Hello everyone,
i am trying to configure a java webapp which is using log4j2, that it logs
against graylog2.
This is my log4j2.xml:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn">
<Appenders>
<GELF name="gelfAppender" server="localhost" port="12201"
hostName="appserver" ignoreExceptions="false"/>
</Appenders>
<Loggers>
<Root level="warn">
<AppenderRef ref="gelfAppender"/>
</Root>
</Loggers>
</Configuration>
I have added the corresponding java libraries (log4j-api, log4j-core,
log4j2-gelf, log4j-nosql and their dependencies) to the classpath.
Further i installed the graylog2 infrastructure on my system using the
quickstart installer which seems to have worked correctly.
Then i added an input of type "GELF TCP" with following configuration
options:
port: 12201
bind_address: 0.0.0.0
recv_buffer_size: 1048576
When i now start my system, i get the following exception
org.apache.logging.log4j.core.appender.AppenderLoggingException: Attempted
to append to non-started appender gelfAppender

I can't find the error in there and would be glad someone of you can figure
out
Best Regards
Christian
