c{length}
lo{length}
logger{length} |
Outputs the name of the logger at the origin of the logging event. |
C{length}
class{length} |
Outputs the fully-qualified class name of the caller issuing the logging request. |
contextName
cn |
Outputs the name of the logger context to which the logger at the origin of the event was attached to. |
d{pattern}
date{pattern} |
Used to output the date of the logging event |
| F / file |
Outputs the file name where the logging request was issued. |
| caller{depth} |
Outputs location information of the caller which generated the logging event. |
| L / line |
Outputs the line number from where the logging request was issued. |
| m / msg / message |
Outputs the application-supplied message associated with the logging event. |
| M / method |
Outputs the method name where the logging request was issued. |
| n |
Outputs the platform dependent line separator character or characters. |
| p / le / level |
Outputs the level of the logging event. |
| r / relative |
Outputs the number of milliseconds elapsed since the start of the application. |
| t / thread |
Outputs the name of the thread that generated the logging event. |
X{key:-defaultVal}
mdc{key:-defaultVal} |
Outputs the MDC (mapped diagnostic context) associated with the thread. |
ex{depth}
exception{depth}
throwable{depth} |
Outputs the stack trace of the exception associated with the logging event, if any. |
xEx{depth}
xException{depth}
xThrowable{depth} |
Same as the %throwable conversion word above with the addition of class packaging information. |
nopex
nopexception |
Although it pretends to handle stack trace data, this conversion word does not output any data, thus, effectively ignoring exceptions. |
| marker |
Outputs the marker associated with the logger request. |
| property{key} |
Outputs the value associated with a property named key. |
| replace(p){r, t} |
Replaces occurrences of 'r', a regex, with its replacement 't' in the string produces by the sub-pattern 'p'. |
rEx{depth}
rootException{depth} |
Outputs the stack trace of the exception associated with the logging event, if any. |
