Fix PHP notice: Undefined index: samples #128

Closed pluk77 closed 9 months ago

pluk77 commented 11 months ago

collectHistograms() in the storage adapters does not define ['samples'] as the default array keys and as such a notice is thrown when the MetricFamilySamples::__construct($data) is called when no samples are available.
