type Config ¶

type Config struct {
	Global                 instance.GlobalConfig `yaml:"global,omitempty"`
	WALDir                 string                `yaml:"wal_directory,omitempty"`
	WALCleanupAge          time.Duration         `yaml:"wal_cleanup_age,omitempty"`
	WALCleanupPeriod       time.Duration         `yaml:"wal_cleanup_period,omitempty"`
	ServiceConfig          cluster.Config        `yaml:"scraping_service,omitempty"`
	ServiceClientConfig    client.Config         `yaml:"scraping_service_client,omitempty"`
	Configs                []instance.Config     `yaml:"configs,omitempty"`
	InstanceRestartBackoff time.Duration         `yaml:"instance_restart_backoff,omitempty"`
	InstanceMode           instance.Mode         `yaml:"instance_mode,omitempty"`
	DisableKeepAlives      bool                  `yaml:"http_disable_keepalives,omitempty"`
	IdleConnTimeout        time.Duration         `yaml:"http_idle_conn_timeout,omitempty"`

	// Unmarshaled is true when the Config was unmarshaled from YAML.
	Unmarshaled bool `yaml:"-"`
}

Config defines the configuration for the entire set of Prometheus client instances, along with a global configuration.
