Developer Tools - Log Viewer blank window

My production environment, a electricity SPOT optimizing system runs on a Raspi4 on openHABian3 and uses the Frontail logger - everything been running fine for two years.

Now I am setting up a new version of the system using openHABian4 that advises to stay away from the Frontail logger. I have tried to get log output on the new Developer Tools - Log viewer but I cant get any output in the logger window. If I use a separate SSH logfile reader the content of both logfiles are normal.

What am I missing here, haven’t found any useful information googling…

First of all, you can still use frontail to get the logs back. Frontail itself but it still can be used.

@chris Do you have an idea how to analyze why the log viewer may not show anything if the log files are actually healthy?

If no logs have occurred after opening the log viewer no longs will be shown. It’s currently only able to show logs that happen while the viewer is open.

The log viewer is fed by a websocket connection. I believe there are some situations where this websocket can get inturpted so it doesn’t work such as accessing through the cloud server in some circumstances.

Thank you for the explanation - guess I still then have to go with Frontail.
