Event Service health keeps turning critical

Event Service health keeps turning critical



I have a problem whereby my events service health keeps turning to critical after awhile even when i restarted it. Whenever I restart the events service, it goes back to healthy but after awhile, it jumps back to critical again.


I went through the logs and saw multiple errors and is caused by:

"Caused by: org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{}{}]
at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(
at org.elasticsearch.client.transport.TransportClientNodesService.execute(
at org.elasticsearch.client.transport.TransportClient.doExecute(
at org.elasticsearch.action.ActionRequestBuilder.execute(
at org.elasticsearch.action.ActionRequestBuilder.execute(


How do I resolve this? Thanks in advance

Event Service health keeps turning critical

Hello Alan,

I got the same issue and after checking the documentation 


we should scale up events service as long as we run it as a single node especially in the dev & test environment however it's recommended to use a cluster of multi-nodes in a production environment
