What to do next
Continue in the workspace, adding symptoms to your alert denition. See Add a Virtual Machine CPU
Usage Symptom to the Alert Denition,” on page 51.
Add a Virtual Machine CPU Usage Symptom to the Alert Definition
To generate alerts related to CPU usage on your accounting virtual machines, you add symptoms to your
vRealize Operations Manager alert denition after you provide the basic descriptive information for the
alert. The rst symptom you add is related to CPU usage on virtual machines. You later use a policy and
group to apply alert to the accounting virtual machines.
This scenario has two symptoms, one for the accounting virtual machines and one to monitor the hosts on
which the virtual machines operate.
Prerequisites
Begin conguring the alert denition. See Add Description and Base Object to Alert Denition,” on
page 50.
Procedure
1 In the Alert Denition Workspace window, after you congure the Name and Description, Base Object
Type, and Alert Impact, click Add Symptom  and congure the symptoms.
2 Begin conguring the symptom set related to virtual machines CPU usage.
a From the  On drop-down menu, select Child.
b From the Filter by Object Type drop-down menu, select Virtual Machine.
c From the Symptom  Type drop-down menu, select Metric / Supermetric.
d Click the Add buon to open the Add Symptom Denition workspace window.
3 Congure the virtual machine CPU usage symptom in the Add Symptom Denition workspace
window.
a From the Base Object Type drop-down menu, expand vCenter Adapter and select Virtual
Machine.
The collected metrics for virtual machines appears in the list.
b In the metrics list Search text box, which searches the metric names, type usage.
c In the list, expand CPU and drag Usage (%) to the workspace on the right.
d From the threshold drop-down menu, select Dynamic Threshold.
Dynamic thresholds use vRealize Operations Manager analytics to identify the trend metric values
for objects.
e In the Symptom  Name text box, type a name similar to VM CPU Usage above trend.
f From the criticality drop-down menu, select Warning.
g From the threshold drop-down menu, select Above Threshold.
h Leave the Wait Cycle and Cancel Cycle at the default values of 3.
This Wait Cycle seing requires the symptom condition to be true for 3 collection cycles before the
symptom is triggered. This wait avoids triggering the symptom when there is a short spike in CPU
usage.
