mongoqp

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

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

Setup

Installation

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

Configuration

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
• mongodb.client.uri: MongoDB connection URI string
• mongodb.client.uriOptions: MongoDB connection URI options
• mongodb.client.driverOptions: MongoDB driver options
• 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 MongoDB\Client). The connection may be customized via the mongodb.client options, like so:

$app['mongodb.client.uri'] = 'mongodb://example.com:27017';

The above example connects to a standalone server by its hostname. Consult the MongoDB PHP library 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

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