Logs every HTTP request to the website with response details sent to the standard logger, including responses returned directly from cache. It acts as an Apache/Nginx access.log, but stores more useful metadata about the request (timestamp in milliseconds, separate path, query string, headers, attributes) and the response (response generation duration in milliseconds, size, memory usage, cache hit/miss, headers, etc).
This data is useful for monitoring site performance, tracking cache hit rates, and building other analytics reports.
For debugging, you can temporarily enable logging of full HTTP headers and add other custom fields.
Just install the module and it works out of the box, adding a new log entry for each request to the website.
On the settings page /admin/config/development/request_logger (Home » Administration » Configuration »
Development » Request Logger) you can choose exactly which data to store in the logs.
By default, this module works well with the default Drupal loggers (DBLog and Syslog) and stores basic request and response details in the log message string.
To store more details about the request and response, install the Logger module — it will extend log entries with structured data, allowing you to build custom reports and charts by any custom field from the log entry (for example, average response time or memory usage per request, or regexp matches).
The Logger DB module provides viewing logs directly in the Drupal Admin Panel with the ability to aggregate, filter and sort logs by any custom field (eg, sort requests by duration or memory usage), and to build metrics, reports, and charts.
A submodule "Request Logger Reports" provides displaying logged requests and responses directly in the Drupal Admin Panel with the ability to filter by any custom field using the Logger DB module, and even build useful charts with the help of the Charts module.
