Identify Top Talkers, Top Connections & Top Protocols with PRTG
Activity And Usage Monitoring
You can configure Top Lists to find out what applications or what servers are using up your bandwidth.
- Top Talkers
- Top Connections
- Top Protocols
This covers the most basic needs for usage monitoring, but you can also edit the three toplists or create additional ones. Further information on editing Toplists can be found here.
When working with Toplists for usage monitoring be aware that privacy issues can come up for certain configurations of this feature since you monitor IP addresses of users. Using Toplists you can track all single connections of an individual PC to the outside world and you, as the administrator, must make sure that it is legal for you to configure PRTG like this.
Usage monitoring is important to identify causes for bandwidth bottlenecks, that are not caused by faulty systems, but an excessive bandwidth usage by single servers or users.
Usage monitoring software such as PRTG Network Monitor analyzes the traffic in your network and provides you with detailed information on usage and activity. The results of the usage monitoring can be total bandwidth (e.g. flowing through a port of a switch) or drilled down to protocols.
How to Configure Top Lists For Usage Monitoring
In order to discern excessive usage based on IP addresses you can set up usage monitoring based on Top Lists as follows:
- Configure the device(s) to send a copy of all network packets to the IP of the machine running PRTG
- Create one new Packet Sniffer / Netflow Collector sensor for each PC to be monitored and apply a filter based on the MAC address or IP of each PC you want to monitor
- Or: If you do not need long term accounting data for each PC and only want to know the current and recent traffic by IP, you can create just one Packet Sniffer sensor and enable the Toplist feature based on IP.
Once the relevant sensors are defined, you can recognize bandwidth usage either by comparing the individual sensor data or by monitoring the top list entries. Top lists also include a trend entry allowing to determine, at a glance, what machines / users are using more / less bandwidth than in prior scans. Furthermore, top lists will include listings of visited IP addresses (optionally, DNS (Domain Name System, DNS servers resolve server names into the actual IP address of the server) resolution can be turned on in the top list settings), allowing to determine what machine / user accessed what server / web site.
Note: If you have several switches / routers you may not see all traffic if you only monitor one device.
Note: In order to monitor network traffic by IP address or protocol used by a shared Internet connection or leased line, please select filtering to exclude LAN IP addresses.
