Never mind, dumb comment. My bad

Some changes to the GELF messaging are coming in GL v 0.9.6:
Graylog2/graylog2-server@57b3daa

Make sure the appender works with that.

Hi

I have a situation where i need to log few values and put them into additional fields. What are the steps required to add additional fields to the graylog?

will the following steps work:

1. Get GELF appender from log4j logger.
2. create a map and set additionalFields in GELF Appender with this map.

Note: The Java class from where i want to add the additional fields is not the is not the initiation point of my application.

Looking for the quick response from your end!

Regards,
Gaurav

I have been trying to use your appender to log session data to my graylog instance from a tomcat application. However I continue to get the following error.

groovy.lang.MissingMethodException: No signature of method: org.apache.log4j.spi.LoggingEvent.getTimeStamp() is applicable for argument types: () values: []

I noticed this project is stale and there is a newer version at is maintained at https://github.com/realityforge/gelf4j. It's also confusing because this project doesn't show as a fork to https://github.com/realityforge/gelf4j or vice versa.

For some reason the stack traces are not showing up in the GELF messages.
Have to investigate what the issue is and fix for next release.
