Hi, You could easyly write your own discriminator class combining
JNDIBasedContextDiscriminator and MDCBasedDiscriminator. Here is an example:
public class CombinedDiscriminator extends ContextAwareBase implements Discriminator<ILoggingEvent> {
private String defaultMDCVal = "default";
public String getDiscriminatingValue(ILoggingEvent event) { String mdcValue = defaultMDCVal; Map<String, String> mdcMap = event.getMdc(); if (mdcMap != null) { mdcValue = mdcMap.get(key); } String contextName = event.getLoggerContextVO().getName(); return contextName + mdcValue; } ..etc }
Thanks for reply, i started to implement, but i noticed that maybe i don't explain well, i dont need "sumValue = contextName + mdcValue" value to use in <FileNamePattern>${newValue}.log</FileNamePattern> That i really need is two values... contextName and mdcValue... The aprox, maybe something like <FileNamePattern>${newValue.substring(0,x)}/${newValue.substring(x,n)}.log</FileNamePattern> or something like <appender ... class="ch.qos.logback.classic.sift.SiftingAppender"> <discriminator class="ch.qos.logback.classic.sift.JNDIBasedContextDiscriminator"> ... <sift> <appender ... class="ch.qos.logback.classic.sift.SiftingAppender"> <discriminator> ... <sift> <appender class="ch.qos.logback.core.rolling.RollingFileAppender"> SiftingAppender inside SiftingAppender to use MDC and contextName. Any suggestion?
