# MessagePack
|
||
|
|
|
||
|
|
[MessagePack](https://msgpack.org) 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.
|
||
|
|
|
||
|
|
```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"
|
||
|
|
"field_4":30.1
|
||
|
|
...
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
MessagePack has it's own timestamp representation. You can find additional information from [MessagePack specification](https://github.com/msgpack/msgpack/blob/master/spec.md#timestamp-extension-type).
