Elasticsearch 7 Quick Start Guide

Avg aggregation

This is a single-value metric aggregation that computes the average of numeric values. The values are extracted from the aggregated document fields or from a script. For example, let's say we want to average the price of a range of backpacks in a store:

POST /backpack/_search?size=0{  "aggs": {    "avg_price": {      "avg": {        "field": "price"      }    }  }}

The preceding expression shows an example of the avg aggregation, where we are applying the avg aggregation to the price field.
