+Commands:
+  create [projectId]                       Creates an example 'custom.googleapis.com/stores/daily_sales' custom metric
+                                           descriptor.
+  list [projectId]                         Lists metric descriptors.
+  get <metricId> [projectId]               Get a metric descriptor.
+  delete <metricId> [projectId]            Deletes a custom metric descriptor.
+  write [projectId]                        Writes example time series data to
+                                           'custom.googleapis.com/stores/daily_sales'.
+  read <filter> [projectId]                Reads time series data that matches the given filter.
+  read-fields [projectId]                  Reads headers of time series data that matches
+                                           'compute.googleapis.com/instance/cpu/utilization'.
+  read-aggregate [projectId]               Aggregates time series data that matches

+  read-reduce [projectId]                  Reduces time series data that matches
+                                           'compute.googleapis.com/instance/cpu/utilization'.
+  list-resources [projectId]               Lists monitored resource descriptors.
+  get-resource <resourceType> [projectId]  Get a monitored resource descriptor.

+Options:
+  --help           Show help                                                                                   [boolean]
