Types ¶
type LazyGauge ¶
type LazyGauge struct {
// contains filtered or unexported fields
}
LazyGauge registers its underlying Gauge the first time Set is called. This avoids exposing a default zero value before we have an appropriate value to expose.
func NewLazyGauge ¶
func NewLazyGauge( registerer prometheus.Registerer, logger commontypes.Logger, opts prometheus.GaugeOpts, ) *LazyGauge
func (*LazyGauge) Unregister ¶
Unregister must be used instead of prometheus.Registerer.Unregister. Otherwise, it would be possible for the LazyGauge to have never been Set and thus registered, and then after invocation of prometheus.Registerer.Unregister, the next Set would cause the gauge to be registered, which is almost definitely unexpected behavior. In fact, LazyGauge intentionally does not implement prometheus.Collector to avoid confusion. The meaning of the return value matches that of prometheus.Registerer.Unregister.
type PrometheusRegistererWrapper ¶
type PrometheusRegistererWrapper struct {
// contains filtered or unexported fields
}
func NewPrometheusRegistererWrapper ¶
func NewPrometheusRegistererWrapper(registerer prometheus.Registerer, logger commontypes.Logger) *PrometheusRegistererWrapper
func (*PrometheusRegistererWrapper) MustRegister ¶
func (prw *PrometheusRegistererWrapper) MustRegister(collectors ...prometheus.Collector)
func (*PrometheusRegistererWrapper) Register ¶
func (prw *PrometheusRegistererWrapper) Register(collector prometheus.Collector) error
func (*PrometheusRegistererWrapper) Unregister ¶
func (prw *PrometheusRegistererWrapper) Unregister(collector prometheus.Collector) bool
