Types ¶
type Provider ¶
type Provider struct {
// contains filtered or unexported fields
}
Provider wraps a metrics.Metrics provider with a Prometheus registry that can instrument the HTTP server's handlers.
func New ¶
func New(inner metrics.Metrics, logger func(attrs map[string]interface{}, f string, a ...interface{})) *Provider
New returns a new Provider object.
func (*Provider) All ¶
All returns the union of the inner metric provider and the underlying prometheus registry.
func (*Provider) Clear ¶
func (p *Provider) Clear()
Clear resets the inner metric provider. The Prometheus registry does not expose an interface to clear the metrics so this call has no affect on metrics tracked by Prometheus.
func (*Provider) InstrumentHandler ¶
InstrumentHandler returned wrapped HTTP handler with added prometheus instrumentation
func (*Provider) MarshalJSON ¶
MarshalJSON returns a JSON representation of the unioned metrics.
func (*Provider) RegisterEndpoints ¶
RegisterEndpoints registers `/metrics` endpoint
