func MakeAndRegister ¶
func MakeAndRegister(gatherer MultiGatherer, name string) (metric.Registry, error)
Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client for requesting metrics from a remote Lux Node instance
func (*Client) GetMetrics ¶
GetMetrics returns the metrics from the connected node. The metrics are returned as a map of metric family name to the metric family.
type MultiGatherer ¶
type MultiGatherer interface {
metric.Gatherer
// Register adds the outputs of [gatherer] to the results of future calls to
// Gather with the provided [name] added to the metrics.
Register(name string, gatherer metric.Gatherer) error
// Deregister removes the outputs of a gatherer with [name] from the results
// of future calls to Gather. Returns true if a gatherer with [name] was
// found.
Deregister(name string) bool
}
MultiGatherer extends the Gatherer interface by allowing additional gatherers to be registered.
func NewLabelGatherer ¶
func NewLabelGatherer(labelName string) MultiGatherer
NewLabelGatherer returns a new MultiGatherer that merges metrics by adding a new label.
func NewMultiGatherer ¶
func NewMultiGatherer() MultiGatherer
NewMultiGatherer creates and returns a new MultiGatherer that applies prefixes to metric names. For a MultiGatherer without prefix support, use the multiGatherer struct directly.
func NewPrefixGatherer ¶
func NewPrefixGatherer() MultiGatherer
NewPrefixGatherer returns a new MultiGatherer that merges metrics by adding a prefix to their names.
type OptionalGatherer ¶
type OptionalGatherer interface {
metric.Gatherer
// Register the provided gatherer. If a gatherer was previously registered,
// an error will be returned.
Register(gatherer metric.Gatherer) error
}
OptionalGatherer extends the Gatherer interface by allowing the optional registration of a single gatherer. If no gatherer is registered, Gather will return no metrics and no error. If a gatherer is registered, Gather will return the results of calling Gather on the provided gatherer.
func NewOptionalGatherer ¶
func NewOptionalGatherer() OptionalGatherer
