> Logging:
>
> Logging in Tomcat is quite flexible; we can either have a log
> file per module (example: ContextManager) or we can have one
> for Servlets and one for Jasper, or we can just have one
> tomcat.log for both Servlet and Jasper. Right now there are
> three standard log streams, "tc_log", "servlet_log", and
> "JASPER_LOG".
>
> Path:
>
> The file to which to output this log, relative to
> TOMCAT_HOME. If you omit a "path" value, then stderr or
> stdout will be used.
>
> Verbosity:
>
> Threshold for which types of messages are displayed in the
> log. Levels are inclusive; that is, "WARNING" level displays
> any log message marked as warning, error, or fatal. Default
> level is WARNING.
>
> verbosityLevel values can be:
> FATAL
> ERROR
> WARNING
> INFORMATION
> DEBUG
>
> Timestamps:
>
> By default, logs print a timestamp in the form "yyyy-MM-dd
> hh:mm:ss" in front of each message. To disable timestamps
> completely, set 'timestamp="no"'. To use the raw
> msec-since-epoch, which is more efficient, set
> 'timestampFormat="msec"'. If you want a custom format, you
> can use 'timestampFormat="hh:mm:ss"' following the syntax of
> java.text.SimpleDateFormat (see Javadoc API). For a
> production environment, we recommend turning timestamps off,
> or setting the format to "msec".
>
> Custom Output:
>
> "Custom" means "normal looking". "Non-custom" means
> "surrounded with funny xml tags". In preparation for
> possibly disposing of "custom" altogether, now the default is
> 'custom="yes"' (i.e. no tags)
>
> Per-component Debugging:
>
> Some components accept a "debug" attribute. This further
> enhances log output. If you set the "debug" level for a
> component, it may output extra debugging information.

> The default is "true", so you must specify "false" to prevent
> the debug information from appearing. Since the debugging
> information reveals internal details about what Tomcat is serving,
> set showDebugInfo="false" if you wish increased security.
