Understand the metric relationships in the memory graphs and solve the underlying resource problem for
the virtual machine.
Identify the Underlying Memory Resource Problem for Clusters and Hosts
When you navigate through a vCenter Operations Manager workflow and identify a cluster or a host with a
potential problem, check the CPU metric graphs to identify a possible resolution.
vCenter Operations Manager presents memory information that shows the metric relationships and the
breakdown of the way the virtual machines use the memory resource.
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 Click the Workload badge.
4 On the Details tab, analyze the memory metrics graphs for the virtual machine's workload.
Metric Relationship Meaning
Demand is less than Usage
Virtual machines that receive memory relinquish that memory only when
other virtual machines require it. The host does not reclaim memory from
a virtual machine just because that memory is not in demand.
Memory Reserved is less than
Memory Usable
It is acceptable for memory reservation to be less than usable memory.
However, you might want to increase the reservation to guarantee
resources in the range of normal demand.
What to do next
Understand the metric relationships in the CPU graphs and solve the underlying resource problem.
Identify the Top Resource Consumers
To address high use levels in your virtual environment, identify the top resource consumers.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 Click the Analysis tab to view the heat map gallery.
2 Depending on the resource, select a CPU, memory, network, or storage focus area.
3 To view a heat map that shows contention by use, select the host, virtual machine, or cluster object.
The larger the size of the heat map tile, the higher the use.
Click the Analysis tab to view the heat map gallery.
4 If a color other than green indicates a potential problem, click Details for the object in the pop-up
window to investigate the resources for that object.
What to do next
Identify the top consumers of resources such as CPU or memory.
