Could be a problem on my end, but Installing this version with Wildfly does not let me access the configuration->logging web console page. It comes up blank. I use this to change the command logging level on a running server.
Seems to happen in version 13, also.
I tried using the checkboxes in subsystem>teiid>configure>logging but they did not seem to change the level.
Please let me know if this if reproducible for you.
