var DefaultConfig = Config{
	Global:                 instance.DefaultGlobalConfig,
	InstanceRestartBackoff: 5 * time.Second,

	ServiceConfig:       cluster.DefaultConfig,

DefaultConfig is the default settings for the Prometheus-lite client.

Types

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.

func (*Config) ApplyDefaults

func (c *Config) ApplyDefaults() error

ApplyDefaults applies default values to the Config and validates it.

func (*Config) RegisterFlags

func (c *Config) RegisterFlags(f *flag.FlagSet)

RegisterFlags defines flags corresponding to the Config.

func (*Config) RegisterFlagsWithPrefix

func (c *Config) RegisterFlagsWithPrefix(prefix string, f *flag.FlagSet)

RegisterFlagsWithPrefix defines flags with the provided prefix.

func (*Config) UnmarshalYAML

func (c *Config) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements yaml.Unmarshaler.
