Viewing Active Sessions in Micro Edge

Click Sessions in the navigation bar at the top of the screen to access this view.

Filtering Sessions

There are two ways to filter the data shown in the Sessions viewer: globally or per-column.

Global Filtering

You can use the Search here… field at the top left-hand corner to apply a single filter to the entire Sessions view. Anything you type into this field will be checked against all attributes of each session. Only the ones which have an attribute matching your entry will be shown.

This option is great when looking for sessions matching a single criterion: all traffic from one host IP, all traffic generated by a particular application, all traffic using a specified WAN, and so on.

Per-Column Filtering

You can also add a filter to each individual column, which gives you the ability to create more complex filtering conditions. Hover your mouse over the header for the column you would like to filter and click the three horizontal lines to open the "additional options" menu, then type your desired filter condition into the Filter field.

A per-column filter modifies only that specific column. You can combine several per-column filtering conditions to create a more complex filter, such as "display all traffic from 192.168.2.25, using the Facebook application, passing through WAN 0".

When a filter condition is in effect for a given column, the header will display an icon:
