var ErrNoData = errors.New("collector returned no data")

ErrNoData indicates the collector found no data to collect, but had no other error.

Functions

func DisableDefaultCollectors 

func DisableDefaultCollectors()

DisableDefaultCollectors sets the collector state to false for all collectors which have not been explicitly enabled on the command line.

func IsNoDataError 

func IsNoDataError(err error) bool

func SanitizeMetricName 

func SanitizeMetricName(metricName string) string

SanitizeMetricName sanitize the given metric name by replacing invalid characters by underscores.

OpenMetrics and the Prometheus exposition format require the metric name to consist only of alphanumericals and "_", ":" and they must not start with digits. Since colons in MetricFamily are reserved to signal that the MetricFamily is the result of a calculation or aggregation of a general purpose monitoring system, colons will be replaced as well.

Note: If not subsequently prepending a namespace and/or subsystem (e.g., with prometheus.BuildFQName), the caller must ensure that the supplied metricName does not begin with a digit.
