Microsoft.SystemCenter.VirtualMachineManager.ManagedHost.MemoryAvailableMBytes.Collection (Rule)

Knowledge Base article:

Summary

This rule collects total available memory (in MB) on managed virtual machine hosts in System Center Virtual Machine Manager (VMM). The data is used by the Host Utilization and Host Utilization Growth reports. By default, data is collected every 15 minutes.

About the reports:

Host Utilization - For the specified time period and host group, the Host Utilization report shows the number of virtual machines running on each host and the average usage and total or maximum values for host processors, memory, and disk space.
Host Utilization Growth - This report shows the percentage of change in resource usage and the number of virtual machines running on selected hosts during a specified time period.
