Custom log files are not gzipped automatically

Issue

You have created a custom log file and you notice that it is not gzipped every day. 

Cause

Acquia Cloud archives log files by file name, and won’t archive files in the logs directory that not use one of these default names.

• access.log
• error.log
• drupal-requests.log
• drupal-watchdog
• php-errors.log
• drush-cron.log
