Flow Collectors
if there is at least one Flow Sensor in use. The number of
active Flow Collectors is displayed within the panel.
Here you can list, aggregate, filter and sort flow records, and generate traffic tops and statistics.
There are 2 sub-tabs, located at the left lower side of the window:
Flow Records
You can list and filter flow data. The options are:
●
Flow Sensors
– Select the interfaces you are interested in. Administrators can restrict the interfaces
accessible by guest accounts.
●
Time Frame
– Select a predefined time frame, or select “Custom...” to enter a specific time interval, in
order to list flows that started or ended inside the interval. Time zone differences between the Console
server and remote Flow Sensor servers are not automatically adjusted.
●
Flow Filtering Expression
– Here you can enter a filtering expression for flows. Click the light bulb icon
on the right to open a window that shows you the correct syntax. Frequently-used flow filters can be
saved there and reused at a later time.
●
Output
– You can select several output formats, or you can type your own format. Click the light bulb
icon on the left to open a window that shows you the correct syntax.
●
Export
– If the output is not very large, it can be viewed, emailed or printed.
If you need to list huge amounts of flow data, doing it solely from within the web browser may not be a
good idea. In this case, select the “Dump” option to view the CLI command used for flow listing. You can
execute that CLI command from the shell and forward the output to a file.
●
Aggregation
– By default, flows are not aggregated. By clicking on the appropriate checkboxes, you can
select how to aggregate flows. You can aggregate entire subnets by selecting src(dst)IPv4(IPv6)/<subnet
bits>.
●
Limit Flows
– List only the first N flows of the selected time slot.
●
Sorting –
When listing flows sent by different interfaces, you can sort them according to the start time of
the flows. Otherwise, flows are listed in the sequence of the selected interfaces.
Flow Tops
You can generate tops from flow data. The options are:
●
Flow Sensors
– Select the interfaces you are interested in. Administrators can restrict the interfaces
accessible by guest accounts.
●
Time Frame
– Select a predefined time frame, or select “Custom...” to enter a specific time interval, in
order to count only flows that started or ended inside the interval. Time zone differences between the
