func WithConcurrentRequests Uses

func WithConcurrentRequests(n int) option

func WithLogger Uses

func WithLogger(logger log.Logger) option

func WithPercentiles Uses

func WithPercentiles(percentiles ...float64) option

WithPercentiles registers the percentiles to track, overriding the existing/default values. Reason is that Cloudwatch makes you pay per metric, so you can save half the money by only using 2 metrics instead of the default 4.

type CloudWatch Uses

type CloudWatch struct {
    // contains filtered or unexported fields
}

CloudWatch receives metrics observations and forwards them to CloudWatch. Create a CloudWatch object, use it to create metrics, and pass those metrics as dependencies to the components that will use them.

To regularly report metrics to CloudWatch, use the WriteLoop helper method.

func New Uses

func New(namespace string, svc cloudwatchiface.CloudWatchAPI, options ...option) *CloudWatch

New returns a CloudWatch object that may be used to create metrics. Namespace is applied to all created metrics and maps to the CloudWatch namespace. Callers must ensure that regular calls to Send are performed, either manually or with one of the helper methods.

func (*CloudWatch) NewCounter Uses

func (cw *CloudWatch) NewCounter(name string) metrics.Counter

NewCounter returns a counter. Observations are aggregated and emitted once per write invocation.

func (*CloudWatch) NewGauge Uses

func (cw *CloudWatch) NewGauge(name string) metrics.Gauge

NewGauge returns an gauge.

func (*CloudWatch) NewHistogram Uses

func (cw *CloudWatch) NewHistogram(name string) metrics.Histogram

NewHistogram returns a histogram.

func (*CloudWatch) Send Uses

func (cw *CloudWatch) Send() error

Send will fire an API request to CloudWatch with the latest stats for all metrics. It is preferred that the WriteLoop method is used.

func (*CloudWatch) WriteLoop Uses

func (cw *CloudWatch) WriteLoop(c <-chan time.Time)

WriteLoop is a helper method that invokes Send every time the passed channel fires. This method blocks until the channel is closed, so clients probably want to run it in its own goroutine. For typical usage, create a time.Ticker and pass its C channel to this method.

type Counter Uses

type Counter struct {
    // contains filtered or unexported fields
}

Counter is a counter. Observations are forwarded to a node object, and aggregated (summed) per timeseries.

func (*Counter) Add Uses

func (c *Counter) Add(delta float64)

Add implements metrics.Counter.

func (*Counter) With Uses

func (c *Counter) With(labelValues ...string) metrics.Counter

With implements metrics.Counter.

type Gauge Uses

type Gauge struct {
    // contains filtered or unexported fields
}

Gauge is a gauge. Observations are forwarded to a node object, and aggregated (the last observation selected) per timeseries.

func (*Gauge) Add Uses

func (g *Gauge) Add(delta float64)

Add implements metrics.Gauge.

func (*Gauge) Set Uses

func (g *Gauge) Set(value float64)

Set implements metrics.Gauge.

func (*Gauge) With Uses

func (g *Gauge) With(labelValues ...string) metrics.Gauge

With implements metrics.Gauge.

type Histogram Uses

type Histogram struct {
    // contains filtered or unexported fields
}

Histogram is an Influx histrogram. Observations are aggregated into a generic.Histogram and emitted as per-quantile gauges to the Influx server.

func (*Histogram) Observe Uses

func (h *Histogram) Observe(value float64)

Observe implements metrics.Histogram.

func (*Histogram) With Uses

func (h *Histogram) With(labelValues ...string) metrics.Histogram

With implements metrics.Histogram.

type Percentiles Uses

type Percentiles []struct {
    // contains filtered or unexported fields
}
