NPM provides several default reports that can be used as templates for creating custom reports. One of them is the Top 100 Interfaces by Percent Utilization report, which shows the average and peak utilization of the most used interfaces in the network. To create a report that shows only the top 50 interfaces, you can copy this report and edit it to change the number of rows displayed. You can also modify other parameters such as the time period, the grouping, the sorting, and the filtering criteria. To copy and edit a default report, follow these steps1:
Click Reports > All Reports > Manage Reports.
Find the Top 100 Interfaces by Percent Utilization report and click Duplicate & Edit.
On the Layout Builder panel, click Edit Table.
On the Edit Resource panel, change the Maximum Number of Rows to 50.
Optionally, change other settings such as the Time Period, the Group By, the Sort By, and the Filter Results.
Click Submit.
Optionally, change the Report Name, the Report Description, and the Report Category.
Click Next and then Save.
You can now run or schedule the report to show the top 50 interfaces by percent utilization. References: 1: Create a custom report for NPM showing availability of devices in the last 30 days
