Viewing NFS Reports
The NFS report summarizes NFS optimization statistics for the time period specified.
For details about operating report controls, see Overview.
The NFS report contains this table of statistics that summarize NFS activity:
Data Series
Description
Local Response Rate
Specifies the number of NFS calls that were responded to locally.
Remote Response Rate
Specifies the number of NFS calls that were responded to remotely (that is, calls that traversed the WAN to the NFS server).
Delayed Response Rate
Specifies the delayed calls that were responded to locally but not immediately (for example, reads that were delayed while a read ahead was occurring and were responded to from the data in the read ahead).
What This Report Tells You
The NFS report answers these questions:
•  How many NFS calls were answered locally and remotely?
•  How many delayed responses occurred for NFS activity?
About Report Graphs
Use the mouse to hover over a specific data point to see the y values and exact time stamp were in relation to peaks.
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.
Group
Select the group from the drop-down list.
