requestLog is not being sent

[madmuffin1]

Hi,

I am trying to also send the requestLog to our graylog server. Unfortunately, it does not work (messages are dropped silently). The instance is created correctly but messages cause a NPE in LogbackLogEvent.getCalleeStackTraceElement:74 since the callerDataArray in LogbackLogEvent.loggingEvent.getCallerData() is null.

My entries in the config section:

server:
  type: default # must be set, otherwise requestLog cannot be configured
  requestLog:
    appenders:
      - type: console
      - type: gelf
        host: udp:my.graylog.host
        port: 12201
        additionalFields:
          environment: ${ENVIRONMENT}
          type: access

Versions: Dropwizard 0.9.2, Dropwizard-GELF 0.9.2-4

Hi,

I can confirm that there is a NPE in that case. Note that it's not because callerData is null, but rather due to loggerContext being null. I'm unsure yet whose fault that is.

Note that dropwizard-gelf comes with its own request logger (GelfLoggingFilter). To use it, add the following lines to your App#run() method:

environment.servlets()
    .addFilter("request-logs", new GelfLoggingFilter())
    .addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), true, "/*");

Debugging trying to figure out why my http requests aren't showing up in my logging server I found that the ch.qos.logback.core.AppenderBase is throwing a ClassCastException.

java.lang.ClassCastException: ch.qos.logback.access.spi.AccessEvent cannot be cast to ch.qos.logback.classic.spi.ILoggingEvent
	at biz.paluch.logging.gelf.logback.GelfLogbackAppender.append(GelfLogbackAppender.java:71)
	at ch.qos.logback.core.AppenderBase.doAppend(AppenderBase.java:82)
	at ch.qos.logback.core.spi.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:48)
	at ch.qos.logback.core.AsyncAppenderBase$Worker.run(AsyncAppenderBase.java:265)

So it appears that thad the RequestLog is sending an AccessEvent but the underlying logging structure can't handle that.
