Aributes An aribute is a collectible data component. You can enable or disable metric, property, and
super metric aributes for collection, and set aributes as key performance indicators (KPIs).
A KPI is the designation of an aribute that indicates that the aribute is important in your
own environment.
vRealize Operations Manager treats KPIs dierently from other aributes. Threshold
violations by a KPI generate dierent types of alerts from non-KPI aributes.
When a KPI violates a threshold, vRealize Operations Manager examines the events that
preceded the violation. If it nds enough related information, vRealize Operations Manager
captures the set of events that preceded the violation as a ngerprint. If it nds a similar
series of events in the future, it can issue a predictive alert warning that the KPI violation is
likely to occur.
Alert Denitions Enable or disable combinations of symptoms and recommendations to identify a condition
that classies as a problem.
Symptom Denitions Enable or disable test conditions on properties, metrics, or events.
Privileges To Create, Modify, and Prioritize Policies
You must have privileges to access specic features in the vRealize Operations Manager user interface. The
roles associated with your user account determine the features you can access and the actions you can
perform.
To set the policy priority, on the Active Policies tab, click the policy row and drag it to place it at the desired
priority in the list. The priority for the Default Policy is always designated with the leer D.
How Upgrades Affect Your Policies
If you upgrade vRealize Operations Manager from a previous version, you must analyze your existing
policies and modify the seings to optimize them for your current environment. If you apply the policies
used with a previous version of vRealize Operations Manager, the policy seings remain unaltered.
Policy Decisions and Objectives
Implementing policy decisions in vRealize Operations Manager is typically the responsibility of the
Infrastructure Administrator or the Virtual Infrastructure Administrator, but users who have privileges can
also create and modify policies.
You must be aware of the policies established to analyze and monitor the resources in your IT infrastructure.
n
As a Virtual Infrastructure Administrator who manages and troubleshoots an IT infrastructure, you
must understand how policies associated with objects aect the scores that appear in
vRealize Operations Manager, so that you can congure the approved policies based on your company
decisions and requirements.
