Hi Team

I am using ES 7.17.1. Pushing logs from Fluent to 5 node cluster. Enabled xpack monitoring on ES. we observe that sometime during the day the indexing requests & indexing time goes very high on a single node. Sometimes, the indexing count is same on all nodes, but 1 of the node takes high indexing time leading to cpu saturation and wait queue.

How can I find out which indexes are getting more requests on a particular node and what it the RCA for slow indexing speed.

below is the setting in index template

```auto
"number_of_shards": "5",
"number_of_replicas": "0"
"routing": {
      "allocation": {
        "total_shards_per_node": "1"
      }
    },

```

What do the logs on that node show - Elasticsearch and slow log?  
What is the output from the [`_cluster/stats?pretty&human` API](https://www.elastic.co/guide/en/elasticsearch/reference/8.4/cluster-stats.html)?
