Device Groups - Multiple Parameter Rules Stopped Working

Help
1

Hi All

I have been using Device Groups for a while now and it’s made life a lot simpler for certain operations. Recently however, I had to add an additional parameter (devices.hostname, ends with, “ret” for instance) in a group with about 10 or so “rules” and it stopped working completely (returns with 0 devices). I removed the new parameter but that did not solve the issue. On creating a test group, it works fine if there is only one parameter, but as soon as I enter a 2nd it returns 0 devices. I have another device group which has also been there for some time, with 4 parameters set and it still continues to function as normal.

Any idea what could be causing this or how I can fault find this issue?

Ok, so I had a senior moment it seems and switched the rule from “Or” to “And” and unfortunately my logic then led me even further astray … this parameter AND this parameter etc. instead of look for this parameter OR this parameter, which then looks for everything separately instead of one big hostname with EVERYTHING that I specified in it :see_no_evil:

My bad, won’t do that again.
