Query Monitor – verktygspanelen för utvecklare av WordPress


Query Monitor är panelen för utvecklarverktyg för WordPress. Den möjliggör felsökning av databasfrågor, PHP-fel, åtgärds-hookar och åtgärder, block i blockredigeraren, köade skript och stilmallar, HTTP API-anrop och mycket mer.

Det innehåller några avancerade funktioner som felsökning av Ajax-anrop, REST API-anrop, kontroller av användarbehörigheter och fullt stöd för blockteman och ”Redigering av hela webbplatsen” (FSE). Det inkluderar möjligheten att begränsa mycket av dess utdata efter tillägg eller tema, så att du snabbt kan hitta dåligt presterande tillägg, teman eller funktioner.

Query Monitor focuses heavily on presenting its information in a useful manner, for example by showing aggregate database queries grouped by the plugins, themes, or functions that are responsible for them. It adds an admin toolbar menu showing an overview of the current page, with complete debugging information shown in panels once you select a menu item.

Query Monitor stöder versioner av WordPress som är upp till tre år gamla och PHP version 7.4 eller senare.

For complete information, please see the Query Monitor website.

Här är en översikt över vad som visas för varje sidladdning:

  • Database queries, including notifications for slow, duplicate, or erroneous queries. Allows filtering by query type (SELECT, UPDATE, DELETE, etc), responsible component (plugin, theme, WordPress core), and calling function, and provides separate aggregate views for each.
  • The template filename, the complete template hierarchy, and names of all template parts that were loaded or not loaded (for block themes and classic themes).
  • PHP errors presented nicely along with their responsible component and call stack, and a visible warning in the admin toolbar.
  • Användning av ”Doing it Wrong” eller ”Deprecated”-funktionalitet i koden på din webbplats.
  • Blocks and associated properties within post content and within full site editing (FSE).
  • Matched rewrite rules, associated query strings, and query vars.
  • Enqueued scripts and stylesheets, along with their dependencies, dependents, and alerts for broken dependencies.
  • Language settings and loaded translation files (MO files and JSON files) for each text domain.
  • HTTP API requests, with response code, responsible component, and time taken, with alerts for failed or erroneous requests.
  • User capability checks, along with the result and any parameters passed to the capability check.
  • Environment information, including detailed information about PHP, the database, WordPress, and the web server.
  • The values of all WordPress conditional functions such as is_single(), is_home(), etc.
  • Transienter som uppdaterades.
  • Användning av switch_to_blog() och restore_current_blog() på nätverksinstallationer av WordPress.


  • Whenever a redirect occurs, Query Monitor adds an HTTP header containing the call stack, so you can use your favourite HTTP inspector or browser developer tools to trace what triggered the redirect.
  • The response from any jQuery-initiated Ajax request on the page will contain various debugging information in its headers. PHP errors also get output to the browser’s developer console.
  • The response from an authenticated WordPress REST API request will contain an overview of performance information and PHP errors in its headers, as long as the authenticated user has permission to view Query Monitor’s output. An an enveloped REST API request will include even more debugging information in the qm property of the response.

By default, Query Monitor’s output is only shown to Administrators on single-site installations, and Super Admins on Multisite installations.

In addition to this, you can set an authentication cookie which allows you to view Query Monitor output when you’re not logged in (or if you’re logged in as a non-Administrator). See the Settings panel for details.

Query Monitor is private by default and always will be. It does not persistently store any of the data that it collects. It does not send data to any third party, nor does it include any third party resources. Query Monitor’s full privacy statement can be found here.


Query Monitor aims to be fully accessible to all of its users. Query Monitor’s full accessibility statement can be found here.

Vanliga frågor

Fungerar detta tillägg med PHP 8?

Ja, det är aktivt testat och fungerar upp till PHP 8.2.

Vem kan se Query Monitors utdata?

By default, Query Monitor’s output is only shown to Administrators on single-site installations, and Super Admins on Multisite installations.

In addition to this, you can set an authentication cookie which allows you to view Query Monitor output when you’re not logged in, or when you’re logged in as a user who cannot usually see Query Monitor’s output. See the Settings panel for details.

Does Query Monitor itself impact the page generation time or memory usage?

Kort svar: Ja, men bara lite grann.

Long answer: Query Monitor has a small impact on page generation time because it hooks into a few places in WordPress in the same way that other plugins do. The impact is negligible.

On pages that have an especially high number of database queries (in the hundreds), Query Monitor currently uses more memory than I would like it to. This is due to the amount of data that is captured in the stack trace for each query. I have been and will be working to continually reduce this.

Can I prevent Query Monitor from collecting data during long-running requests?

Yes, you can call do_action( 'qm/cease' ) to instruct Query Monitor to cease operating for the remainder of the page generation. It will detach itself from further data collection, discard any data it’s collected so far, and skip the output of its information.

This is useful for long-running operations that perform a very high number of database queries, consume a lot of memory, or otherwise are of no concern to Query Monitor, for example:

  • Backing up or restoring your site
  • Import eller export av en stor mängd data
  • Körning av säkerhetsgenomsökningar

Finns det några utökningstillägg för Query Monitor?

A list of add-on plugins for Query Monitor can be found here.

In addition, Query Monitor transparently supports add-ons for the Debug Bar plugin. If you have any Debug Bar add-ons installed, deactivate Debug Bar and the add-ons will show up in Query Monitor’s menu.

Var kan jag föreslå en ny funktion eller rapportera ett fel?

Please use the issue tracker on Query Monitor’s GitHub repo as it’s easier to keep track of issues there, rather than on the wordpress.org support forums.

Är Query Monitor tillgänglig på Altis?

Yes, the Altis Developer Tools are built on top of Query Monitor.

Is Query Monitor available on WordPress VIP?

Ja, men en användare måste beviljas view_query_monitor-behörighet för att se Query Monitor även om de är administratörer. Se WordPress VIP-dokumentation för mer information.

I’m using multiple instances of `wpdb`. How do I get my additional instances to show up in Query Monitor?

Denna funktion togs bort i version 3.12 eftersom den sällan användes och avsevärt ökade underhållsbördan för Query Monitor självt. Fortsätt gärna att använda version 3.11 om du behöver använda denna funktion.

Can I click on stack traces to open the file in my editor?

Ja, du kan aktivera detta i panelen Inställningar.

Hur kan jag rapportera ett säkerhetsproblem?

You can report security bugs through the Patchstack Vulnerability Disclosure Program. The Patchstack team helps validate, triage, and handle any security vulnerabilities. Report a security vulnerability here.

Tar du emot donationer?

Jag tar emot sponsring via ”GitHub Sponsors”-programmet. Om du arbetar på en byrå som utvecklar med WordPress, be ditt företag att ge sponsring för att investera i sin leveranskedja. De verktyg som jag underhåller sparar förmodligen tid och pengar för ditt företag, och GitHub-sponsring kan nu göras på organisationsnivå.

In addition, if you like the plugin then I’d love for you to leave a review. Tell all your friends about it too!
