unless you change the token, which would impact all nodes, you can't.You can use the mapping tab to put it in an "inactive" group

stopping Edge on the node will also make it drop from the Leader listing

What if the instance is terminated?

the node will only show on the leader while it's actively connected to the leader

if the instance is dead, or the process stops running, it will disappear

interesting, seems like there’s some sort of bug as there are a number of terminated instances which still appear in the UI

any chance you cloned installs? if a node has a dupe GUID with another, you're going to see that GUID still alive

yeah that looks to be the issue.. How do we resolve this?

You can stop Edge, remove the dat file, then restart. It will create a fresh guid

$ cat /opt/cribl/local/cribl/auth/676f6174733432.dat{"it":1650381948,"phf":0,"guid":"55daf1ef-31aa-42b8-9fab-1fe62e7f2966","lics":["license-free-3.5.3-RC3-08986e05"]}
