Plug-in logging

Specifies the location and name of the http_plugin.log file. Also specifies the scope of messages in the log.

The log describes the location and level of log messages that are written by the plug-in. If a log is not specified within the configuration file, then, in some cases, log messages are written to the web server error log.

Log level: The level of detail of the log messages that the plug-in should write to the log. You can specify one of the following values for this attribute:

If a Log level is not specified, the default value Error is used.

Be careful when setting the level to Trace. A lot of messages are logged at this level which can cause the disk space/file system to fill up very quickly. A Trace setting should never be used in a normally functioning environment as it adversely affects performance.
