	ContinuousQuery continuous_querier.Config `toml:"continuous_queries"`

	// Server reporting
	ReportingDisabled bool `toml:"reporting-disabled"`

	// BindAddress is the address that all TCP services use (Raft, Snapshot, Cluster, etc.)
	BindAddress string `toml:"bind-address"`
}

Config represents the configuration format for the influxd binary.

func NewConfig

func NewConfig() *Config

NewConfig returns an instance of Config with reasonable defaults.

func NewDemoConfig

func NewDemoConfig() (*Config, error)

	PIDFile    string
	CPUProfile string
	MemProfile string
}

Options represents the command line options that can be parsed.

func (*Options) GetConfigPath

func (opt *Options) GetConfigPath() string
