This is equivalent to sending all logs to the console, with default go log being sent to the console log too.
## Releasing-and-Reopening, Pausing and Resuming logging
If you are running on Unix you may wish to release-and-reopen logs in order to use `logrotate` or other tools.
It is possible force gitea to release and reopen it's logging files and connections by sending `SIGUSR1` to the
running process, or running `gitea manager logging release-and-reopen`.
Alternatively, you may wish to pause and resume logging - this can be accomplished through the use of the
`gitea manager logging pause` and `gitea manager logging resume` commands. Please note that whilst logging
is paused log events below INFO level will not be stored and only a limited number of events will be stored.
Logging may block, albeit temporarily, slowing gitea considerably whilst paused - therefore it is
recommended that pausing only done for a very short period of time.
## Adding and removing logging whilst Gitea is running
It is possible to add and remove logging whilst Gitea is running using the `gitea manager logging add` and `remove` subcommands.
This functionality can only adjust running log systems and cannot be used to start the access, macaron or router loggers if they
were not already initialised. If you wish to start these systems you are advised to adjust the app.ini and (gracefully) restart
the Gitea service.
The main intention of these commands is to easily add a temporary logger to investigate problems on running systems where a restart
may cause the issue to disappear.
## Log colorization
Logs to the console will be colorized by default when not running on
