Tracking categories
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 (43 C, 162 P, 1,049 F) | 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 (1 P) | 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 (empty) | expansion-depth-exceeded-category | The page exceeds the maximum expansion depth. | 
| Pages with too many expensive parser function calls (empty) | expensive-parserfunction-category | The page uses too many expensive parser functions (like #ifexist). See Manual:$wgExpensiveParserFunctionLimit. | 
| Hidden categories (63 C) | 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 (1 P) | 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 (empty) | node-count-exceeded-category | The page exceeds the maximum node count. | 
| Noindexed pages (empty) | 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 (empty) | nonnumeric-formatnum | The page contains a non-numeric argument to the formatnum parser function. | 
| Pages containing omitted template arguments (empty) | post-expand-template-argument-category | The page is bigger than $wgMaxArticleSizeafter expanding a template argument (something in triple braces, like{{{Foo}}}). | 
| Pages where template include size is exceeded (empty) | post-expand-template-inclusion-category | The page size is bigger than $wgMaxArticleSizeafter expanding all the templates, so some templates were not expanded. | 
| Pages with ignored display titles (1 P) | 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 (empty) | 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 (empty) | template-loop-category | The page contains a template loop, ie. a template which calls itself recursively. |
