Variables

var ErrRemoteStorageDisabled = fmt.Errorf("remote graphite storage is not enabled")

ErrRemoteStorageDisabled is used to prevent remote.Fetch calls when remote storage is disabled

Functions

func Create

func Create(config *Config) metricSource.MetricSource

Create configures remote metric source

Types

type Config

type Config struct {
	URL           string
	CheckInterval time.Duration
	Timeout       time.Duration
	User          string
	Password      string
	Enabled       bool
}

Config represents config from remote storage

type ErrRemoteTriggerResponse

type ErrRemoteTriggerResponse struct {
	InternalError error
	Target        string
}

ErrRemoteTriggerResponse is a custom error when remote trigger check fails

func (ErrRemoteTriggerResponse) Error

func (err ErrRemoteTriggerResponse) Error() string

Error is a representation of Error interface method

type FetchResult

type FetchResult struct {
	MetricsData []*metricSource.MetricData
}

FetchResult is implementation of metric_source.FetchResult interface, which represent fetching result from remote graphite installation in moira format

func (*FetchResult) GetMetricsData

func (fetchResult *FetchResult) GetMetricsData() []*metricSource.MetricData

GetMetricsData return all metrics data from fetch result

func (*FetchResult) GetPatternMetrics

func (*FetchResult) GetPatternMetrics() ([]string, error)

GetPatternMetrics always returns error, because remote fetch doesn't return base pattern metrics

func (*FetchResult) GetPatterns

func (*FetchResult) GetPatterns() ([]string, error)

GetPatterns always returns error, because we can't fetch target patterns from remote metrics source

type Remote

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

Remote is implementation of MetricSource interface, which implements fetch metrics method from remote graphite installation

func (*Remote) Fetch

func (remote *Remote) Fetch(target string, from, until int64, allowRealTimeAlerting bool) (metricSource.FetchResult, error)

Fetch fetches remote metrics and converts them to expected format

func (*Remote) IsConfigured

func (remote *Remote) IsConfigured() (bool, error)

IsConfigured returns false in cases that user does not properly configure remote settings like graphite URL

func (*Remote) IsRemoteAvailable

func (remote *Remote) IsRemoteAvailable() (bool, error)

IsRemoteAvailable checks if graphite API is available and returns 200 response
