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.
