Kibana reporting error ":["error","plugins","reporting"],"pid":6376,"message":"{ Error: [validation\_exception] Validation Failed: 1: this action would add [2] total shards, but this cluster currently has [3000]/[3000] maximum shards open

Hi @mbathann,

Welcome to the community! Which version of Elasticsearch and Kibana are you using?

It looks like your cluster has too many shards and you're hitting the limit. Can you check the size of your shards using the [`_cluster/stats` API](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-stats.html). I would also consider using the [`_shrink` API](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-shrink-index.html) as per [this old thread](https://discuss.elastic.co/t/validation-failed-1-this-action-would-add-2-total-shards-but-this-cluster-currently-has-2000-2000-maximum-shards-open/257064).

Hope that helps!

Hi,

You can increase the maximum number of open shards in your cluster by updating the cluster.max\_shards\_per\_node setting. However, be aware that having too many shards can lead to performance issues, so it's important to find a balance that works for your specific use case.

Regards
