PRTG Traffic Grapher - User Manual

Sensors

Depending on the method of data acquisition one “sensor” can be:

·      For SNMP traffic sensors: One sensor monitors the in- and out-going traffic of one port of a device (e.g. a port of a switch or a network card of a PC)

·      For other SNMP Sensors: A sensor monitors one single parameter (e.g. the CPU usage or room temperature)

·      For Packet Sniffing: One sensor monitors all traffic going through one or more network cards. Several sensors can monitor the same network card using different filter settings (e.g. to monitor only specific IPs or protocols)

·      For NetFlow monitoring: One sensor monitors all NetFlow data packets arriving at one NetFlow Collector. Usually one Network Collector is installed per switch. Several sensors can monitor the same NetFlow Collector using different filter settings (e.g. to monitor only specific IPs or protocols)

·      For Latency monitoring: One sensor records the PING times for one remote IP address

In the main window the list of all sensors can be seen. Each sensor is shown with its current reading, device, interval and type. The colors red and yellow show error and paused sensor states.

Sensors are organized in groups and you can rearrange the order of the sensors using drag&drop.

 

What is PRTG Traffic Grapher?

PRTG Traffic Grapher is an easy to use Windows software for monitoring and classifying bandwidth usage. It provides system administrators with live readings and long-term usage trends for their network devices. The most common usage is bandwidth usage monitoring, but you can also monitor many other aspects of your network like memory and CPU utilizations.
