| === Logging changes | ||

||
| [float] | ||
| ==== New JSON format log files in `log` directory | ||
|
|
||
| Elasticsearch now will produce additional log files in JSON format. They will be stored in `*.json` suffix files. | ||
| Following files should be expected now in log directory: | ||
| * ${cluster_name}_server.json | ||
| * ${cluster_name}_deprecation.json | ||
| * ${cluster_name}_index_search_slowlog.json | ||
| * ${cluster_name}_index_indexing_slowlog.json | ||
| * ${cluster_name}.log | ||
| * ${cluster_name}_deprecation.log | ||
| * ${cluster_name}_index_search_slowlog.log | ||
| * ${cluster_name}_index_indexing_slowlog.log | ||
| * ${cluster_name}_audit.json | ||
| * gc.log | ||
|
|
||
| Note: You can configure which of these files are written by editing `log4j2.properties`. | ||
|
|
||
| [float] | ||
| ==== Log files ending with `*.log` deprecated | ||
| Log files with the `.log` file extension using the old pattern layout format | ||
| are now considered deprecated and the newly added JSON log file format with | ||
| the .json file extension should be used instead. | ||
|
There was a problem hiding this comment. nit: formatting: .json should be enclosed in backticks. |
||
| Note: GC logs which are written to the file gc.log will not be changed. | ||

| ==== Docker output in JSON format | ||
|
|
||
| All Docker console logs are now in JSON format. You can distinguish logs streams with the `type` field. | ||

I'd say it is ok that we keep the old format as is but now the new format contains different information (e.g. the cluster UUID is only present in the JSON format).
