> # Displaying DCNM-SAN Real-Time ISL Statistics

> This section includes the following topics:

> - "Using the Performance Manager Configuration Wizard" topic
> - "Viewing Performance Statics Using DCNM-SAN" topic

> You can configure DCNM-SAN to gather ISL statistics in real time. These ISL statistics include receive and transmit utilization, bytes per second, as well as errors and discards per ISL.

> ## DETAILED STEPS

> 1. Choose Performance > ISLs in Real-Time.

> You see any ISL statistics in the Information pane .

> 2. Select a value from the Poll Interval drop-down list.
> 3. Select two values from the Bandwidth utilization thresholds drop-down lists, one value for the minor threshold and one value for the major threshold.

> The table shown updates each polling interval to show the statistics for all configured ISLs in the fabric.

> 4. Select a row in the table to highlight that ISL in blue in the Topology map.
