Whiteboard:
Fixed In Version: openshift3/logging-fluentd:v3.9.41-1 Doc Type: Enhancement
Doc Text:
Feature: Fluentd will now reconnect to Elasticsearch every 100 operations by default. Reason: If one Elasticsearch is started before the others in the cluster, the load balancer in the Elasticsearch service will connect to that one and that one only, and so will all of the Fluentd connecting to Elasticsearch. Result: By having Fluentd reconnect periodically, the load balancer will be able to spread the load evenly among all of the Elasticsearch in the cluster.
