Each bar is one module, split by the kind of error. Select a module to see only that module in everything on this page; select it again to go back.
Select one to open it in the error list.
These run all the time, so they are kept apart from the errors above. The status comes from how recently a job logged an error, not from whether the job is running.
One bar per hour (or day). Green means the module logged no errors in that hour, amber some, red many. Only modules that logged at least one error in this range are listed, and "quiet" means nothing was logged, not proof that it is running. Select a name to open its errors.
People who switch between Dark and Light themselves keep their own choice.
Applies as soon as that person signs in, and goes back to the style for everyone when they sign out. If users may pick their own style, their own pick still wins.
