Centralized Logging of openhab via Graylog, Elasticsearch etc

Apps & Services 3rd Party
#1

The out-of-the box logging handing of openhabian via frontail works perfectly - if the log entries are only a couple of minutes / hours old. As I was looking for a centralized logging solution to be able to easily find log entries that are a couple of days / weeks old without filling up my openhabian setup, I came to this tutorial which works quite fine Logging to graylog and relies on docker containers for elastic search, redis and graylog as centralized logging handler - all for free.

The solution works fine but as i implemented the log appender via log4j (via syslog - udp) every time I reboot the (seperate) logging instance of graylog the connection breaks up (which should not happen when using UDP should it). I have to reboot openhab2 too to make it work again - which is not a good productive setup.

Anyone able to help?

This phrase appears to be entirely content free.

#4

Means I receive no more UDP connections from the openhabian system to my graylog instance - thought that is clear. I have no clue where to look up to receive more content.

#5

It the packets are being sent but not received the issue appears to be on the graylog side or the internal Docker networking between the applications then.
