Which node types need the Watcher plugin?

Hello all,

In a split role cluster, which node types need the Watcher plugin installed? Masters/Clients/Data, or some combination of the three?

Many thanks!

Watcher and the license plugin need to be installed on all nodes. Otherwise on client nodes that don't have watcher installed, api calls will not be forwarded correctly.

Thanks for the reply, Martjin.
That's what I had done to be safe. Glad to know that's the way it should
be.
