Configuring debugging in the ColdFusion Administrator

Enable Robust Exception Information

Enables the display of the following information when ColdFusion displays the exception error page. (Cleared by default.)

• Path and URL of the page that caused the error
• Line number and short snippet of the code where the error was identified
• Any SQL statement and data source
• Java stack trace

Enable Debugging

Enables debugging output. When this option is cleared, no debugging information is displayed, including all output of cftrace and cftimer calls. (Cleared by default.)You should disable debugging output on production servers. Doing so increases security by ensuring that users cannot see debugging information. It also improves server response times. You can also limit debugging output to specific IP addresses; for more information, see Debugging IP Addresses page.

Select Debugging Output Format

Determines how to display debugging output:

• The classic.cfm template (the default) displays information as plain HTML text at the bottom of the page.
• The dockable.cfm template uses DHTML to display the debugging information using an expanding tree format in a separate window. This window can be either a floating pane or docked to the browser window. For more information on the dockable output format, see Using the dockable.cfm output format in Using debugging information from browser pages.

Report Execution Times

Lists ColdFusion pages that run as the result of an HTTP request and displays execution times, ColdFusion also highlights in red pages with processing times greater than the specified value, and you can select between a summary display or a more detailed, tree structured, display.

General Debug Information

Displays general information about the request: ColdFusion Version, Template, Time Stamp, User Locale, User Agent, User IP, and Host Name.

Database Activity

Displays debugging information about access to SQL data sources and stored procedures. (Selected by default.)

Exception information

Lists all ColdFusion exceptions raised in processing the request. (Selected by default.)

Tracing information

Displays an entry for each cftrace tag. When this option is cleared, the debugging output does not include tracing information, but the output page does include information for cftrace tags that specify inline="Yes". (Selected by default.)For more information on using the cftrace tag, see Using the cftrace tag to trace execution.

Variables

Enables the display of ColdFusion variable values. When this option is cleared, disables display of all ColdFusion variables in the debugging output. (Selected by default.)When enabled, ColdFusion displays the values of variables in the selected scopes. You can select to display the contents of any of the ColdFusion scopes except Variables, Attributes, Caller, and ThisTag. To enhance security, Application, Server, and Request variable display is disabled by default,

Enable Performance Monitoring

Allows the standard NT Performance Monitor application to display information about a running ColdFusion application server.

Enable CFSTAT

Enables you to use of the cfstat command line utility to monitor real-time performance. This utility displays the same information that ColdFusion writes to the NT System Monitor, without using the System Monitor application. For information on the cfstat utility, see Configuring and Administering ColdFusion.
