<\/span>Overview<\/span><\/h2>\n\n\n\n

WEXAL\u00ae Page Speed Technology (hereinafter referred to as \"PST\") has various logs to which it outputs operating status. You can use these logs to check the status of the system and to find out the cause of any problems that may be occurring.<\/p>\n\n\n\n

There are two types of logs: system-wide logs and PST profile logs.<\/p>\n\n\n\n

<\/span>PST Profile Logs<\/strong><\/span><\/h3>\n\n\n\n

PST Profile Logs include the web server access log, the error log, the PST log, the proxy log, the webfont log, and the reverse proxy log.<\/p>\n\n\n\n

<\/span>System-wide Logs<\/strong><\/span><\/h3>\n\n\n\n

The system-wide logs include the logs output by WEXAL services and the PST Manager log.<\/p>\n\n\n\n

<\/span>Web Server Access Log<\/span><\/h2>\n\n\n\n

The web server access log records client access to the web site.<\/p>\n\n\n\n

In addition, when PST is enabled, the status of optimization strategies is recorded in the web server access log. In environments where PST is not applied or enabled, PST information will not be recorded.<\/p>\n\n\n\n
