Kibana monitoring showing wrong number of instances

I had a server running Kibana, then I set up Kibana on a different server and shut down the previous instance. However, when I go to "Monitoring" in Kibana, it still lists the old instance. It does show it is offline, but I don't want it there anymore.

How can I remove it?

If you want it removed removed you can do a delete by query on the .monitoring-kibana-* indices, with something unique like the uuid.

Does changing the time range in the top right help? An instance will show "offline" if it's within the time range, but I believe it will be removed if it's no longer within the allotted time.

That worked. Thanks!
