NetCrunch Licensing - Simple, Predictable, and Scalable

NetCrunch is licensed by monitored nodes and monitored interfaces — not by sensors, checks, or metrics.

This model scales cleanly from small environments to thousands of nodes and up to 100,000+ monitored interfaces, without hidden multipliers.

How it works

• Each monitored node consumes 1 node license
• Each node includes 1 interface license by default
• Additional interface licenses are only needed when you monitor many interfaces, such as on network switches
• Only interfaces that are actually monitored are counted
• Which interfaces are monitored is fully controlled by policy

For example:

• Monitoring 50 servers → 50 node licenses
• Monitoring a 48-port switch with all ports monitored → 1 node + 48 interfaces
• Monitoring the same nodes with more services, sensors, or metrics → no additional licenses

You can freely add:

• Services
• Applications
• OS metrics
• Custom checks

…without increasing license usage, as long as you are monitoring the same nodes and interfaces.

Why switches are different

Network switch ports are treated as interfaces, not separate nodes.
That’s why a fully monitored switch uses more interface licenses — but only for the ports you actually choose to monitor.

This makes licensing transparent and controllable, even in interface-dense environments.

How This Differs from Sensor-Based Licensing

Many monitoring tools use sensor-based licensing, where every individual check consumes a license.

For example:

• Monitoring 50 nodes with ping → 50 licenses
• Adding OS monitoring → +50 licenses
• Adding disk, interface, or service checks → even more licenses

This model is:

• Hard to predict
• Hard to compare
• Expensive as monitoring depth increases

NetCrunch avoids this entirely by licensing what you monitor, not how much you monitor it.

In short:
NetCrunch lets you monitor deeply, scale confidently, and plan costs accurately — from tens to thousands of nodes, and from a handful of interfaces to well over 100,000.
