Why System Center 2012 for
VMware
(01) Private cloud and Service Deployment
(02) VMware is widely deployed Hypervisor
(03) End to End Monitoring for VMware and Microsoft workloads
(04) Heterogeneous Hypervisor Management and Automation
(05) System Center 2012 is
THE management product for Microsoft
based workloadsSlide10

key concepts for monitoring virtualization
You need a mapTrack relationships & dependencies
Visualize as you virtualize
Dashboards & Reports. Context is key
Everybody has to share
Understand resource sharing and over-commitment
Look to the future
Use forecasting, trending, modelling
Knowledge is power
KB guidance is essential for lower time-to-resolutionSlide13

Key metrics : Compute CPU
CPU Usage
CPU Used, <90%CPU Ready, <15%CPU Co-Stop, <15 %
Relate Host usage to
VMs
usageSlide17
Key metrics : Compute Memory
Memory Usage
Memory Used, <90%Memory Balloon, <50%
Can cause high disk I/O in-VM due to paging
Memory Swapping, = 0!
Swapfile
use is last resort for the Host
Relate Host usage to VMs usageSlide18
Key metrics : Storage
Storage space
Disk Pressure is a factor!Minimum free space >100 MB
At this point VM corruption will occur
Also track ‘garbage/unknown’ files
Also track Snapshots
Relate VMs to
DatastoresSlide19
Key metrics : Storage
Storage spaceStorage Latency
Kernel Latency within Host ~0ms
Device Latency on backend <20ms
Find the hotspots of high I/O
Relate VMs to
DatastoresSlide20

Key metrics : Over-commitment
CPU Pressure
# of running VM
vCPU
per Host Core
High ratio can impact vSphere CPU Scheduler
Absolute maximum = 25
Best practice 4 - 8Slide23
Key metrics : Over-commitment
CPU PressureMemory Pressure
Memory allocated versus physical RAM available
vSphere shares very efficiently (TPS) – but:
High values can cause ballooning, or even swappingSlide24
Key metrics : Over-commitment
CPU PressureMemory Pressure
Disk Pressure
Disk space allocated versus capacity
No real performance impact – but:
If VMs start to use their allocation – physical capacity can fill quicklySlide25
