> # Obtaining Interface Statistics

> You can use DCNM-SAN or Device Manager to collect interface statistics on any switch. These statistics are collected at intervals that you can set.

> 2. Set both the number of seconds at which you want to poll the interface statistics and how you want the data represented in the Interval drop-down menus. For example, click 10s and LastValue/sec.
> 3. Select any tab to view those related statistics.
> 4. (Optional) Click the Pencil icon to reset the cumulative counters.
> 5. (Optional) Click the Save icon to save the gathered statistics to a file or select the Print icon to print the statistics.
