Summary

Paessler PRTG Network Monitor monitors systems, devices, traffic, applications, and other infrastructure metrics from an on-premises installation running on Windows servers. It includes more than 250 preconfigured sensors, each measuring one or more aspects of a device. Customizable alerts, scheduled reports, distributed monitoring, and live-status dashboards help teams follow infrastructure. Paessler also lists adaptive AI-driven anomaly detection and smart sensor recommendations. Notifications can use email, SMS, webhooks, or mobile; webhooks can connect with Slack and Microsoft Teams. An API provides access to monitoring data and supports custom features. Free iOS and Android apps display monitoring data and send push notifications, but do not support PRTG cluster setups. Paessler describes the product as suited to small and medium IT infrastructures, with features for OT and IoT environments. The free edition allows up to 100 sensors, while paid plans start at $200/mo when paid annually. Each server accepts one license key, so different license sizes cannot be combined on a server.
