Metrics aggregations

The metrics aggregation family computes metrics based on values collected from the aggregated documents. Numeric metrics aggregations are a special kind of metrics aggregations that output numeric values. single-value numeric aggregations are aggregations that output a single numeric metric, and multi-value numeric metrics aggregations return multiple metrics. This is an important distinction when the aggregations are used as a sub-aggregation within a bucket aggregation. The following are some of the main metrics aggregation types:

• Avg aggregation
• Weighted avg aggregation
• Cardinality aggregation
• Extended stats aggregation
• Max aggregation
• Min aggregation
• Scripted metric aggregation
• Stats aggregation
• Sum aggregation
