Functions ¶
func RegisterStatsSender ¶
func RegisterStatsSender(sender StatsTelemetrySender)
RegisterStatsSender regsiters a sender to send the stats metrics
Types ¶
type Counter ¶
type Counter interface {
telemetryComponent.Counter
}
Counter tracks how many times something is happening.
func NewCounter ¶
NewCounter creates a Counter with default options for telemetry purpose. Current implementation used: Prometheus Counter
type Gauge ¶
type Gauge interface {
telemetryComponent.Gauge
}
Gauge tracks the value of one health metric of the Agent.
type Histogram ¶
type Histogram interface {
telemetryComponent.Histogram
}
Histogram tracks the value of one health metric of the Agent.
func NewHistogram ¶
NewHistogram creates a Histogram with default options for telemetry purpose. Current implementation used: Prometheus Histogram
func NewHistogramNoOp ¶
func NewHistogramNoOp() Histogram
NewHistogramNoOp creates a dummy Histogram
type Options ¶
type Options telemetryComponent.Options
Options for telemetry metrics. Creating an Options struct without specifying any of its fields should be the equivalent of using the DefaultOptions var.
var DefaultOptions Options = Options(telemetryComponent.DefaultOptions)
DefaultOptions for telemetry metrics which don't need to specify any option.
type SimpleCounter ¶
type SimpleCounter interface {
telemetryComponent.SimpleCounter
}
SimpleCounter tracks how many times something is happening.
func NewSimpleCounter ¶
func NewSimpleCounter(subsystem, name, help string) SimpleCounter
NewSimpleCounter creates a new SimpleCounter with default options.
func NewSimpleCounterWithOpts ¶
func NewSimpleCounterWithOpts(subsystem, name, help string, opts Options) SimpleCounter
NewSimpleCounterWithOpts creates a new SimpleCounter.
type SimpleGauge ¶
type SimpleGauge interface {
telemetryComponent.SimpleGauge
}
SimpleGauge tracks how many times something is happening.
func NewSimpleGauge ¶
func NewSimpleGauge(subsystem, name, help string) SimpleGauge
NewSimpleGauge creates a new SimpleGauge with default options.
func NewSimpleGaugeWithOpts ¶
func NewSimpleGaugeWithOpts(subsystem, name, help string, opts Options) SimpleGauge
NewSimpleGaugeWithOpts creates a new SimpleGauge.
type SimpleHistogram ¶
type SimpleHistogram interface {
telemetryComponent.SimpleHistogram
}
SimpleHistogram tracks how many times something is happening.
func NewSimpleHistogram ¶
func NewSimpleHistogram(subsystem, name, help string, buckets []float64) SimpleHistogram
NewSimpleHistogram creates a new SimpleHistogram with default options.
func NewSimpleHistogramWithOpts ¶
func NewSimpleHistogramWithOpts(subsystem, name, help string, buckets []float64, opts Options) SimpleHistogram
NewSimpleHistogramWithOpts creates a new SimpleHistogram.
type StatCounterWrapper ¶ added in v0.52.0
type StatCounterWrapper struct {
// contains filtered or unexported fields
}
StatCounterWrapper is a convenience type that allows for migrating telemetry to prometheus Counters while continuing to make the underlying values available for reading
func NewStatCounterWrapper ¶ added in v0.52.0
func NewStatCounterWrapper(subsystem string, statName string, tags []string, description string) *StatCounterWrapper
NewStatCounterWrapper returns a new StatCounterWrapper
func (*StatCounterWrapper) Add ¶ added in v0.52.0
func (sgw *StatCounterWrapper) Add(v int64, tags ...string)
Add adds the given value to the counter with the given tags value.
func (*StatCounterWrapper) Delete ¶ added in v0.52.0
func (sgw *StatCounterWrapper) Delete()
Delete deletes the value for the counter with the given tags value.
func (*StatCounterWrapper) Inc ¶ added in v0.52.0
func (sgw *StatCounterWrapper) Inc(tags ...string)
Inc increments the counter with the given tags value.
func (*StatCounterWrapper) Load ¶ added in v0.52.0
func (sgw *StatCounterWrapper) Load() int64
Load atomically loads the wrapped value.
type StatGaugeWrapper ¶ added in v0.52.0
type StatGaugeWrapper struct {
// contains filtered or unexported fields
}
StatGaugeWrapper is a convenience type that allows for migrating telemetry to prometheus Gauges while continuing to make the underlying values available for reading
func NewStatGaugeWrapper ¶ added in v0.52.0
func NewStatGaugeWrapper(subsystem string, statName string, tags []string, description string) *StatGaugeWrapper
NewStatGaugeWrapper returns a new StatGaugeWrapper
func (*StatGaugeWrapper) Add ¶ added in v0.52.0
func (sgw *StatGaugeWrapper) Add(v int64)
Add adds the value to the Gauge value.
func (*StatGaugeWrapper) Dec ¶ added in v0.52.0
func (sgw *StatGaugeWrapper) Dec()
Dec decrements the Gauge value.
func (*StatGaugeWrapper) Inc ¶ added in v0.52.0
func (sgw *StatGaugeWrapper) Inc()
Inc increments the Gauge value.
func (*StatGaugeWrapper) Load ¶ added in v0.52.0
func (sgw *StatGaugeWrapper) Load() int64
Load atomically loads the wrapped value.
func (*StatGaugeWrapper) Set ¶ added in v0.52.0
func (sgw *StatGaugeWrapper) Set(v int64)
Set stores the value for the given tags.
type StatsTelemetryProvider ¶
type StatsTelemetryProvider struct {
