  1. Keeping Hyper-V Healthy Brien Posey http://www.backupacademy.com Brien@brienposey.com Twitter: @BckpAcademy

  2. About Me • Freelance technology author and eleven time Microsoft MVP • Formerly worked as CIO for a national chain of hospitals and healthcare facilities • Served as a network engineer for the DoD at Fort Knox • Worked as a network administrator for some of the country’s largest insurance companies

  3. Keeping Hyper-V Healthy • Hyper-V requires routine monitoring and maintenance to remain healthy. • Two common tasks are: • Resource metering • Patching

  4. Resource Metering • Resource monitoring is used to prevent a host from being overloaded and for future capacity planning, but that’s just the beginning. • Applications tend to span multiple VMs • If you want to know about application resource consumption, you must examine the related VMs collectively. • The same principle also applies to departmental chargebacks.

  5. Hyper-V Resource Metering • Average CPU usage, measured in megahertz over a period of time. • Average physical memory usage, measured in megabytes. • Minimum memory usage (lowest amount of physical memory). • Maximum memory usage (highest amount of physical memory). • Maximum amount of disk space allocated to a virtual machine. • Total incoming network traffic, measured in megabytes, for a virtual network adapter. • Total outgoing network traffic, measured in megabytes, for a virtual network adapter

  6. Resource Metering • Live (or offline) migrations do not impact resource metering. • Windows Server 2012 R2 adds network metering port ACLs. This allows differentiation between internal network traffic and external network traffic for billing purposes. • Resource metering must be enabled before it can be used.

  7. Per Host Metering • This command enables metering to VMs on a host. • The command does not impact new VMs or VMs that are Live Migrated to the host.

  8. Per VM Metering

  9. The Collection Interval • Data is not collected in real time. • The default collection interval is one hour • The collection interval can only be set at the host level. • You should not collect data more frequently then once per minute.

  10. Viewing the Data

  11. Host Level Reporting

  12. Granular Reporting

  13. Granular Reporting (Continued)

  14. Sorting the Results

  15. Narrowing Down the List

  16. Another Filtering Option

  17. Building a CSV File Get-VM | Measure-VM | Export-CSV C:\Data\Performance_Data.csv

  18. Building an HTML Report • Get-VM | Measure-VM | Select-Object VMName, AvgRAM, MaxRAM, MinRAM | ConvertTo-HTML | Out-File C:\Data\Performance_Data.htm • Invoke-Expression C:\Data\Performance_Data.htm

  21. Cluster Aware Updating

  22. Cluster Aware Updating • Prior to Windows Server 2012 patching a cluster was a very tedious process. • The process was worse in extremely large clusters • Windows Server 2012 automates this process.

  23. Installing Cluster Aware Updating

  24. Installing Cluster Aware Updating

  25. Installing Cluster Aware Updating

  26. Configuring Cluster Aware Updating

  27. Configuring Cluster Aware Updating

  28. Configuring Cluster Aware Updating

  29. Setting a Schedule • Avoid running during peak business hours.

  30. Additional Options

  31. Completing the Configuration Process

  32. Searching for Updates

  33. Generate an Update Preview List

  34. The Update Preview List

  35. Applying Updates to the Cluster

  36. Updating the Cluster

  37. Completing the Update

  38. Reporting

  39. Configuring a Report

  40. Exporting Your Report

  41. The Exported HTML Report
