I am looking to create a custom group based on devices NOT being of a particular type. By default, it will only match if it is a particular type. In my test case, I am trying to create a group consisting of devices that are not gateways. And another that is composed of http servers that are not gateways. I noticed that the criteria is displayed as regex, so I created a group that only had gateway devices, then used the regex it produced to create an “everything except gateways” match. The negation I would normally use in regex does not seem to work. The criteria:
just returns every device, including gateways.
gets me all the http servers but, sadly, this still includes the gateways.
Does anyone have either an explanation for the regex behavior or a better way to accomplish this?
