Prerequisites to use

Users should prepare protocol buffers with the following compilers:

Configuration

Note: Protocol Buffer v2 files use .pb.rb extensions whereas Protocol Buffer v3 files use _pb.rb in their filename endings. Please be careful which version is used in your protobuf definitions.

For Protobuf 3

<parse>
  @type protobuf
  class_file /path/to/your/protobuf/class_file_pb.rb
  class_name Your.Protobuf.Class.Name # For protobuf3
  protobuf_version protobuf3
  # suppress_decoding_error false
  # include_paths [/path/to/your/protobuf/class_file_pb.rb, /path/to/your/protobuf/class_file2_pb.rb, ...]
</parse>

Note: Protobuf version 3 requires to use dot for nested class name seperator:

Your::Protobuf::Class::Name class should be in class_name as follows:

class_name Your.Protobuf.Class.Name

For Protobuf 2

<parse>
  @type protobuf
  class_file /path/to/your/protobuf/class_file.pb.rb
  class_name Your::Protobuf::Class::Name # For protobuf2
  protobuf_version protobuf2
  # suppress_decoding_error false
  # include_paths [/path/to/your/protobuf/class_file.pb.rb, /path/to/your/protobuf/class_file2.pb.rb, ...]
</parse>
