New features and improvements in NPM

Last updated:

Network Performance Monitor 2025.1 includes the new features in version 2025.1 of the SolarWinds Platform. For more information, see the SolarWinds Platform 2025.1 Release Notes.

Enhanced SNMP polling for Aruba devices

Monitor the following metrics for your Aruba switches:

  • Hardware health
  • Layer 2 metrics, such as MAC address table utilization, CDP/LLDP topology, Spanning Tree Protocol (STP) status, VLAN configuration and usage
  • Layer 3 metrics, such as routing table utilization and ARP table utilization.

Enhanced SNMP polling for Fortinet devices

Monitor the following metrics for your Fortinet switches:

  • Hardware health
  • Layer 2 metrics, such as MAC address table utilization, CDP/LLDP topology, and VLAN configuration and usage
  • Layer 3 metrics, such as ARP table utilization.

Support for monitoring Ruckus SmartZone and Extreme Networks wireless access points

Using API, you can monitor the following aspects for your Ruckus SmartZone and Extreme Networks wireless networks:

  • Wireless network strength: total number of access points, the total number of users, or rogue access point signal strength
  • Wireless network utilization: CPU and memory utilization, availability and response time
  • Wireless network traffic: total bytes sent and received by access points and total bytes sent and received by clients

See Monitor Ruckus SmartZone wireless infrastructure and Monitor Extreme Networks Cloud IQ wireless infrastructure.

API-only polling for SD-WAN vendors

See API polling for details about vendor-specific polling and polling limits.

API-only polling for VeloCloud SD-WAN edges

In earlier releases, VeloCloud SD-WAN edge devices were polled via a combination of SNMP and API. In 2025.1, you can poll VeloCloud edge devices as API-only nodes. See SNMP or API-based monitoring for VeloCloud devices.

Improved API-only polling for Prisma SD-WAN

API-only polling now supports polling Interfaces and CPU & memory.
