# Value count aggregations
|
|
|
|
The `value_count` metric is a single-value metric aggregation that calculates the number of values that an aggregation is based on.
|
|
|
|
For example, you can use the `value_count` metric with the `avg` metric to find how many numbers the aggregation uses to calculate an average value.
