/var/cpanel/accounting.log

This file contains records of cPanel account actions, such as creation and deletion.

The system prints these records in the following standardized order:

1
2

Thu Jun 11 13:33:19 2015:ADDRESELLER:root:root:example.com:example
Fri Oct 30 12:57:29 2015:CHANGEOWNER:root:root:example.com:example:root:example

  1. Time and date — The time and date when you or another user on your server performed the account action in WD MM DD:HH:mm:SS YYYY format, where:

    • WD represents the day of the week.
    • MM represents the month.
    • DD represents the day of the month.
    • HH represents the hour in 24-hour time.
    • mm represents the minute.
    • SS represents the second.
    • YYYY represents the year.

  2. Operation — The action that you performed. For example, all of the following are potential actions:

    • CREATEAPITOKEN means that you have created an API token.
    • ADDRESELLER means that you have added a reseller.
    • CHANGEOWNER means that you have changed an account’s owner.

  3. Operating account — The account with which you performed the action. For example, if you were logged in as example when you suspended an account, the third value in the accounting.log entry would be example.

  4. System account — The account which performed the action. Most internal actions execute as root, even if you are not logged in as the root user.

    Note:
    Some actions output the operating account into the fourth field instead of the system account.

Some account actions add extra fields. The following operations print extra fields:

Webservers

Apache

Note:

If your system manages many domains, we recommend that you enable piped logging to reduce the number of log files that Apache manages. Piped logging allows you to pipe Apache access logs to a separate process so that Apache does not need to restart every time that it processes the logs.

You can enable piped logging in the Piped Log Configuration section of WHM’s Apache Configuration interface (WHM » Home » Service Configuration » Apache Configuration).

/etc/apache2/logs/domlogs/USER

This directory contains the log data for the user’s account, which exists on a webserver that runs EasyApache 4.

The system creates this directory when the cPanel Log Rotation Configuration (cpanellogd) daemon compresses and archives the data that resides in the /etc/apache2/logs/domlogs/domain-ssl_log and the /etc/apache2/logs/domlogs/domain files. This process begins when the /usr/local/cpanel/scripts/upcp script runs and the system analyzes the log data.

Note:

You can also perform this process for individual users with the /usr/local/cpanel/scripts/runweblogs command.

The system also performs the following actions:

  • Adds a link to the /etc/apache2/logs/domlogs/USER directory in the /home/USER/access_logs directory.
  • Adds a symlink to the log data backup file in the user’s /home/USER/logs directory during the archive process.
    • This symlink allows you to access this file while the system archives the file.
    • The symlink’s name reflects the log file’s name, and may contain a .bkup file extension.
