                                Map<String,?> metrics)

Convert plain key value map into a Kura metric structure
Only the supported Kura values types must be used (String, boolean, int, long, float, double, byte[])

Parameters:

builder - the builder to append the metrics to

metrics - the metrics map

Throws:

IllegalArgumentException - in case of an unsupported value type
