Viewing data store disk load reports
The Data Store Disk Load report summarizes the data store disk load due to SDR only as related to the benchmarked capacity of the data store. Consider any value under 90 as healthy. Any value higher than a sustained load over 90 is considered high and can indicate disk pressure. A red line with shading appears at the top of the report to indicate the threshold of 90 and above. When a value is consistently higher than 90, contact Riverbed Support for guidance on reconfiguring the RiOS data store to alleviate disk pressure.

Overview.The Data Store Disk Load report contains these statistics that summarize the RiOS data store disk load.

What this report tells you
The Data Store Disk Load report answers these questions:
• Is there any indication of disk pressure?
• What is the disk load at different times of the day?

About report data
The Riverbed system reports 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.To view the Data Store Disk Load report
1. Choose Reports > Data Store: Disk Load to display the Data Store Disk Load page.
2. Use the controls to customize the report as described in this table.
Control | 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 don’t 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 doesn’t 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 isn’t visible because the system is no longer storing the data. For example, these custom time intervals don’t return data because the system automatically aggregates data older than seven days into two-hour data points: • Setting a one-hour time period that occurred two weeks ago. • Setting a 75-minute time period that occurred more than one week ago. You can quickly see the newest data and see data points as they’re added to the chart dynamically. To display the newest data, click Show newest data. |
