7 Use the options to evaluate the datastore.
For example, what does the map tell you about the number of virtual machines that are associated with
the datastore? If many virtual machines are associated with a datastore, moving them might free
datastore disk space.
What to do next
n
If your review of the map provided enough information to indicate that one or more of the
recommendations to resolve the alert are valid, implement the recommendations. See “Run a
Recommendation On a Datastore to Resolve an Alert,” on page 18.

If you need more information about the aected object, continue your investigation. See “Construct
Metric Charts to Investigate the Cause of the Data Store Alert,” on page 17.
Construct Metric Charts to Investigate the Cause of the Data Store Alert
To analyze the capacity metrics related to the generated alert, you create charts in
vRealize Operations Manager that compare dierent metrics. These comparisons help identify when
something changed in your environment and what eect it had on the datastore.
As a network operations engineer, you create custom charts so that you can further investigate the problem,
and to determine if implementing the alert recommendations will resolve the problem that the alert
identies.
Prerequisites
View the topological map for the data store to determine if related objects are contributing to the alert or if
triggering symptoms indicate that the data store is contributing to other problems in your environment. See
“View the Aected Datastore in Relation to Other Objects,” on page 16.
Procedure
1 In the left pane of vRealize Operations Manager, click the Alerts icon.
2 Click the alert name link.
The center pane view changes to display the alert detail tabs.
3 Click the Metric Charts tab.
The Metric Charts tab does not include charts. You must add the charts to compare.
4 To analyze the rst recommendation, Add more capacity to the Datastore Storage, add related charts to
the workspace.
a Enter capacity in the metric list search text box.
The list displays metrics that contain the search term.
b Double-click the following metrics to add the following charts to the workspace:
n
Capacity | Used Space (GB)
n
Disk Space | Capacity (GB)
n
Summary | Number of Capacity Consumers
c Compare the charts.
For example, if the Capacity | Used Space (%) chart shows an increase in used space, but the Disk
Space | Capacity (GB) did not increase and the Summary | Number of Capacity Consumers did
not decrease, then adding capacity is a solution, but it does not address the root cause.
