Hello everyone
Tell me pliz, who knows how to get the discovery.zen.ping.unicast.hosts parameter through the apishka?
You can do this via GET _nodes, but you need to parse the json with nodes in a loop and pull out the desired key. Not very comfortable. Maybe there is some kind of get request that vzhuh and immediately returned a list?
Google and the documentation haven't been very helpful so far.
