Serveur status RED

Elastic Stack Elasticsearch
1

Hi
When i run :

GET /_cluster/health

I can see that the cluster is RED :

{
"cluster_name" : "es-monit-cluster",
"status" : "red",
"timed_out" : false,
"number_of_nodes" : 7,
"number_of_data_nodes" : 5,
"active_primary_shards" : 1641,
"active_shards" : 3382,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 2,
"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" : 99.94089834515366
}

So when i try :

GET /_cat/indices

I can see that the only RED index is :

green open .monitoring-es-7-2022.08.19 -zEIzgiJRIi-XOYtzFXQUw 1 1 13166291 560425 9.2gb 4.6gb

Can i delete this red index without damaging the cluster ?
Thanks

Yes you can.

But please note that you are perhaps overloading your cluster here and that the problem might happen again later.
