KPIs

The kpis field in a study specifies which metrics should be considered as KPI for an offline optimization study.

In case this selection is not specified, all metrics mentioned in the goal and constraint of the optimization study are considered.

A KPI is defined as follows:

Field	Type	Value restriction	Is required	Default value	Description
name	string	should match a component metric	no	<metric_name>	Label that will be used in the UI
formula	string	Must be defined as <component_name>.<metric_name>	yes		The metric name associated to a component
direction	string	minimize, maximize	yes		The direction corresponding to the metric
aggregation	string	min, max, avg, sum, p95, ...	no	avg	A valid metric aggregation

Notice that the textual badge displayed in the Akamas UI use "Best name".
