WhatsUp Gold is preconfigured with dynamic group examples, which you can see in the Devices view, under Device Groups. For more information on these groups, see Configuring Dynamic Groups.
The following examples show several dynamic group filters that you can use to create some interesting dynamic groups for your devices. To use these examples, select the text of the filter, and then copy and paste the text into the Filter box of the Dynamic Group dialog.
Note: You may have to remove the copyright information from the cut and paste if it appears when you copy from this help file.
