Paessler PRTG Network Monitor monitors systems, devices, network traffic, applications, and other infrastructure metrics from an on-premises installation. It runs on Windows servers and includes more than 250 preconfigured sensors, each measuring one or more aspects of a device. Monitoring tools include customizable alerts, scheduled reports, distributed monitoring, and dashboards with live status information. Paessler also lists adaptive AI-driven anomaly detection and smart sensor recommendations. PRTG provides an API for monitoring data and custom features, and can send webhook notifications to Slack and Microsoft Teams. Its free iOS and Android apps display monitoring data and send push notifications, but do not support cluster setups. The free plan covers up to 100 sensors; paid plans start at $200 per month paid annually. Each server accepts one license key, so license sizes cannot be combined on a server.
