Types

type Broker

type Broker struct {
	Config      *sarama.Config
	JMXPort     int
	JMXUser     string
	JMXPassword string
	Host        string
	ID          string
	SaramaBroker
}

Broker is a struct containing all the information to collect from both Kafka and from JMX

func GetBrokerFromZookeeper

func GetBrokerFromZookeeper(zkConn zookeeper.Connection, id, preferredListener string) (*Broker, error)

GetBrokerFromZookeeper gets a broker with given ID from zookeeper

func GetBrokerListFromZookeeper

func GetBrokerListFromZookeeper(zkConn zookeeper.Connection, preferredListener string) ([]*Broker, error)

GetBrokerListFromZookeeper gets a list of brokers from zookeeper

func NewBroker

func NewBroker(brokerArgs *args.BrokerHost) (*Broker, error)

NewBroker creates a new broker

func (*Broker) Entity

func (b *Broker) Entity(i *integration.Integration) (*integration.Entity, error)

Entity gets the entity object for the broker

type Client

type Client interface {
	Config() *sarama.Config
	Controller() (*sarama.Broker, error)
	Brokers() []*sarama.Broker
	Topics() ([]string, error)
	Partitions(topic string) ([]int32, error)
	WritablePartitions(topic string) ([]int32, error)
	Leader(topic string, partitionID int32) (*sarama.Broker, error)

	RefreshMetadata(topics ...string) error
	GetOffset(topic string, partitionID int32, time int64) (int64, error)
	Coordinator(consumerGroup string) (*sarama.Broker, error)
	RefreshCoordinator(consumerGroup string) error
	RefreshController() (*sarama.Broker, error)
	InitProducerID() (*sarama.InitProducerIDResponse, error)
	Close() error

}

Client is a wrapper around sarama.Client so that we can generate mocks See sarama.Client for documentation
