FIELD: kafka <Object>


DESCRIPTION:
    Kafka configures forwarding log events to Apache Kafka topics
    
FIELDS:
  authentication	<Object>
    Authentication sets credentials for authenticating the requests.

  brokers	<[]string>
    Brokers specifies the list of broker endpoints of a Kafka cluster.
    
    The list represents only the initial set used by the collector's Kafka
    client for the
    first connection only. The collector's Kafka client fetches constantly an
    updated list
    from Kafka. These updates are not reconciled back to the collector
    configuration.
    
    If none provided the target URL from the OutputSpec is used as fallback.

  topic	<string>
    Topic specifies the target topic to send logs to. The value when not
    specified is 'topic'
    
    The Topic can be a combination of static and dynamic values consisting of
    field paths followed by `||` followed by another field path or a static
    value.
    
    A dynamic value is encased in single curly brackets `{}` and MUST end with a
    static fallback value separated with `||`.
    
    Static values can only contain alphanumeric characters along with dashes,
    underscores, dots and forward slashes.
    
    Example:
    
     1. foo-{.bar||"none"}
    
     2. {.foo||.bar||"missing"}
    
     3.
    foo.{.bar.baz||.qux.quux.corge||.grault||"nil"}-waldo.fred{.plugh||"none"}

  tuning	<Object>
    Tuning specs tuning for the output

  url	<string>
    URL to send log records to.
    
    The 'username@password' part of `url` is ignored.
