Configuration for the Fluentd tracer. This tracer extension will send the emitted traces over a TCP connection to an upstream that is accepting the Fluentd Forward Protocol as described in: `Fluentd Forward Protocol Specification <https://github.com/fluent/fluentd/wiki/Forward-Protocol-Specification-v1>`_. [#extension: envoy.tracers.fluentd] [#next-free-field: 7]

• string cluster = 1

  The upstream cluster to connect to for streaming the Fluentd messages.

• string tag = 2

  A tag is a string separated with ``.`` (e.g. ``log.type``) to categorize events. See: https://github.com/fluent/fluentd/wiki/Forward-Protocol-Specification-v1#message-modes

• string stat_prefix = 3

  The prefix to use when emitting tracer stats.

• optional google.protobuf.Duration buffer_flush_interval = 4

  Interval for flushing traces to the TCP stream. Tracer will flush requests every time this interval is elapsed, or when batch size limit is hit, whichever comes first. Defaults to 1 second.

• optional google.protobuf.UInt32Value buffer_size_bytes = 5

  Soft size limit in bytes for access log entries buffer. The logger will buffer requests until this limit it hit, or every time flush interval is elapsed, whichever comes first. When the buffer limit is hit, the logger will immediately flush the buffer contents. Setting it to zero effectively disables the batching. Defaults to 16384.

• optional config.core.v3.RetryPolicy retry_policy = 6

  Optional retry, in case upstream connection has failed. If this field is not set, the default values will be applied.
