New in ColdFusion MX: The thread
, date
, and time
attributes are deprecated. Do not use them in new applications. They might not work, and might cause an error, in later releases. (In earlier releases, these attributes determined whether the respective data items were output to the log. In ColdFusion MX, this data is always output.)
This tag logs custom messages to standard or custom log files. You can specify a file for the log message or send messages to the default application or scheduler log. The log message can include ColdFusion expressions. Log files must have the suffix .log and must be located in the ColdFusion log directory.
Log entries are written as comma-delimited lists with these fields:
Values are enclosed in double quotation marks. If you specify No
for the application
attribute, the corresponding entry in the list is empty.
You can disable cflog
tag execution. For more information, see the ColdFusion Administrator, Basic Security page.
The following example logs the name of a user that logs on an application. The message is logged to the file myAppLog.log in the ColdFusion log directory. It includes the date, time, and thread ID, but not the application name.
<Cflog file="myAppLog" application="No"
text="User #Form.username# logged on.">
For example, if a user enters "Sang Thornfield" in a form's username field, this entry is added to the myApplog.log file entry:
"Information","153","02/28/01","14:53:40",,"User Sang Thornfield logged on."
