Types

type Config

type Config struct {
	// VictoriaMetrics address to perform import requests
	//   --httpListenAddr value for single node version

	Addr string
	// Concurrency defines number of worker
	// performing the import requests concurrently
	Concurrency uint8
	// Whether to apply gzip compression
	Compress bool
	// AccountID for cluster version.
	// Empty value assumes it is a single node version
	AccountID string
	// BatchSize defines how many samples
	// importer collects before sending the import request
	BatchSize int
	// User name for basic auth
	User string
	// Password for basic auth
	Password string
	// SignificantFigures defines the number of significant figures to leave
	// in metric values before importing.
	// Zero value saves all the significant decimal places
	SignificantFigures int
	// RoundDigits defines the number of decimal digits after the point that must be left
	// in metric values before importing.
	RoundDigits int
	// ExtraLabels that will be added to all imported series. Must be in label=value format.
	ExtraLabels []string
