Really like the the new “Device Dependency” function in LibreNMS, was a long-waited one. Found out that this feature lacked some visual representation, which I see as a must-have on big installations.
I have written a small plugin to have this functionality, maybe somebody will find it useful.
The plugin is based on the generic LibreNMS map module and at this point lacks some filtering (by device ID’s, or device groups), since i didn’t find a decent way to make it look nice.
