Hi,  
I'm using Flume+ES+Kibana

ES and Kibana works fine, but log can't transfer through,

On Flume side,  
20:29:54.061 INFO org.elasticsearch.client.transport.TransportClientNodesService$SimpleNodeSampler 414 doSample - failed to get node info for {#transport#-1}{wTwOY6pmSxuA871QKKKUwQ}{10.88.126.172}{10.88.126.172:9300}, disconnecting... org.elasticsearch.transport.RemoteTransportException: [fca-vm-search-log][10.88.126.172:9300][cluster:monitor/nodes/liveness]  
Caused by: org.elasticsearch.ElasticsearchSecurityException: missing authentication token for action [cluster:monitor/nodes/liveness]  
at org.elasticsearch.xpack.security.support.Exceptions.authenticationError(Exceptions.java:39) ~[?:?]

Does anyone has experience how authenticate flume connecting with X-Pack, thanks in advance.

Larry

Hey,

have you configured the transport client on the flume side to contain username/password? I suppose you have security enabled on your cluster?
