PRTG monitors all systems, devices, traffic and applications of your IT infrastructure using these technologies:

• SNMP: ready to use and custom options
• WMI and Windows Performance Counters
• SSH: for Linux/Unix and MacOS systems
• Flows and Packet Sniffing
• HTTP requests
• Any REST API returning XML or JSON
• Ping, SQL and many more

With PRTG Traffic Grapher you will receive bandwidth and network usage data that helps optimize the efficiency of your network. Understanding bandwidth and resource consumption is the key to better network management:

• Avoid bandwidth and server performance bottlenecks
• Find out what applications or servers use up your bandwidth
• Plan upgrades of your infrastructure strategically
• Deliver better quality of service to your users by being proactive
• Reduce costs by buying bandwidth and hardware according to actual load traffic by using a switch with a »monitoring« port.
• Netflow: The NetFlow protocol is supported by most Cisco routers to measure bandwidth usage. Although being the most complex type to set up it is also the most powerful method suitable for high traffic networks.

• PRTG Traffic Grapher runs on a Windows machine in your network for 24 hours every day and constantly records the network usage parameters. The recorded data is stored in an internal database for later reference.
  
  
• Using an easy-to-use Windows interface you can configure the monitored sensors as well as create usage reports. For remote access PRTG Traffic Grapher comes with a built-in web server to provide access to graphs and tables.

All Common Methods for Network Usage Data Acquisition are Supported

• SNMP: Simple Network Management Protocol is the basic method of gathering bandwidth and network usage data. It can be used to monitor bandwidth usage of routers and switches port-by-port as well as device readings like memory, CPU load, etc.
  
  
• Packet Sniffing: With its Packet Sniffer PRTG can inspect all network data packets passing a network card. You can monitor either only the traffic of the machine running PRTG or all network
