User’s Guide – version 3.5 NetFlow Tracker

Some filters allow a range of items to be added; in this case enter the start and end of the range in the boxes provided. To select a single item, leave the right-hand box empty,

If you are logged in as an administrator or not logged in you can save a filter by clicking “Save…” at the bottom of the page. This allows you to assign a name to a set of filters for re-use later. If you have any saved filters defined they are available in the same dropdown list used to add filters to the page. Saved Filters are managed in Report Settings.

Report template

You can choose the type of element you wish to report here, and specify whether you want to create a tabular report, chart or pie chart. For more about the different types of report, see Report Templates above.

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.
