Before scanning the network, input global credentials for Windows (WMI/WinRM), Linux (SSH), VMware (API), and network devices (SNMP) at the Root group level. This allows lower levels to inherit credentials automatically.
Prior to 21.x, failover nodes required manual intervention for database sync. Version 21.0.x introduced:
: It supports diverse technologies including SNMP for hardware stats, Flow (NetFlow, sFlow) for traffic analysis, and WMI for Windows-specific metrics. prtg network monitor 21.0.x
As network infrastructures evolve toward hybrid models combining on-premise, cloud, and virtual components, the need for unified monitoring solutions intensifies. This paper examines PRTG Network Monitor version 21.0.x, analyzing its architectural updates, sensor technology, probe management, and user interface improvements. The study focuses on performance metrics, scalability limits, and security enhancements relative to previous versions (20.x). Findings indicate that version 21.0.x introduces significant improvements in cluster failover handling, REST API v2, and support for modern authentication protocols, while retaining PRTG’s signature ease of use.
Remote probes collect data locally and transmit it securely to the Core Server via SSL-encrypted connections. This bypasses the need to open vulnerable inbound firewall ports across your corporate WAN. 4. Best Practices for Optimizing PRTG 21.0.x Before scanning the network, input global credentials for
If you decide to finally leave 21.0.x, follow this path:
Luis logged in remotely and ran a traceroute from an internal host. It failed at the same hop the PRTG sensor flagged. He rolled back the vendor firmware on the affected edge device, and the packet-loss graph began to fall. Within 18 minutes, green returned to most sensors. The ticket closed automatically once thresholds normalized and the incident report was queued for tomorrow’s postmortem. Version 21
Examines headers of local network packets to analyze traffic types without requiring flow-capable hardware. Cloud and Virtualization Monitoring
: The setup involves downloading the installer from the Paessler Portal and following a guided wizard.
