Drupal request log

The Drupal request log (drupal-requests.log) contains a list of requests that Apache has sent to Drupal for processing and display.

For a list of the log files handled by Cloud Platform, including accessing these log files, log file retention, and their locations, see About Cloud Platform logging. You can also review information about how to streaming Apache log entries in real time from your browser.

Note for log forwarding users

Acquia’s log forwarding feature prepends information to the beginning of each line forwarded to an external service. For more information, see File formats in forwarded log files.

Parsing the log file

The following line is a representative example of the data written into your website’s Drupal request log:
