No, thats not what bugs me. I understand that.
I am fighting with this log4j2.json configuration and can't find the
error. Its only outputting the error messages. A similar log4j2.xml
file works as expected, it is just the json file. If you can explain
me my error, I would be glad.
{
"configuration": {
"status": "trace"
},
"appenders": {
"appender": [
{
"type": "Console",
"name": "Console",
"PatternLayout": {
"pattern": "%m%n"
}
}
]},
"loggers": {
"logger": [
{
"name": "Sub",
"level": "TRACE",
"appender-ref": {
"ref": "Console"
}
}
],
"root": {
"level": "error",
"appender-ref": {
"ref": "Console"
}
}
}
}
