Viewing Data Aging Statistics for Performance

Data Aging includes Data Rollup and Garbage Collection. Data Rollup controls how often a set of data is summarized. For example, hourly data is rolled into the daily table periodically. Garbage Collection refers to how long a set of data is preserved before it is permanently removed from the database.

The settings on this page control data aging for both reports and performance statistics.

IMPORTANT: Do not modify the data on this page unless instructed by customer support. Changing them incorrectly can adversely affect the management server.

To view data aging statistics:

1.Click Optimize > Storage Essentials > Performance Data Collection.

2.Click the Data Aging tab at the top of the screen.
