The Web server plug-in problem diagnosis
To view this administrative console page, click Servers > Server Types > Web servers > web_server_name > Plug-in Properties.
On the Configuration tab, you can edit fields. On the Runtime tab, you can look at read-only information.
The Runtime tab is available only when this web server has accessed applications
running on application servers and there is an http_plugin.log file.
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:
Trace - All of the steps in the request process are logged in detail.
Stats - The server selected for each request and other load balancing information relating to request handling is logged.
Warn - All warning and error messages resulting from abnormal request processing are logged.
Error - Only error messages resulting from abnormal request processing are logged.
Debug - All of the critical steps performed in processing requests are logged.
Detail - All of the information about requests and responses are logged.
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.
