You can probably figure it out just by looking at your existing log4j2.xml file. But if not see Log4j – Configuring Log4j 2.
Note, other options for centralized logging with openHAB:
- Logging to graylog
- Fluentd (I don’t see any tutorials for using OH with this one yet)
- Using loki+promtail+grafana for Openhab system and log monitoring
There are of course others.
ELKI stack is pretty heavy weight and Elasticsearch just by itself is going to consume a lot of resources. I don’t know about these other approaches.
