0.2.0

Google Stackdriver Prometheus Exporter v0.2.0:

This release introduces a breaking change w/r/t metric's names & labels:

• Metric's names are normalized according to the Prometheus specification using the following pattern:
  1. namespace is a constant prefix (stackdriver)
  2. subsystem is the normalized monitored resource type (ie gce_instance)
  3. name is the normalized metric type (ie compute_googleapis_com_instance_cpu_usage_time)
• Labels attached to each metric are an aggregation of:
  1. the unit in which the metric value is reported
  2. the metric type labels (see Metrics List)
  3. the monitored resource labels (see Monitored Resource Types)
