<!--T:1-->
'''Tracking categories''' are a feature of MediaWiki which allow pages with certain characteristics to be tracked. They work by adding any such page to a category automatically.
</translate>

<translate><!--T:17--> Since <tvar name=1>{{ll|MediaWiki 1.23}}</tvar>, tracking categories are listed in the <tvar name=2>{{ll|Manual:$wgTrackingCategories|$wgTrackingCategories}}</tvar> configuration variable, and can be viewed on <tvar name=3>[[Special:TrackingCategories]]</tvar>.</translate>
<translate><!--T:38--> Since MediaWiki 1.25, tracking categories, which are added by MediaWiki itself, are hard-coded in the MediaWiki source code, and <tvar name=1>{{ll|Manual:$wgTrackingCategories|$wgTrackingCategories}}</tvar> is kept for backwards compatibility.</translate>

<translate>
<!--T:2-->
What category to use is determined by the tracking category's [[<tvar name=1>Special:MyLanguage/Help:System message</tvar>|system message]], that is, a page in MediaWiki namespace. If the message is a single hyphen-minus (-), then the tracking category is disabled. Often wiki admins mark such categories as hidden (using the <tvar name=2><code><nowiki>__HIDDENCAT__</nowiki></code></tvar> [[<tvar name=magic>Special:MyLanguage/Help:Magic words</tvar>|magic word]]), since they are meant for maintenance and not general consumption. Some sites use <tvar name=3>{{ll|Extension:ParserFunctions|Parser functions}}</tvar> to modify which category is used based on namespace, but that doesn't work properly until 1.19.

<!--T:16-->
Some wikis add custom tracking categories via some hacks, for instance [[<tvar name=1>w:it:Categoria:Pagine con errori nelle espressioni</tvar>|this category]], which tracks pages with <tvar name=2><nowiki>#expr</nowiki></tvar> errors, added through the [[<tvar name=3>w:it:Special:PrefixIndex/MediaWiki:Pfunc expr</tvar>|relevant errors]] shown on such pages.

The following tracking categories are added by MediaWiki itself, or have been in the past.
