=== Metric Functions
|
|
|
|
|
|
|
|
|
|
The {xpackml} features include the following metric functions:
|
|
|
|
|
|
|
|
|
|
* `min`
|
|
|
|
|
* `max`
|
|
|
|
|
* `mean`, `high_mean`, `low_mean`
|
|
|
|
|
* `metric`
|
|
|
|
|
* `varp`, `high_varp`, `low_varp`
|
|
|
|
|
|
|
|
|
|
The metric functions include mean, min and max. These values are calculated for each bucket.
|
|
|
|
|
Field values that cannot be converted to double precision floating point numbers
|
|
|
|
|
are ignored.
