Functions

func GetLocalHost

func GetLocalHost() string

GetLocalHost returns the DOCKER_HOST environment variable, parsing out any scheme or ports so that only the IP address is returned.

func MockMetrics

func MockMetrics() []telegraf.Metric

MockMetrics returns a mock []telegraf.Metric object for using in unit tests of telegraf output sinks.

func TestMetric

func TestMetric(value interface{}, name ...string) telegraf.Metric

TestMetric Returns a simple test point:

measurement -> "test1" or name
tags -> "tag1":"value1"
value -> value
time -> time.Date(2009, time.November, 10, 23, 0, 0, 0, time.UTC)

Types

type Accumulator

type Accumulator struct {
	sync.Mutex

	Metrics []*Metric

	Discard bool
	Errors  []error
	// contains filtered or unexported fields
}

Accumulator defines a mocked out accumulator

)

func (*Accumulator) AddError

func (a *Accumulator) AddError(err error)

AddError appends the given error to Accumulator.Errors.

func (*Accumulator) AddFields

func (a *Accumulator) AddFields(
	measurement string,
	fields map[string]interface{},
	tags map[string]string,
	timestamp ...time.Time,
)

AddFields adds a measurement point with a specified timestamp.
