This page lists tracking categories which are automatically populated by the MediaWiki software. Their names can be changed by altering the relevant system messages in the MediaWiki namespace.
| Tracking category | Message name | Category inclusion criteria |
|---|---|---|
| Pages with broken file links | broken-file-category | The page contains a broken file link (a link to embed a file when the file does not exist). |
| Pages using duplicate arguments in template calls | duplicate-args-category | The page contains template calls that use duplicates of arguments, such as {{foo|bar=1|bar=2}} or {{foo|bar|1=baz}}. |
| Pages where expansion depth is exceeded | expansion-depth-exceeded-category | The page exceeds the maximum expansion depth. |
| Pages with too many expensive parser function calls | expensive-parserfunction-category | The page uses too many expensive parser functions (like #ifexist). See Manual:$wgExpensiveParserFunctionLimit. |
| Hidden categories | hidden-category-category | The category contains __HIDDENCAT__ in its page content, which prevents it from showing up in the category links box on pages by default. |
| Indexed pages | index-category | The page has a __INDEX__ on it (and is in a namespace where that flag is allowed), and hence is indexed by robots where it normally wouldn't be. |
| Pages where node count is exceeded | node-count-exceeded-category | The page exceeds the maximum node count. |
| Noindexed pages | noindex-category | The page is not indexed by robots because it has the magic word __NOINDEX__ on it and is in a namespace where that flag is allowed. |
| Pages with non-numeric formatnum arguments | nonnumeric-formatnum | The page contains a non-numeric argument to the formatnum parser function. |
| Pages containing omitted template arguments | post-expand-template-argument-category | The page is bigger than $wgMaxArticleSize after expanding a template argument (something in triple braces, like {{{Foo}}}). |
| Pages where template include size is exceeded | post-expand-template-inclusion-category | The page size is bigger than $wgMaxArticleSize after expanding all the templates, so some templates were not expanded. |
| Pages with ignored display titles | restricted-displaytitle-ignored | The page has an ignored {{DISPLAYTITLE}} because it is not equivalent to the page's actual title. |
| Pages which use = as a template | template-equals-category | The page contains {{=}} but on this wiki that does not expand to =. This usage is deprecated; a future MediaWiki version will implement {{=}} as a parser function. |
| Pages with template loops | template-loop-category | The page contains a template loop, ie. a template which calls itself recursively. |
| Pages where the unstrip depth limit is exceeded | unstrip-depth-category | The page exceeds the unstrip depth limit. |
| Pages where the unstrip size limit is exceeded | unstrip-size-category | The page exceeds the unstrip size limit. |
| Pages with short description | shortdescription-category | No description available. |
| Pages with RSS feeds | rss-tracking-category | The page has an RSS feed. |
