Prtg Network Monitor — 21.0.x __exclusive__
Organize devices by physical site if you use Remote Probes, or by operational team (e.g., Database Group, Security Group).
Unlike modular monitoring tools that require separate purchases for different protocols, PRTG includes all features in every license. It operates on a sensor-based licensing model, where a "sensor" represents a single aspect of a device—such as a specific switch port, CPU load, or disk space. 2.

Network monitoring systems are high-value targets for malicious actors because they contain administrative credentials for your entire infrastructure. Implement these security protocols to protect your PRTG deployment: Organize devices by physical site if you use
Network uptime is the backbone of modern business operations. Paessler PRTG Network Monitor has long been a trusted solution for IT administrators seeking comprehensive visibility into their infrastructure. The release of PRTG 21.0.x brought significant refinements, balancing core monitoring stability with modernized security and user interface updates. Paessler PRTG Network Monitor has long been a
In previous versions, cluster nodes sometimes suffered from synchronization lags, leading to false "down" alerts during failover testing. Version 21.0.x hardened the database replication protocol, ensuring that configuration changes (like adding a sensor or modifying a threshold) replicated within seconds across all nodes in a cluster.
The built-in web interface received significant responsiveness updates in 21.0.x. Page load times for massive device trees are shorter, and search indexing across thousands of sensors is more efficient. Cloud and Virtualization Monitoring
The "21" in the version signifies the release year (2021), introducing a rapid-rollout model where minor versions (the ".0.x" stream) delivered continuous stability improvements, updated sensory capabilities, and hardened security protocols. The PRTG Licensing Model: Sensors Explained
