The Performance Explorer page enables you to compare the performance of similar objects in a cluster—for example, all the volumes in a cluster. This is beneficial when troubleshooting performance events and fine-tuning object performance. You can also compare objects with the root object, which is the baseline against which other object comparisons are made.
You can click the Favorites button () to add this object to your list of favorite storage objects. A blue button (
) indicates that this object is already a favorite.
You can click the Switch to Health View button to display the Health details page for this object. In some cases you can learn important information about the storage configuration settings for this object that may help when troubleshooting an issue.
The Performance Explorer page displays a list of cluster objects and their performance data. This page displays all the cluster objects of the same type (for example, volumes and their object-specific performance statistics) in a tabular format. This view provides an efficient overview of cluster object performance.
N/Aappears in any cell of the table, it means that a value for that counter is not available because there is no I/O on that object at this time.
The Performance Explorer page contains the following components:
You can choose a predefined range, or specify your own custom time range.
The options available depend on the root object type and its available data. You can click the View and Compare drop-down list to select an object type. The object type that you select is displayed in the list.
You can create filters that apply to the object data—for example, IOPS greater than 4. You can add up to four simultaneous filters.
Data for the objects in the Comparing pane is displayed in the Counter Charts.

Typically, only three or four charts are displayed by default. The Choose charts component enables you to display additional charts, or hide specific charts. You can also choose to show or hide the Events Timeline.
