-------------------------------------
Summary: Allow Json based layouts to output a root element
Key: LOG4J2-2985
URL: https://issues.apache.org/jira/browse/LOG4J2-2985
Project: Log4j 2
Issue Type: Improvement
Components: Layouts
Reporter: Ron Grabowski
This request applies to all all Json layouts:
* https://github.com/apache/logging-log4j2/tree/master/log4j-layout-jackson-json
* https://github.com/apache/logging-log4j2/tree/master/log4j-layout-jackson
*
https://github.com/apache/logging-log4j2/tree/master/log4j-layout-template-json
----
The layouts in this folder:
[https://github.com/apache/logging-log4j2/tree/master/log4j-layout-template-json/src/main/resources]
Output a structure that looks like this:
{code}
{
"instant": {
},
"thread": {
},
"level": {
},
"loggerName": {
}
{code}
Add a set of new templates and/or a config value to set a root element. Default
could be "logEvent" but could be overridden to something else like "data":
{code}
{
"data": {
"instant": {
},
"thread": {
},
"level": {
},
"loggerName": {
}
{code}
A root element (sometimes?) makes it easier to extract data in 3rd party tools
like Splunk's _spath_ command:
https://docs.splunk.com/Documentation/Splunk/latest/SearchReference/Spath
Maybe its as simple as calling _withRootName_?
https://stackoverflow.com/questions/15936680/how-to-rename-root-key-in-json-serialization-with-jackson
{code}
final ObjectWriter writer = mapper.writer().withRootName("rootName");
{code}
