Paessler Network Monitor, officially named PRTG Network Monitor, brings network, server, and application monitoring into one platform. A Paessler Network Monitor license sizes that platform by sensor capacity. When evaluating a PRTG Network Monitor license within the Paessler license portfolio, start with the measurements your team needs, then choose a subscription that accommodates them.
For buyers, the practical question is how much monitoring coverage each license provides. GoLicense can prepare a quote around your sensor requirements, deployment plan, and subscription needs.

Features & Benefits
Infrastructure Visibility and Bandwidth Insight
PRTG combines availability checks with performance measurements across supported infrastructure. SNMP sensors track device and interface metrics, while flow-based monitoring helps identify bandwidth usage. Administrators can investigate a busy uplink alongside server health instead of switching between disconnected monitoring tools.
Proactive Alerts and Useful Reporting
Configurable thresholds and notifications help teams respond to service failures or rising utilization. Dashboards make current conditions easier to review, and historical reports provide context for recurring incidents and capacity planning. Tune alerts around service priorities to keep routine fluctuations from overwhelming operators.
Distributed Monitoring with Central Oversight
Remote probes collect measurements close to branch systems and forward results to the central installation. This supports visibility across separated networks while retaining shared administration. Probe placement, network reachability, and polling intervals still need planning; adding locations also increases the sensor capacity required.
License Overview
A sensor monitors a particular aspect of a device or service, such as interface traffic, CPU load, or HTTP availability. One device may need several sensors. Count the checks you intend to deploy, including individual interfaces and application services, rather than treating the device inventory as the license quantity.
Current commercial subscriptions include product updates and email support. Existing perpetual installations require a separate entitlement review when discussing renewal or migration. For broader monitoring procurement, compare your requirements within the Network License portfolio.
Product Overview
PRTG Network Monitor uses a central core server for configuration, monitoring history, reports, and notifications. Probes perform the monitoring work. Depending on the sensor, collection uses technologies such as SNMP, WMI, HTTP, or flow data. Administrators manage devices, sensor settings, and access through the web interface.
Core Technical Flow
Devices and services expose measurements → local or remote probes collect data → the core server stores and evaluates results → dashboards display status → configured notifications and reports support investigation. Discovery helps create an initial inventory, but sensor selection and thresholds should reflect the services you actually need to protect.
Options & Licensing Models
The commercial sizes differ by sensor allowance. Select capacity against your monitoring design and expected growth.
| Subscription | Sensor Limit | Planning Fit |
|---|---|---|
| PRTG 500 | 500 | Focused monitoring scope |
| PRTG 1000 | 1,000 | Broader device and service coverage |
| PRTG 2500 | 2,500 | Growing infrastructure |
| PRTG 5000 | 5,000 | Extensive monitoring scope |
| PRTG 10000 | 10,000 | Large deployments requiring careful sizing |
These are monitoring capacities, not guaranteed device counts. For larger or more complex architectures, evaluate PRTG Enterprise Monitor separately.
Compatibility & Requirements
The core server requires a supported Windows system. Hardware sizing depends on sensor count, sensor types, polling frequency, and probe distribution. Confirm credentials, protocol access, firewall rules, and target compatibility before ordering. Linux multi-platform probes have their own requirements and sensor support; they do not replace the Windows core server.
Activation & Deployment
Prepare the server, install PRTG, and enter the supplied license information. Configure probes and credentials, add representative sensors, then validate measurements and notifications. Review activation procedures for restricted networks before deployment. A trial configuration can be retained when activating a commercial license.
Pricing & Quote Process
For a precise quote, provide the estimated sensor total, monitored locations, required subscription period, and whether this is a new purchase, upgrade, or existing entitlement review. Include planned growth and any activation restrictions. Request a PRTG Network Monitor quote with these details to clarify the proposed license scope before purchase.
