not support logging
experimental, it's your responsibility to make sure the reported log data
contains the following attributes, otherwise
SkyWalking is not able to consume them:
-- `service.name`: the name of the service that generates the log data,
OpenTelemetry Java SDK (experimental) has this
- attribute set, if you're using other SDK or agent, please check the
corresponding doc.
+- `service.name`: the name of the service that generates the log data.
+
+And several attributes are optional as add-on information for the logs before
analyzing.
+- `service.layer`: the layer of the service that generates the logs. The
default value is `GENERAL` layer, which is 100% sampled defined by [LAL general
rule](https://github.com/apache/skywalking/blob/master/oap-server/server-starter/src/main/resources/lal/default.yaml)
+- `service.instance`: the instance name that generates the logs. The default
value is empty.
+
+Note, that these attributes should be set manually through OpenTelemetry SDK
or through [attribute#insert in OpenTelemetry
Collector](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/processor/attributesprocessor/README.md).
