Configure the Custom Policy Settings to Analyze and Report on vSphere Objects
You use dierent policy requirements for your Development, Test, and Production environments so that you
can congure the specic policy seings for vRealize Operations Manager to analyze and report on your
objects, including your virtual SQL Servers.
This scenario presents several typical cases where you might be required to dierentiate between the policy
requirements for Development, Test, and Production environments.
n
For your Development and Test environments, you might not be concerned if the objects in these
environments experience network redundancy loss, but you do care when the objects fail. In this case,
you locate the Physical NIC link state alert denition, double-click the state, and set it to Disabled.
n
For a Test environment, you might not be concerned if your virtual machines demand more memory
and CPU capacity than what is actually congured, because workloads can vary in test environments.
n
For a Production environment, your virtual machines might require more memory than you have
congured, which might cause a problem with the performance and reliability of your production
environment.
In this procedure, you override the symptom denition threshold value for the Co-Stop performance of your
virtual machines.
Prerequisites
Verify that the following conditions are met:
n
You created a custom policy for your virtual SQL Servers. See “Create a Policy to Meet vSphere
Operational Needs,” on page 88.
n
You understand the Co-Stop CPU performance metric for virtual machines. This metric represents the
percentage of time that a virtual machine is ready to run, but experiences delay because of co-virtual
CPU scheduling contention. Co-Stop is one of several performance metrics for virtual machines that
also include Run, Wait, and Ready.
n
The alert denition named Virtual machine has high CPU contention caused by Co-Stop, exists.
n
Symptom denitions exist to track the critical, immediate, and warning levels of CPU Co-Stop on the
virtual machines. For example, the critical level for virtual machine CPUs that experience contention
more than 15% of the time is set to 15% by default, as measured by the Co-Stop metric. The default
threshold level for Immediate is 10%, and for warning is 5%. However, in your production policy for
your production virtual machines, you manage the critical level at 3%.
Procedure
1 On the Policy Library tab, locate your vSphere Production Virtual SQL Servers policy, and click the
pencil to edit the policy.
The Edit Monitoring Policy workspace appears.
2 In the workspace, click Override Alert / Symptom .
3 On the Alert Denitions pane, enable the Co-Stop alert denition to notify you about high CPU
contention on your virtual machines.
a In the Object Type drop-down menu, select vCenter Adapter and Virtual Machine.
b In the Search text box, enter stop to display only the alert denitions that relate to the Co-Stop
performance metric for virtual machines.
c For the Alert denition named Virtual machine has high CPU contention caused by Co-Stop,
click the State drop-down menu and click Enabled.
