Identify the Underlying Memory Resource Problem for a Virtual Machine
When you navigate through a vCenter Operations Managerworkflow and identify a virtual machine with a
potential problem, you can resolve the underlying problem by using the memory metric data.
The CPU graphs for clusters and hosts show the Provisioned metric. The CPU graphs for virtual machines
show the Entitlement metric. See “Metric Concepts for vCenter Operations Manager Planning,” on page 8.
Prerequisites
In the vCenter Operations Manager interface, verify that the Dashboard tab is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the Environment tab under the Operations tab.
3 If the color of the badge is other than green, double-click it.
4 On the Details tab, select the Workload badge to analyze the memory metrics graphs.
Metric Relationship Meaning
Demand is equal to Usage
Object has enough resources.
Demand is greater than Usage
Virtual machine might be in the process of waiting for CPU cycles.
Demand is greater than Usage and
less than Provisioned
This metric relationship indicates the following implications:
n
Limits set on a virtual machine might cause the virtual machine to use
less CPU resources than the demand. vCenter Operations Manager
aggregates CPU metrics for virtual machines into the host CPU graph.
n
The CPU Dynamic Power Management in the BIOS might cause a CPU
issue. Verify that the setting is in operating system control mode or
disable the setting.
n
Virtual machines that are usually idle but happen to become busy at the
same time might cause contention.
Understand the metric relationships in the memory graphs and solve the underlying resource problem for the
virtual machine.
Determine the Percentage of Used and Remaining Capacity to Assess
Current Needs
The Capacity Remaining pane under the Risk badge provides an overview of the used and remaining capacity
for all objects except virtual machines.
You can use the bar chart under the Capacity Remaining badge to determine how much space you have in
which to add new virtual machines to your environment.
Prerequisites
In the vCenter Operations Manager interface, verify that the Dashboard tab is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the arrow under the Risk badge to expand the detailed view.
3 Under the Capacity Remaining badge, review the bar chart of used and remaining capacity.
4 To view more details about capacity-related metrics, click the Capacity Remaining badge.
