Elasticsearch cluster status :

{
“cluster_name” : “elastic02”,
“status” : “green”,
“timed_out” : false,
“number_of_nodes” : 6,
“number_of_data_nodes” : 3,
“active_primary_shards” : 52,
“active_shards” : 52,
“relocating_shards” : 0,
“initializing_shards” : 0,
“unassigned_shards” : 0,
“delayed_unassigned_shards” : 0,
“number_of_pending_tasks” : 0,
“number_of_in_flight_fetch” : 0,
“task_max_waiting_in_queue_millis” : 0,
“active_shards_percent_as_number” : 100.0
}

What is the cause of that trouble ? How to fix it ?

If you need more information just let me know.

Thank you.

Any errors or warnings in the logs of your Graylog nodes?
Is “elastic02” the correct Elasticsearch cluster name?

I did not see anything in logs.
And elastic02 has always been the correct cluster, nothing changed recently.
