Review Your Super Metric in Troubleshooting
After you assign your super metric to an object type, you can monitor it on the Troubleshooting tab of the
object type. Tracking a single super metric on one Troubleshooting tab is easier than tracking the metrics of
separate objects on several Troubleshooting tabs.
The super metric SM-AvgVMCPUUsage% you dened to calculate average CPU usage across all virtual machines
is assigned to the Host System object type. After one collection cycle has completed, SM-AvgVMCPUUsage%
appears as a super metric on each host.
Prerequisites
n
Create or import your super metric. See Add Your Super Metric,” on page 106.
n
Visualize your super metric to verify that it works properly. See “Visualize Your Super Metric,” on
page 106.
n
Associate your super metric to a an object type. See Associate Your Super Metric with an Object Type,”
on page 107.
Procedure
1 Select Environment > All Objects.
2 Under vCenter Adapter, expand Host System and select one of the objects.
3 On the Troubleshooting tab, select All Metrics.
4 Scroll down the metrics list to expand Super Metric and double-click SM-AvgVMCPUUsage% to view the
average CPU usage for all virtual machines that are children of the host you selected.
If the average CPU usage is low, system performance is good and your customers should not experience
long transaction processing times. You can continue monitoring the super metric for changes in average
CPU usage that might aect the customer experience. If the average CPU usage uctuates, enable the super
metric in a custom policy associated with the host objects to send an alert when the super metric value
reaches an unacceptable threshold.
Building a Super Metric Formula
A super metric formula can include one or more metric specications, super metric functions, arithmetic
operators such as the plus or minus sign, and constants. You can enter any number of constants as part of
the formula.
Procedure
u
Use the correct procedures and rules to build a super metric formula in the
vRealize Operations Manager user interface.
Option Action
To use a function.
Select it from the Function drop-down menu. Select the object or object
type, and metric or aribute type to use in its argument. The database IDs
of the object and metric appear in the formula line at the top of the
window.
To select an object and metric
Click the object in the Objects pane and double-click the metric in the
Metrics pane.
Define a metric for the object to
which the super metric is assigned.
a
Click the This Object icon or enter this on the formula line.
If the This Object icon is not selected, the super metric functions
display the object with a long description.
b In the Objects pane, click an object that contains the metric to use.
c In the Metrics pane, double-click the metric.
