Team,

Looking for a right metric to determine which cluster is taking read traffic. We have 2 clusters for redundancy at anytime only one cluster will take read traffic anc both takes write traffic.

I have been playing with metrics like query\_current from \_nodes/stats/indices/search , \_nodes/stats/thread\_pool?pretty=true | jq -r '.nodes | . | .thread\_pool.search.active'.  
All these gives me similar data. Is there a metric that clearly states reads or application read queries are routed in clusterA or B.

Hello @mannoj87

As per the documentation

> **[Nodes stats API](https://www.elastic.org.cn/docs/8.1/www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html)**

Can we try to use below :

```auto
GET /_nodes/stats/indices/search?filter_path=cluster_name,nodes.*.indices.search.*

```

query\_current  
query\_total

Thanks!!

Yes tried it, in both clusters I see numbers like

cluster1 : query\_current=9

cluster2 : query\_current=10

The value is sum of all data and query nodes falling under {indices.search.query\_current}.
