log to graylog2 by adding external jar to classpath

[#1]

Hi,

in order to log errors and stacktraces to Graylog2 I had the following intention

- manually put the https://github.com/Moocar/logback-gelf as a jar into the nifi dir

- add the jar to the classpath

- change the logback config and add the gelf-appender.

Now, nifi.sh is only loading the bootstrap process that runs nifi. So adding the jar to the cp there is no help. Any idea how I can achieve the effect without touching the nifi source and compile myself?

Thanks for the help!

This works actually, by placing the .jar file into the lib and the lib/bootstrap folder and then just applying the changes to the logback.xml like usually.

<appender name="GELF" class="de.siegmar.logbackgelf.GelfUdpAppender">
  <graylogHost>ip</graylogHost>
  <graylogPort>12201</graylogPort>
</appender>

I am using de.siegmar:logback-gelf/1.0.3.

Issue resolved for me.
