These parameters can be defined seperately or +in combination. + +Reading Metric Data +------------------- +To define what metric data you want to read from the Gnocchi database a no. of +parameters have to be defined: + +* Metric_uuid: To define which metric's data you would like to read. +* Collection_unit: Defines the unit of time that you want to read the metric + data over. + + .. note:: + + + The units that you can define include: HR, DAY, WEEK, MONTH, YEAR. + +* Collection_period: defines the integer value of the collection period. + E.g. 1 DAY. + +This type of request results in a list of data values and a corresponding list +of timestamps.
