Hi Team,

I need to add additional data node to my existing cluster.  
at present i have 3-master, 2-data, 2-kibana, 3-logstash. with 1-replica & 5-shard config. i am sending  
I would like to additional 4 nodes to the existing cluster for performance.  
Please help me in calculating the shards per indexes and

May I suggest you look at the following resources about sizing:

> **[Quantitative Cluster Sizing](https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing)**

> **[How many shards should I have in my Elasticsearch cluster?](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster)**
