Config controls kafka_exporter

func (*Config) InstanceKey added in v0.21.0

func (c *Config) InstanceKey(agentKey string) (string, error)

InstanceKey returns the hostname:port of the first Kafka node, if any. If there is not exactly one Kafka node, the user must manually provide their own value for instance key in the common config.

func (*Config) Name

func (c *Config) Name() string

Name returns the name of the integration that this config represents.

func (*Config) NewIntegration

func (c *Config) NewIntegration(logger log.Logger) (integrations.Integration, error)

NewIntegration creates a new elasticsearch_exporter

func (*Config) UnmarshalYAML

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

UnmarshalYAML implements yaml.Unmarshaler for Config
