Syslog
VMware Web Service SDK (API)

18. Choose a monitoring tool
System Center Operations Manager
Best of breed for Windows OS and Apps
Integrate VMware to see end-to-end

19. Key concepts for monitoring virtualization
You need a map
Track 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-resolution

20. 1. Map - Storage topology view
Map VMs and Apps to the storage they depend on

21. 2. Visualize - Storage heatmaps
Graphical views of Datastore usage and performance
Click and drill-down into the ‘hot spots’

22. 3. Sharing – Memory Pressure Dash
Relate Host memory pressure to VM memory consumption, and view in-context alerts

23. 4. Futures - Capacity Planning Reports
For Clusters and Storage
Forecast resource limits
Predict capacity and plan for growth

24. 5. Knowledge base

25. 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 - 8

26. Key metrics : Over-commitment
CPU Pressure
Memory Pressure
Memory allocated versus physical RAM available
vSphere shares very efficiently (TPS) – but:
High values can cause ballooning, or even swapping

27. Key metrics : Over-commitment
CPU Pressure
Memory Pressure
Memory allocated versus physical RAM available
vSphere shares very efficiently (TPS) – but:
High values can cause ballooning, or even swapping

28. Key metrics : Over-commitment
CPU Pressure
Memory Pressure
Disk Pressure
Disk space allocated versus capacity
No real performance impact – but:
If VMs start to use their allocation – physical capacity can fill quickly

29. Key metrics : Compute CPU
CPU Usage
CPU Used, <90%
CPU Ready, <15%
CPU Co-Stop, <15 %
Relate Host usage to VMs usage

30. 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 usage

31. 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 Datastores

32. Key metrics : Storage Storage space Storage Latency
Kernel Latency within Host ~0ms
Device Latency on backend <20ms
Find the hotspots of high I/O
Relate VMs to Datastores

33. Key events: Availability and configuration
Availability and Status
VMs
Hosts
Storage
Network
Hardware
