Working with Logs

The Logs page (Monitoring | Logs) is a log viewer for developers to view log information directly from the UI. From this page you can view, filter, navigate, export and refresh logs.

Advanced users can also add logs to the list of logs to display in the Log Display area.

Note for Linux users:

The Apache access and error logs cannot be viewed on the Monitoring | Logs page without adding permissions for the Zend Server user ( 'zend') to read the log files:
Debian: /var/log/apache2/access.log, /var/log/apache2/error.log
Redhat - /var/log/httpd/access_log, /var/log/httpd/error_log
