Robert Munteanu commented on SLING-9780:
----------------------------------------
Here's what I found so far
- the webconsole page makes a {{POST}} call to the {{LogServlet}} to retrieve
the logging data
- the {{LogServlet}} renders the data (
https://github.com/apache/felix-dev/blob/b91688862f39bf89c87e019ccf81653bb7ec12a1/webconsole/src/main/java/org/apache/felix/webconsole/internal/compendium/LogServlet.java#L85-L118
) based on the {{org.osgi.service.log.LogReaderService}} service
- this service is not deployed in the Sling Starter ( checked
http://localhost:8080/system/console/services )
- we do deploy the {{org.osgi.service.log}} bundle, which exports the
{{org.osgi.service.log}} package, but apparently no services
[~cziegeler] - I know you did some work around the logging bundles for Sling,
maybe you can point me where should I investigate next?

> Key: SLING-9780
> URL: https://issues.apache.org/jira/browse/SLING-9780
> Project: Sling
> Issue Type: Bug
> Components: Starter
> Affects Versions: Starter 12
> Environment: Java 11 and 13 on MacOS
> Reporter: Hans-Peter Stoerr
> Priority: Minor
> Fix For: Starter 12

> In the current Sling Starter 12 snapshot the OSGI Log Service does not work
> properly. This has the effect that in the console at OSGI / Log Service
> [http://localhost:8080/system/console/logs] there is only the display "Log
> Service is not installed/running." and messages from OSGI (such as errors in
> activation methods) are inconveniently logged to stdout instead of the
> configured logfiles like error.log, which gave me some headache until I
> noticed that. :) Both the console plugin and the logging to error.log do
> work properly in version 11.
> This is in spite of the bundle org.apache.sling.commons.logservice being
> active. I tried downgrading it from the currently included 1.1.0 to 1.0.6,
> which works in the version 11 of the Sling Starter, but this doesn't help. So
> I guess it's some kind of configuration problem.
> Thanks so much for your amazing work!
