There are two methods by which to filter the devices for display on either map view. After clicking the filter icon, you may choose generate your network map using either ANY applied filter or ALL applied filters collectively using the applicable radio buttons found below the data entry field.
The first method by which WhatsUp Gold applies filters to the map uses the ANY option. Using this method, as you apply additional filters, the number of devices shown is potentially increased as more match any of the filters you've applied. This method can be thought of as an "OR" filter. In other words, a device must only meet one of the criterion specified to be displayed. For example:
Example: The following filters have been applied to the My Network map with the apply ANY radio button enabled.
In this case, any device with the primary role of Windows Server OR with valid SNMPv2 credentials OR considered Up with at least one down monitor by WhatsUp Gold would be shown on the map. Only one of the three conditions must be met.
The second method by which WhatsUp Gold applies filters to the map uses the ALL option. As you apply additional filters, the number of devices shown is potentially reduced as fewer match ALL of the filters you've applied. This method can be thought of as an "AND" filter. In other words, a device must meet ALL of the criteria specified by the filters applied collectively to be displayed.
Example: The same three filters used in the previous example are applied again, however the apply ALL radio button is now enabled.
In this case, for a device to be displayed, it must have the primary role of Windows Server AND have valid SNMPv2 credentials assigned AND be currently considered Up with at least one down monitor by WhatsUp Gold. All three conditions must be met.
