Creating Filtered Reports
NetFlow Tracker allows any chart or tabular report to be created using a powerful
dialog called the filter editor. To create a filtered report, click on “Filter Editor” on the
main page.
Most of the options in the filter editor are initially hidden to save space and bandwidth;
you can add a filter to the page by selecting it and clicking “Add”.
Each filter allows you to specify a restriction on the source data considered for the
report; if a filter is not specified it will not impose any restriction. You can choose to
include or exclude the items you select.
There are several ways to select items, depending on the type of the filter. Named
items can be selected by highlighting them in the left-hand “Available” box and using the
“>” button to move them to the right-hand “Selected” box. To deselect items highlight
them in the right-hand box and click “<”.
Some filters additionally allow you to manually enter an item in a box above the selected
box and click “Add”; to deselect an item added in this way click “<” as before. If a filter
does not have any named items there is a single selected box and a “Remove” button.
