Slow Query Logger for Laravel

Installation/Quickstart

composer require consilience/laravel-slow-query-logger

or add the following line to composer.json then run composer update:

"require": {
    "consilience/laravel-slow-query-logger": "^2.0"
}

Turn on slow query logging:

LARAVEL_SLOW_QUERY_LOGGER_ENABLED=true

Look into your log file to see your slow queries.

Configuration

The configuration file can be published with the following command:

php artisan vendor:publish --provider="Consilience\Laravel\SlowQueryLogger\SlowQueryLoggerProvider"

You will likely not need to publish the config; just set required environment variables as listed below.

enabled

Enable the slow queries logger.

You can set this value through environment variable LARAVEL_SLOW_QUERY_LOGGER_ENABLED. It is false by default.

channel

Sets the channel to log in. This can be handy if you want to keep all query logs separate from other log messages.

You can set this value through environment variable LARAVEL_SLOW_QUERY_LOGGER_CHANNEL. By default, the application default logging channel will be used.

level

Set the log-level for logging the slow queries.

You can set this value through environment variable LARAVEL_SLOW_QUERY_LOGGER_LEVEL. It is debug by default.

threshold-ms

Only log queries that take longer than this number of milliseconds to complete.

You can set this value through environment variable LARAVEL_SLOW_QUERY_LOGGER_THRESHOLD_MS. It is 700 by default. A value of 0 will log all queries.

Usage

By default, bind variables are not included in the logged details. Just the core query is logged:

[20[2022-08-02 22:15:33] production.DEBUG: SQL 6663.970 mS: update users set name = ?, users.updated_at = ? where id = ?

By setting LARAVEL_SLOW_QUERY_LOGGER_REPLACE_BINDINGS=true the query will have its bind variables substituted with the matching values:

[2022-08-02 16:17:13] production.DEBUG: SQL 784.200 mS: update users set name = 'JJ', users.updated_at = '2022-08-02 16:17:05' where id = '1'

You can also (or alternatively) list the bind data separately in the context of the log by setting LARAVEL_SLOW_QUERY_LOGGER_SHOW_BINDINGS=true. This may be useful to observe the data types in more detail, since substituting the bindings will treat all values as strings.

[2022-08-02 22:22:35] production.DEBUG: SQL 413.910 mS: update users set name = 'JJ', users.updated_at = '2022-08-02 22:21:50' where id = '1' {"bindings":["JJ","2022-08-02 22:21:50",1]}
