NetFlow Tracker

Sample Size

NetFlow Tracker picks an optimal sample size for a real-time chart based upon the amount of time covered; you can override this by selecting a number of units. For example, you can create a report covering a day with each sample being an hour long.

Source Data

Long-term data is stored in samples of various sizes that are optimal for different lengths of chart; you can override the automatic selection of the source data to create charts showing, for example, a month in day-long blocks.

Start Time

Pick the date and time of the earliest data to consider. The default value is six hours before you opened the filter editor.

End Time

Pick the date and time of the last data to consider.

Length

Instead of specifying a start and end time you can specify a length in units; the report will cover that number of units and end at the last full unit before the time it is opened.

Reload Interval

If you have selected a unit length or a time range that extends into the future you may want the report to refresh automatically to show new data; if so, enter the number of seconds between automatic refreshes here.

Time Mask

You can use the time mask filter to select only certain times of day within the time range. For example, you can choose to only consider data between 8:30 and 18:00 on a weekday. To do this, select Monday, Friday, 8:30 and 18:00 and press “Add”:

You can add as many masks as you wish; only data within one or more masked areas is considered. If no masks are selected then all data between the start time and end time is considered.

Time Zone

You can change the time zone used to interpret the start and end times and time masks from the default of the time zone used by the NetFlow Tracker server.

Source Device

You must select which router or switch you want to consider. If you need to consider more than one device, click “Multiple…”, but be aware that if you select multiple devices there is a chance that some or all traffic may be accounted for multiple times.

In Interface

You can report on inbound traffic for an interface or set of interfaces by adding them to the in interface filter. The interfaces you can pick depend on the filtered source devices.
