NPM polls static properties, such as interface speed and duplex mode, from the firewall devices using SNMP. NPM also collects traffic statistics, such as bytes in and bytes out, from the firewall interfaces using SNMP or NetFlow. NPM then calculates bandwidth consumption based on the total amount of bytes coming through the firewall over a given time interval. Bandwidth consumption is expressed as a percentage of the interface speed. For example, if a firewall interface has a speed of 100 Mbps and NPM polls 10 MB of bytes in and 10 MB of bytes out in one minute, the bandwidth consumption is 20% [(10 MB + 10 MB) / 100 Mbps * 100%]1. References: Monitor firewalls with NPM, Calculate bandwidth utilization on an interface

Response time is the amount of time it takes for a service request to return a response. It is a critical SLA performance metric for a hosted data center service, as it directly affects the user experience and satisfaction. High response time can indicate network congestion, server overload, or other performance issues that can degrade the quality of the service. By tracking response time, you can monitor the availability and reliability of the service, identify and troubleshoot potential problems, and ensure that the service meets the SLA expectations and standards. References: How to measure your SLA: 5 Metrics you should be Monitoring and Reporting, Data Center SLA Frequently Offer a 100% Uptime Guarantee, How To Measure SLA Performance in 4 Steps (With Tips).

 To monitor tenants in your SDN environment with NPM Cisco ACI monitoring, you need to add an APIC node to NPM and enable API polling on the APIC node. The APIC node is the controller of the ACI system that provides a full view of the SDN environment, including tenants, application profiles, endpoint groups, spine and leaf switches, and their health scores1. By enabling API polling on the APIC node, NPM can collect health and performance data for the ACI entities and display them on the Orion Web Console2. You do not need to enable API polling on all ACI devices, as one APIC node can provide the information for the entire ACI system3. You also do not need to view your SDN environment in Orion Maps, as this is an optional feature that allows you to visualize the relationships and dependencies among the ACI entities4. References: 1: Monitor Cisco ACI devices in NPM - SolarWinds1 2: Monitor Cisco ACI devices in NPM - Add ACI devices and enable ACI polling1 3: Monitor Cisco ACI devices in NPM - Requirements1 4: Monitor Cisco ACI devices in NPM - View ACI environment on SolarWinds Platform Maps1

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. References: 1: Network Performance Monitor Administrator Guide - Top 25 Interfaces by Percent Utilization 2: Network Performance Monitor Administrator Guide - Edit a report 3: Network Performance Monitor Getting Started Guide - Customize a report
