NPM provides a default report called Top 25 Interfaces by Percent Utilization that shows the interfaces with the highest average utilization over the selected time period1. This report can be easily edited to change the number of interfaces displayed, the time period, the sorting order, the layout, and the filters2. To create a report that shows the top 50 interfaces by percent utilization, you can simply edit this report and change the Limit option from 25 to 503. This is the most time-efficient way to create the report, as it does not require creating a new report from scratch, writing a SQL query, or running the report multiple times for different timeframes.
