MessagePack

MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON.

Format Definitions

Output of this format is MessagePack binary representation of metrics that have identical structure of the below JSON.

{
   "name":"cpu",
   "time": <TIMESTAMP>, // https://github.com/msgpack/msgpack/blob/master/spec.md#timestamp-extension-type
   "tags":{
      "tag_1":"host01",
      ...
   },
   "fields":{
      "field_1":30,
      "field_2":true,
      "field_3":"field_value"
