Viewing Blockstore SSD Read Cache Reports
The Blockstore SSD Read Cache report provides performance information for the SSD disks in the block store. This report is only available on an EX1360P appliance. (You configure this feature through the CLI. For more information, see the Riverbed Command-Line Interface Reference Manual.)
What This Report Tells You
The Blockstore SSD Read Cache report answers the following question:
•  How many read hits and misses were recorded for the SSD read cache in the block store 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.
About Report Graphs
Use the mouse to hover over a specific data point to see what the y values and exact timestamp were in relation to peaks.

Description
Time Interval
Select a report time interval of 5 minutes (5m), 1 hour (1h), 1 day (1d), 1 week (1w), All, or type a custom date. All includes statistics for the last 30 days.
Time intervals that do not apply to a particular report are dimmed and unavailable.
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.
LUN
Select the LUN whose statistics you want to see from the drop-down list or select All to view all LUNs.
