Log format: Adhere to the OpenTelemetry standard

[ziomill]

Hello,

We are designing the new log format, and we would adhere to the OpenTelemetry standard.

We are trying to map the actual log format:

{
   "tag":"my_log_tag",
   "timestamp_local":"2022-02-04T17:24:19.067+01:00",
   "timestamp_utc":"2022-02-04T16:24:19.067Z",
   "event-id":"abc-def-ghi-123",
   "correlation-id":"1234asdf5678",
   "session-id":"session_000",
   "solution-user":"MyFrontend",
   "user-id":"ab126575",
   "version":"1.0.0",
   "domain":"Pltfrm",
   "module_id":"MyMicroservice",
   "container":"my-container-13f34",
   "level":"INFO",
   "thread":"main",
   "class":"com.my.company.MyClass",
   "message":"This is my INFO message"
}

with the OpenTelemetry one:

{
   "Timestamp":"2022-02-04T16:24:19.067Z",   	 // Map to "timestamp_utc"
   "TraceId":"f4dbb3edd765f620",   	         // Map to "correlation-id"
   "SpanId":"43222c2d51a7abe3",   	         // New
   "SeverityText":"INFO",			 // Map to "level"
   "Body":"This is my INFO message"          	 // Map to "message"
    // Infrastructure related fields	
    "Resource": {							 	 	
		"container-name":"my-container-13f34",	 	// Map to "container"
		"container-version":"1.0.0",			// Map to "version"
   },
   // Other Custom fields	
   "Attributes": {									
		"tag":"my_log_tag",	
		"timestamp_local":"2022-02-04T17:24:19.067+01:00",
		"domain":"Pltfrm",
		"module-id":"MyMicroservice"
		"session-id":"session_000",
		"event-id":"abc-def-ghi-123",
		"solution-user":"MyFrontend",
		"user-id":"ab126575",
		"thread":"main",
		"class":"com.my.company.MyClass"
   }
}

is this mapping correct?

Thank you

hi @ziomill, this sounds like a better question for the specification repo, or if it helps you can check out the mapping we've done in this repo for log4j and logback

hi @trask,

You're right.
The right place for this question is the specification repo.

Thank you
