g 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 three collection cycles before
the symptom is triggered. This wait avoids triggering the symptom when a short spike occurs in
host memory usage.
h Click Save.
The dynamic symptom identies when the hosts on which the accounting virtual machines run are
operating above the tracked trend for memory usage.
The dynamic symptom is added to the symptom list.
4 In the Alert Denition Workspace window, drag Host memory usage above trend from the symptoms
list to the symptom workspace on the right.
The Self-Host System symptom set is added to the symptom workspace.
5 On the Self-Host System symptom set, from the value type drop-down menu for This Symptom set is
true when, select Any.
With this conguration, when any of the hosts running accounting virtual machines exhibit memory
usage that is above the analyzed trend, the symptom condition is true.
6 At the top of the symptom set list, from the Match {operator} of the following symptoms drop-down
menu, select Any.
With this conguration, if either of the two symptom sets, virtual machine CPU usage or the host
memory, are triggered, an alert is generated for the host.
You dened the second symptom set for the alert denition and congured how the two symptom sets are
evaluated to determine when the alert is generated.
What to do next
Add recommendations to your alert denition so that you and your engineers know how to resolve the alert
when it is generated. See Add Recommendations to the Alert Denition,” on page 53.
Add Recommendations to the Alert Definition
To resolve a generated alert for the accounting department's virtual machines, you provide
recommendations so that you or other engineers have the information you need to resolve the alert before
your users encounter performance problems.
As part of the alert denition, you add recommendations that include actions that you run from
vRealize Operations Manager and instructions for making changes in vCenter Server that resolve the
generated alert.
Prerequisites
Add symptoms to your alert denition. See Add a Host Memory Usage Symptom to the Alert Denition,”
on page 52.
