The ColdFusion Logging Page

ColdFusion generates log files you can use to help monitor ColdFusion server activity as well as activity in your ColdFusion applications. ColdFusion generates several different log files, most of which are written to \Cfusion\Log on Windows. All log files are written in comma delimited format.

In addition to logging options, the Logging page contains a few other administrative options.

Log directory

The default location for ColdFusion log files in Windows is cfusion\log. You can specify a new location for ColdFusion log files by entering a new value in the Log Directory list box.

Log slow pages

ColdFusion allows you to track pages in your applications that take longer than a specified length of time to process. You can specify the amount of time ColdFusion allows before writing an entry to the server.log file.

Log files created by ColdFusion

ColdFusion creates nine different log files.
