James Pretorius updated LOG4J2-541:
-----------------------------------
Description:
Currently the DynamicThresholdFilter only supports key values pairs in the
ThreadContextMap. It would be good to see this expanded to include all log4j2
lookups.
In the below example the threshold level would be stored in a map value
substituted at runtime.
{code:javascript|title=log4j2.json snippet}
"root":{
"AppenderRef":{
"ref":"Console Appender",
"DynamicThresholdFilter":{
"defaultThreshold":"debug",
"key":"$${map:log.console.level}",
"onMatch":"ACCEPT",
"onMisMatch":"DENY",
"keyValuePair":[
{
"key":"off",
"value":"off"
},
{
"key":"fatal",
"value":"fatal"
},
{
"key":"error",
"value":"error"
},
{
"key":"warn",
"value":"warn"
},
{
"key":"info",
"value":"info"
},
{
"key":"debug",
"value":"debug"
},
{
"key":"trace",
"value":"trace"
}
]
}
}
}
{code}
Alternatively, allow the threshold filter to be substituted with a runtime
lookup value.
{code:javascript|title=log4j2.json snippet}
"root":{
"AppenderRef":{
"ref":"Console Appender",
"ThresholdFilter":{
"level":"$${map:log.console.level}",
"onMatch":"ACCEPT",
"onMisMatch":"DENY"
}
}
}
{code}
The above will allow the developer to customise the log level at runtime across
various loggers, appenders etc.
