Doesn't work in extensions??

- Do you have a
use MediaWiki\Logger\LoggerFactory;at the top of the file? Legoktm (talk) 21:09, 17 September 2016 (UTC) - Thanks, that fixed it. Subfader (talk) 21:12, 18 September 2016 (UTC)
Use one of the core logging channels?

In order to instantiate a LoggerFactory instance (when NOT coding for an extension), the manual says to "use one of the core logging channels". Is this supposed to be defined or standardized somewhere like Manual:$wgLogTypes is? Because when I search core, there are dozens of different "channels" and there doesn't seem to be any rhyme or reason to them. The manual might as well say "use any string".

- Yes, it really is basically "use any string that is configured to record debug log events to a file in your local MediaWiki deployment". There is no central codified list of widely used log channels.
- For a deployment where
$wgDebugLogFilelogging is being used it really does not matter. For a deployment like the Wikimedia production cluster where individual log channels are selectively enabled then the choice does make a difference. When converting a wfDebugLog() call, use the same channel name. When converting a wfDebug() call, use your best judgement for selecting an existing channel or creating a new channel using an arbitrary string. BDavis (WMF) (talk) 15:55, 8 March 2018 (UTC)
