PRTG Network Monitor

PRTG Network Monitor by Paessler is a network performance monitoring solution focused on tracking traffic throughput, bandwidth distribution, interface availability, and device responsiveness across hybrid enterprise networks. Using native protocol sensors, PRTG Network Monitor analyzes network traffic flow using Packet Sniffing, SNMP, and flow technologies such as Cisco NetFlow, sFlow, and jFlow, allowing NetOps teams to discover exactly which applications, IP addresses, or internal departments are consuming excessive bandwidth. The solution continuously polls critical network infrastructure components, tracking interface error rates, packet loss percentages, switch temperature metrics, and power supply states to prevent unexpected network outages. PRTG Network Monitor features a distributed monitoring architecture utilizing lightweight Remote Probes that securely transmit encrypted metric telemetry from remote branch offices, subsidiary sites, and segregated DMZ networks back to the central PRTG core server without requiring expensive leased line tunnels. With real-time threshold monitoring, administrators can establish dynamic warning and error levels that trigger automated escalation actions, such as executing local recovery scripts or alerting on-call engineers. Its built-in reporting engine generates automated PDF and HTML uptime reports, validating service level agreements (SLAs) and supporting capacity planning across growing network infrastructures.
