I have a search head cluster setup and was wondering if I could set up a bulletin message (or any message really) that will contact all users regardless of what host in the cluster that they are on. I'm not sure if this is possible. I already tried doing this using a bulletin message but that didn't seem to work.
Interested in having a solution for this as well, I haven't tried it myself. But you should be able to just curl it from one machine to to all other cluster members machines as long as you are able to authenticate yourself. It feels like there should be an easier option out there, there might be a REST endpoint for updating this?
