 |serviceName      |String |       |Sets the `service.name` field so you can filter your logs by a particular service |
-|topLevelLabels   |String |`trace.id, transaction.id, span.id, error.id, service.name`|Usually, MDC keys are nested under `labels`[https://www.elastic.co/guide/en/ecs/current/ecs-base.html]. You can specify a comma-separated list of properties which should be on the top level. |
-|includeMarkers   |boolean|`false`|Log [Markers](https://logging.apache.org/log4j/2.0/manual/markers.html) as `tags` |
-|stackTraceAsArray|boolean|`false`|Serializes the `error.stack_trace` as a JSON array where each element is in a new line to improve readability. Note that this requires a slightly more complex [Filebeat configuration](../README.md#when-stacktraceasarray-is-enabled).|
-|includeOrigin    |boolean|`false`|If `true`, adds the `log.origin.file`, `log.origin.function` and `log.origin.line` fields. Note that you also have to set `includeLocation="true"` on your loggers and appenders if you are using the async ones. |
