Has anyone used this tool? I've installed it and although it's still somewhat buggy, the functionality is very impressive. For someone running a relatively small and cheap cluster, this is a lifesaver!
If anyone has any success or horror stories regarding this plugin, I'd love to hear them! I'm not completely aware of the functionality provided through X-pack and watcher, but KaaE appears able to do everything I need.
I might sound like a shill, but I just love open-source and I have no affiliation with this plugin passed getting advice and submitting bugs/praise.
