mongoqp is a frontend for MongoDB's query profiler collections (i.e. db.system.profile), built using Silex and PHP 5.4.

It currently supports:

  • Toggling query profiler levels (off, slow, all) per database
  • Grouping similar queries by BSON structure
  • Reporting aggregate query statistics (min, max, average, times)
  • Sorting, pagination and filtering via DataTables

Future plans:

  • Control over slow query thresholds
  • Improving analytics
  • Persistent data collection
  • Integration with Justin Hileman's Genghis (single-file MongoDB admin)
  • Integration with Tyler Brock's mongo-hacker (MongoDB shell enhancements)


Server view

Database view



Dependencies are managed with Composer, a PHP package manager. This project is also published as a package, which means it can be installed with:

$ composer create-project jmikola/mongoqp


The src/ directory includes a config.php.dist file, which may be copied to config.php and customized. If config.php is not present, the default configuration will be included.

Currently, the following options are available:

  • debug: Enable verbose error reporting
  • twig.cache_dir: Cache directory for Twig templates
Database Connection

By default, the application will connect to a standalone MongoDB server on the local host (i.e. new MongoClient()). The connection may be customized by defining a shared mongo service in config.php:

$app['mongo'] = $app->share(function() {
    return new \MongoClient('mongodb://');

The above example connects to a standalone server by its hostname. Consult the PHP driver's connection documentation for additional examples on connecting to a replica set or specifying auth credentials.

Database profiling cannot be enabled on mongos instances. If you are profiling queries in a sharded cluster, the application should be configured to connect to an individual shard.

Cache Directory

By default, the application will use mongoqp-cache/ within the system's temporary directory. This path, which must be writable, may be customized via the twig.cache_dir configuration option.

Web Server

The application can be started using:

$ php -S localhost:8080 -t web web/index.php

Instructions for other web server configurations are outlined in the Silex documentation.
