Functions

func Decorate

func Decorate(cloudProvider cloudprovider.CloudProvider) cloudprovider.CloudProvider

Decorate returns a new `CloudProvider` instance that will delegate all method calls to the argument, `cloudProvider`, and publish aggregated latency metrics. The value used for the metric label, "controller", is taken from the `Context` object passed to the methods of `CloudProvider`.

Do not decorate a `CloudProvider` multiple times or published metrics will contain duplicated method call counts and latencies.

func GetErrorTypeLabelValue

func GetErrorTypeLabelValue(err error) string

GetErrorTypeLabelValue is a convenience func that returns a string representation of well-known CloudProvider error types
