Functions

func CheckSecret

func CheckSecret(t *testing.T, rawCfg string, originalValue string)

CheckSecret is a helper function to ensure the original value is overwritten with <secret>

func LoadBytes

func LoadBytes(buf []byte, expandEnvVars bool, c *Config) error

LoadBytes unmarshals a config from a buffer. Defaults are not applied to the file and must be done manually if LoadBytes is called directly.

func LoadFile

func LoadFile(filename string, expandEnvVars bool, c *Config) error

LoadFile reads a file and passes the contents to Load

func LoadRemote

func LoadRemote(url string, expandEnvVars bool, c *Config) error

LoadRemote reads a config from url

	EnabledFeatures   []string `yaml:"-"`
}

Config contains underlying configurations for the agent

func DefaultConfig

func DefaultConfig() Config

DefaultConfig holds default settings for all the subsystems.

func Load

func Load(fs *flag.FlagSet, args []string, log *server.Logger) (*Config, error)

Load loads a config file from a flagset. Flags will be registered to the flagset before parsing them with the values specified by args.

func LoadFromFunc

func LoadFromFunc(fs *flag.FlagSet, args []string, loader loaderFunc) (*Config, error)

LoadFromFunc injects a function for retrieving the config file that doesn't require having a literal file on disk.

func (*Config) LogDeprecations

func (c *Config) LogDeprecations(l log.Logger)

LogDeprecations will log use of any deprecated fields to l as warn-level messages.

func (Config) MarshalYAML

func (c Config) MarshalYAML() (interface{}, error)

MarshalYAML implements yaml.Marshaler.

func (*Config) RegisterFlags

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

RegisterFlags registers flags in underlying configs

func (*Config) UnmarshalYAML

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

UnmarshalYAML implements yaml.Unmarshaler.

func (*Config) Validate

func (c *Config) Validate(fs *flag.FlagSet) error

Validate validates the config, flags, and sets default values.

type Integrations

type Integrations interface {
	ApplyConfig(*VersionedIntegrations, IntegrationsGlobals) error
	WireAPI(*mux.Router)
	Stop()
}

Integrations is an abstraction over both the v1 and v2 systems.

func NewIntegrations

func NewIntegrations(logger log.Logger, cfg *VersionedIntegrations, globals IntegrationsGlobals) (Integrations, error)

NewIntegrations creates a new subsystem. globals should be provided regardless of useV2. globals.SubsystemOptions will be automatically set if cfg.Version is set to IntegrationsVersion2.

type IntegrationsGlobals

type IntegrationsGlobals = v2.Globals

IntegrationsGlobals is a global struct shared across integrations.

type RemoteConfig

type RemoteConfig struct {
	BaseConfig BaseConfigContent `json:"base_config" yaml:"base_config"`
