Publisher review
SolarWinds Network Performance Monitor (NPM) is an enterprise-grade network monitoring platform designed for IT teams managing mid-to-large-scale multi-vendor environments. Launched in 1999 and headquartered in Houston, Texas, NPM captures approximately 20% of the enterprise network monitoring market. It is best suited for organizations that require deep visibility into on-premises network infrastructure, with out-of-the-box support for thousands of device models via SNMP, WMI, NetFlow, sFlow, jFlow, and Syslog. The tool targets network engineers who need real-time diagnostics and customizable dashboards but can tolerate a steeper initial learning curve and higher licensing costs compared to open-source alternatives.
NPM operates primarily through an agentless architecture, using SNMP as its core protocol to poll device health, bandwidth utilization, and interface status. Key capabilities include Network Insights for automated dependency mapping, Intelligent Maps for visual topology, and NetPath for hop-by-hop path analysis across hybrid networks. PerfStack enables drag-and-drop correlation of performance metrics across multiple time series. The platform supports distributed monitoring via polling engines and scalability engines, allowing it to handle environments with thousands of nodes. Advanced alerting triggers can be customized with multi-condition rules and sent via email, SMS, or Slack. Licensing is node-based, starting at $2,995 for the SL100 tier (100 monitored elements) and scaling through SL250, SL500, SL2000, and SLX tiers as infrastructure grows.
In the network monitoring market, SolarWinds NPM competes directly with Zabbix, PRTG Network Monitor, ManageEngine OpManager, Datadog, and Cisco Network Management. Compared to Zabbix, which is free and open-source but requires Linux servers and significant manual configuration, NPM offers a more polished Windows-based interface with prebuilt dashboards and templates. PRTG uses a sensor-based licensing model that can become expensive at scale, while NPM’s node-based licensing provides clearer cost predictability for large environments. Datadog excels in cloud-native monitoring but lacks the deep on-premises SNMP coverage that NPM provides. ManageEngine OpManager offers similar features at a lower price point but with less advanced path analysis and alerting capabilities.
The honest trade-offs: NPM’s extensive feature set can overwhelm new users, and initial setup often requires dedicated training or professional services. The user interface occasionally lags when rendering large network maps with hundreds of devices. Licensing complexity — with multiple tiers and add-on modules — can lead to unexpected cost increases as environments scale. Cloud monitoring support remains limited compared to native cloud tools like Datadog, and the platform’s Windows-only deployment may be a constraint for Linux-centric shops. Despite these drawbacks, NPM remains a strong choice for organizations that prioritize deep on-premises network visibility and are willing to invest in licensing and training.
How it works
-
Multi-vendor network monitoring
Supports SNMP, WMI, NetFlow, sFlow, jFlow, and Syslog to monitor devices from Cisco, Juniper, HP, Dell, and hundreds of other vendors out of the box.
-
Network Insights
Automatically discovers and maps network dependencies, reducing manual configuration time by identifying device relationships and traffic flows.
-
Intelligent Maps
Generates dynamic, color-coded topology maps that update in real time to reflect network changes and alert on degraded links.
-
NetPath and PerfStack
NetPath traces hop-by-hop network paths; PerfStack allows drag-and-drop correlation of metrics like CPU, bandwidth, and latency across time series.
-
Smarter scalability
Uses distributed polling engines and scalability engines to monitor thousands of nodes without degrading performance, supporting large enterprise environments.
-
Advanced alerting
Supports multi-condition triggers, escalation policies, and notification delivery via email, SMS, Slack, and webhooks for proactive incident response.
-
Customizable dashboards and reports
Provides drag-and-drop widgets for real-time dashboards and prebuilt reports for compliance, capacity planning, and SLA tracking.
Strengths and trade-offs
Strengths
- Real-time alerts and diagnostics reduce mean time to resolution by providing immediate notification of interface flaps, bandwidth spikes, and device outages.
- Intuitive dashboard with drag-and-drop widgets allows network engineers to visualize up to 50+ metrics simultaneously without writing queries.
- Broad device support covers over 1,000 vendor-specific MIBs out of the box, minimizing manual template creation for heterogeneous networks.
- NetPath and PerfStack enable hop-by-hop path analysis and cross-metric correlation, cutting troubleshooting time from hours to minutes.
Trade-offs
- Initial setup can take 2-4 weeks for a mid-sized network due to complex licensing configuration and the need to tune polling intervals for each device type.
- Occasional lags in the user interface when rendering maps with more than 500 nodes, especially during peak polling periods.
- Higher costs compared to open-source alternatives like Zabbix, with annual licensing for 100 nodes starting at $2,995 and scaling to over $15,000 for 2,000 nodes.
- Limited cloud monitoring support — native capabilities for AWS, Azure, and GCP require separate SolarWinds modules or third-party integrations.
Pricing context
Starting from $2,995 per node for the SL100 license (100 monitored elements), with higher tiers SL250, SL500, SL2000, and SLX available. A 30-day free trial and 30-day no-obligation demo are offered.
Getting started with Network Performance Monitor
-
Download and install NPM
Visit the SolarWinds website and download the Network Performance Monitor installer. Run the executable on a Windows server, accept the license agreement, and follow the setup wizard to complete the installation.
-
Configure SNMP credentials
Open the NPM web console and navigate to Settings > Network Discovery. Add SNMP community strings or credentials for your devices, specifying read-only strings for polling and write strings if needed for configuration.
-
Run network discovery
In the Discovery Center, define an IP range or subnet to scan. Click Start Discovery to let NPM automatically find devices, interfaces, and dependencies. Review the discovered nodes and import them into monitoring.
-
Create a custom dashboard
From the Home menu, select Dashboards and click Create New Dashboard. Drag and drop widgets such as Top N Interfaces, Bandwidth Utilization, and Device Health. Arrange them to visualize your key metrics in real time.
-
Set up alerting rules
Go to Alerts > Manage Alerts and click Add New Alert. Define conditions like CPU over 90% or interface down, set escalation policies, and choose notification channels such as email or Slack. Save and enable the alert.
