Types

type Config

type Config struct {
	config.ObserverConfig
	DockerURL string `yaml:"dockerURL" default:"unix:///var/run/docker.sock"`
	// A mapping of container label names to dimension names that will get
	// applied to the metrics of all discovered services. The corresponding
	// label values will become the dimension values for the mapped name.  E.g.
	// `io.kubernetes.container.name: container_spec_name` would result in a
	// dimension called `container_spec_name` that has the value of the
	// `io.kubernetes.container.name` container label.
	LabelsToDimensions map[string]string `yaml:"labelsToDimensions"`
	// If true, the "Config.Hostname" field (if present) of the docker
	// container will be used as the discovered host that is used to configure
	// monitors.  If false or if no hostname is configured, the field
	// `NetworkSettings.IPAddress` is used instead.
	UseHostnameIfPresent bool `yaml:"useHostnameIfPresent"`
	// If true, the observer will configure monitors for matching container endpoints
	// using the host bound ip and port.  This is useful if containers exist that are not
	// accessible to an instance of the agent running outside of the docker network stack.
	UseHostBindings bool `yaml:"useHostBindings" default:"false"`
	// If true, the observer will ignore discovered container endpoints that are not bound
	// to host ports.  This is useful if containers exist that are not accessible
	// to an instance of the agent running outside of the docker network stack.
	IgnoreNonHostBindings bool `yaml:"ignoreNonHostBindings" default:"false"`
}
