Hello,

Looks like your other two node are not processing any messages “0”.
Not sure what you have done or how you configured your cluster, so its hard to identify where the issue is.
What documentation did you use to create this cluster?
Perhaps some more information would help, if your unsure please look here for a better understanding.

Hello,

Not sure what configuration that is for, so I assume it elasticsearch. If that correct I see why your having problems, I’m also referring to package install. If this is Docker I’m not going to be much help.

I installed it with yum. There are currently 3 nodes. I want to use a haproxy to load balance the traffic. How to configure it? Now the traffic goes to the master node. The other two nodes are in restricted state, which leads to a backlog of messages on the master node.

You may need to read this documentation, It will explain how to set that up for you.
