Zombie windows nodes in Netdata dashboard

I have a Netdata parent server collecting metrics from several MS Windows servers. The parent has been been reconfigured several times, specifically the vnodes.conf file. Each time new GUIDs have been assigned to the Windows host names.

I now see the same Windows host names appearing 6 times in the nodes list in the Netdata dashboard. If I look at the info for each in JSON format I see only one uses the current GUID, the rest are the old ones.

I’ve deleted the Netdata cache, the database and even removed Windows node monitoring completely from the parent … and these zombie Windows nodes just keep reappearing in the dashboard, with status LIVE!

Where does the dashboard pull this information from and how do I get rid of these ghosts?

Hey, @andrewlove. Use netdatacli remove-stale-node command. See netdatacli help (located at the same dir as the netdata binary).

Hi @ilyam8
I trie that but all the duplicates are considered “live” so I get:

sudo netdatacli remove-stale-node 81fc7ca6-6728-8594-bb02-96b14fd1aab7
Cannot unregister a live node

@ilyam8 I really don’t know where it could be picking up these old GUDs from. I thought I’d cleared everything out.
