First of all, for those who are not very familiar with NetFlow, it is a functionality which allows you to capture IP network traffic of your nBoxes. The traffic is collected as it comes in your network interface. Using tools like Nfdump the network flows can be exported and analyzed.
So, what we introduced in our new and innovative reporting tool was to offer you the possibility to display NetFlow statistics within the specified time frames directly on your reports. You can find these two new sections entering the edit mode of a report and adding one of them.
The Top Flow Statistics section shows you the biggest flows in a specific time frame in descending order according to the Bytes column. Additionally to the size of the flow it shows also the IP network protocol, the source and destination IP addresses and the source and destination ports. This feature lets you analyze and identify the biggest flows in that time frame, which influences most the network traffic.
Using the Top In/Out Flows section the report lets you analyze the network flows aggregated by their network protocols and ordered by their byte percentage. The section shows the aggregated flows in two line charts, one for the incoming flows and one for the outgoing ones.
Additionally it shows also the details of the aggregated flows inside two tables next to the charts ordered by their percentage of bytes, again separated in input and output flows.
Remember that if you are not happy with the predefined time periods like last 24 hour or last 7 days or also a specific month you can always use the custom time period selector which lets you choose the start and end date and time according to your specific needs.
Or you have also the possibility to specify the time periods directly inside the settings of the two new sections, which can be in almost any common format.
