Types of PRO Tips

  • Article

Applies To: Operations Manager 2007, Operations Manager 2007 R2, Virtual Machine Manager

PRO-enabled management packs can define three types of PRO tips:

  • PRO tips for hosts—PRO tips for hosts can recommend actions, such as migrating a virtual machine, to return a host to a healthy state based on resource usage or other performance and health measures on the host.

  • PRO tips for virtual machines—PRO tips for virtual machines can recommend actions, such as a configuration update to return a virtual machine to a healthy state, based on resource usage or other performance and health measures in virtual machines.

  • PRO tips for VMM—PRO tips can target Virtual Machine Manager to resolve issues that affect multiple VMM-managed computers throughout your virtualized environment. For example, a PRO tip that targets VMM might define a remediation action for an overheated blade chassis, for an issue with a distributed application, such as Microsoft Exchange, that is deployed on multiple physical computers, or for an issue with a storage array.

Enabling PRO for a specific host group or host cluster in turn enables PRO for each of the hosts and virtual machines within them. PRO tips for Virtual Machine Manager are enabled through VMM PRO settings.

PRO Tips in the VMM 2008 R2 Management Pack

The following PRO capabilities are provided through the PRO-enabled management packs contained in the Virtual Machine Manager 2008 R2 Management Pack:

  • PRO tips for hosts—The PRO monitors in the VMM 2008 R2 Management Pack recommend virtual machine migration when CPU or memory usage on a host exceeds the threshold set by one of two PRO monitors. The threshold for CPU utilization on a host is calculated by subtracting the percentage of CPU resources reserved for the host operating system, which is set by host reserves in VMM, from 100 percent. The default threshold for memory utilization on a host is calculated by subtracting the memory reserved for the host operating system, which is set by host reserves in VMM, from total memory on the host. The PRO action migrates the virtual machine that has the highest resource usage on the host to the most suitable host in the same host group or host cluster by using automatic placement in VMM. These PRO tips for hosts can be implemented automatically or manually.

  • PRO tips for virtual machines—The PRO monitors in the VMM 2008 R2 Management Pack recommend configuration changes to right-size the virtual machine if it is using 90 percent or more of the CPU or memory that is allocated to it. The PRO tips for virtual machines in the VMM 2008 R2 Management Pack are not designed for automatic implementation.

The VMM 2008 R2 Management Pack does not include any VMM-level PRO monitors, so the PRO settings in Administration view will have no immediate effect. As you add new PRO-enabled management packs, be sure to check whether the management pack requires the enabling of VMM-level PRO tips.
