Overview

The conversion functions take a key and a map[string]string. First it checks if the key exists and logs and error if this is not the case. Second the conversion to the type is done. In case of an error and error is logged and the default values is returned. This guarantees that also if a field is missing or is not defined, still the full metricset is returned.

Package helper contains helper functions to make it simpler to perform common tasks and implement common features in Modules and MetricSets.
