18.104.22.1682
Support for Windows Server 2012 R2 hyper-V
Hyper-V Extended Replica Monitoring and Dashboard
Minor code optimizations
Features on release 22.214.171.124
VMs Integration Services Version monitor
Hyper-V Replica Health Monitoring Dashboard and States
SMB Shares I/O latency monitor
VMs Snapshots monitoring
Management Pack Performance improvements
Included features from previous release
Hyper-V Hypervisor Logical processor monitoring
Hyper-V Hypervisor Virtual processor monitoring
Hyper-V Dynamic Memory monitoring
Hyper-V Virtual Networks monitoring
NUMA remote pages monitoring
SLAT enabled processor detection
Hyper-V VHDs monitoring
Physical and Logical Disk monitoring
Host Available Memory monitoring
Stopped and Failed VMs monitoring
Failed Live Migrations monitoring
The requirements to get the Management Pack installed are low which makes implementation really easy. If you keep your core packs updated there is good chance you’ve already got the three required packs installed, Windows OS 6.0.7061.0, Windows Server Hyper-V 6.2.6641.0 and Windows Server Cluster 6.0.7063.0.
The project suggests there is documentation but it seems to be absent so what you will want to know is what is the behaviour going to be upon installation? If you have a development Management Group for SCOM then install it here first to test and verify as you should always be doing. The Management Pack is largely disabled by default which is ideal but there are a couple of rules enabled by default to watch out for so check the rules and change the default state for the two enabled rules to disabled if you desire.
As is the norm with disabled rules in SCOM, create a group which either explicitly or dynamically targets your Hyper-V hosts and override the rules for the group to enable them. The rules are broken down into Windows Server 2012 and Windows Server 2012 R2 sets so you can opt to enable one, the other or both according to the OS version you are using for your Hyper-V deployments.
If you do have the VMM integration with SCOM configured and you are using Hyper-V Dynamic Memory, you will notice very quickly if you enable all the rules in the Hyper-V Management Pack Extensions that you will start receiving duplicate alerts for memory pressure so make a decision where you want to get your memory pressure alerts from be it the VMM Management Pack or the Hyper-V Extensions Management Pack and override and disable alert generation for the one you don’t want.
There is still one metric missing even from this very thorough Hyper-V Extensions Management Pack and that is the collection of the CPU Wait Time Per Dispatch performance counter, the Hyper-V equivalent of the VMware vSphere CPU Ready counter. I’ll cover this one in a later post with a custom Performance Collection Rule.
