Fuseki log files

[Uldis Bojars]

Hi!

After installing Fuseki according to the Skosmos installation instructions [1] is there anything else that you need to do in order to enable logging to the /var/log/fuseki directory?

I've created /var/log/fuseki directory as instructed but it stays empty. Fuseki log messages appear in syslog instead.

Hi Uldis!

You probably need to set up Fuseki logging using a log4j configuration
file. It's explained here:
https://jena.apache.org/documentation/fuseki2/fuseki-logging.html

I've included below a configuration file (log4j2.properties) for one of
our Fuseki installations that you can perhaps use as a starting point.
It sets up logging under /var/log/fuseki .

If you have a suggestion for how to fix this in the tutorial
installation with minimal effort, I'd be thankful ;)

Hope this helps,
Osma

Hi!

This is an old thread but I thought I'd share information about Fuseki logging in a Skosmos installation.

There are 2 different "log4j2.properties" files for Fuseki - one in /etc/fuseki and another in /opt/fuseki.

Turns out I was editing the wrong file (the one in /etc/fuseki) while the correct file was in /opt/fuseki.

If you edit the correct file, its changes get applied to Fuseki and you can make it log to a file, etc.

Best regards,

Uldis
