Constants

const (

	HABackendKubernetes = "kube"
)

Supported HA backend modes.

const ExtraArgsEnvvar = "EXTRA_ARGS"

Environment variable that contains additional command line arguments. It can be used to inject additional arguments when the regular ones cannot be easily modified.

Functions

func ExtraArgs

func ExtraArgs() ([]string, error)

ExtraArgs returns additional command line arguments extracted from the EXTRA_ARGS. environment variable. It is parsed like a shell parses arguments. For example: EXTRA_ARGS="--foo=bar -x 123". It can be used like `flagset.Parse(append(os.Args[1:], ExtraArgs()...))`.

func FromFlags

func FromFlags(a *kingpin.Application, userAgent string) func(log.Logger, prometheus.Registerer) (*export.Exporter, error)

FromFlags returns a constructor for a new exporter that is configured through flags that are registered with the given application. The constructor must be called after the flags have been parsed.

func Global

func Global() *export.Exporter

Global returns the global instance of the GCM exporter.

func SetGlobal

func SetGlobal(exporter *export.Exporter) (err error)

SetGlobal sets the global instance of the GCM exporter.
