What This Report Tells You
The Blockstore Metrics report answers these questions:
•  How many read hits and misses, in megabytes, were recorded for the blockstore for the selected LUN for the specified period?
•  How many uncommitted bytes were recorded for the blockstore for the selected LUN for the specified period?

About Report Data
The Riverbed system reports on performance for periods up to one month. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled.
For detailed information about data grouping, see Data Grouping.

Description
Time Interval
Select a report time interval of 1 hour (1h), 1 day (1d), 1 week (1w), 30 days (30d), yesterday, last week, or last month.
Time intervals that do not apply to a particular report are dimmed.
For a custom time interval, enter the start time and end time using the format YYYY/MM/DD HH:MM:SS.
Because the system aggregates data on the hour, request hourly time intervals. For example, setting a time interval to 08:30:00 to 09:30:00 from 2 days ago does not create a data display, whereas setting a time interval to 08:00:00 to 09:00:00 from 2 days ago will display data.
When you request a custom time interval to view data beyond the aggregated granularity, the data is not visible because the system is no longer storing the data. For example, the following custom time intervals do not return data because the system automatically aggregates data older than 7 days into 2-hour data points:
•  Setting a 1-hour time period that occurred 2 weeks ago.
•  Setting a 75-minute time period that occurred more than 1 week ago.
You can quickly see the newest data and see data points as they are added to the chart dynamically. To display the newest data, click Show newest data.
