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 |
|---|---|---|
| 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. |
| 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 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 with too many expensive parser function calls | expensive-parserfunction-category | The page uses too many expensive parser functions (like #ifexist). See Manual:$wgExpensiveParserFunctionLimit. |
| 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. |
| Hidden classes (= 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. |
| 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 where node count is exceeded | node-count-exceeded-category | The page exceeds the maximum node count. |
| Pages where expansion depth is exceeded | expansion-depth-exceeded-category | The page exceeds the maximum expansion depth. |
| Pages with syntax highlighting errors | syntaxhighlight-error-category | There was an error when attempting to highlight code included on the page. |
| Files with no machine-readable license | commonsmetadata-trackingcategory-no-license | The file does not have any machine-readable license template. |
| Files with no machine-readable description | commonsmetadata-trackingcategory-no-description | The file does not have a machine-readable information template, or its description field is not filled out. |
| Files with no machine-readable author | commonsmetadata-trackingcategory-no-author | The file does not have a machine-readable information template, or its author field is not filled out. |
| Files with no machine-readable source | commonsmetadata-trackingcategory-no-source | The file does not have a machine-readable information template, or its source field is not filled out. |
