Metric aggregations

Metric aggregations let you perform simple calculations such as finding the minimum, maximum, and average values of a field.

Types of metric aggregations

There are two types of metric aggregations: single-value metric aggregations and multi-value metric aggregations.

Single-value metric aggregations

Single-value metric aggregations return a single metric, for example, sum, min, max, avg, cardinality, or value_count.

Multi-value metric aggregations

Multi-value metric aggregations return more than one metric. These include stats, extended_stats, matrix_stats, percentile, percentile_ranks, geo_bound, top_hits, and scripted_metric.
