Single Graph View
This view shows the collected data of one or mores sensors in one graph. If only one sensor is selected in the sensor list you can see the graph with the sensor’s data on the right.
If only one sensor is selected you can also access data tables for this sensor using the panel tabs above the graph:
These data tables show the data for the last 48 hours, last 30 days, or last 365 days:
For Packet Sniffer and NetFlow Sensors you will also see so-called Toplists (by default with lists of the Top Talkers, Top Protocols and Top Connections). For each sensor you can also configure additional customized toplists.
Toplists are based on source or destination IP and Port as well as other parameters.
In the lists you will see a number of columns for the selected values (e.g. source IP). PRTG tries to resolve the IP addresses into DNS names if possible. IP addresses shown brackets could not be resolved by reverse DNS.
The Trend column shows a value that is calculated by subtracting the current position in the list with the position of the previous toplist interval. A value of zero (0) means that an entry is at the same position in the list as in the previous interval, +5 means that the entry has climbed 5 positions. PRTG shows big changes in the list position with a background in various shades of a red to make it easy to see sudden changes.
The pie or bar chart (you can choose the type in the View|Colors & Layout dialog) always shows the data volume of the top 10 entries.
