wrapper.logfile.format

Format to use for logging to the log file. Logging was intentionally kept simple. The format consists of the tokens `'L'` for log level, `'P'` for prefix, `'D'` for thread, `'T'` for time, `'Z'` for millisecond time, and `'M'` for message. If the format contains these values then it will be included in the format. The order of the tokens does not affect the way the log appears, but the `'M'` token should usually be placed last as it is the only column without a uniform width. If the property is missing or commented out, then the default value `'LPTM'` will be used. Setting the property to a blank value will cause file logging to be disabled.

Example:

    wrapper.console.format=PM

The following examples demonstrate the output with various settings. Note that the first two lines are output from the Wrapper, while the last is output from the JVM.

Example output where `wrapper.console.format=LPZM`

    STATUS | wrapper  | 2001/12/11 13:45:33.560 | --> Wrapper Started as Console
    STATUS | wrapper  | 2001/12/11 13:45:33.560 | Launching a JVM...
    INFO   | jvm 1    | 2001/12/11 13:45:35.575 | Initializing...

Example output where `wrapper.console.format=LPTM`

    STATUS | wrapper  | 2001/12/11 13:45:33 | --> Wrapper Started as Console
    STATUS | wrapper  | 2001/12/11 13:45:33 | Launching a JVM...
    INFO   | jvm 1    | 2001/12/11 13:45:35 | Initializing...

Example output where `wrapper.console.format=PTM`

    wrapper  | 2001/12/11 13:45:33 | --> Wrapper Started as Console
    wrapper  | 2001/12/11 13:45:33 | Launching a JVM...
    jvm 1    | 2001/12/11 13:45:35 | Initializing...

Example output where `wrapper.console.format=PM`

    wrapper  | --> Wrapper Started as Console
    wrapper  | Launching a JVM...
    jvm 1    | Initializing...

Example output where `wrapper.console.format=M`

    --> Wrapper Started as Console
    Launching a JVM...
    Initializing...

Example output where `wrapper.console.format=`

    < No Output >

The `'D'` format token is mainly useful for debugging the Wrapper. It displays which internal Wrapper thread output a given log message. It does not show information about Java threads. The `'D'` format token was added in version 3.1.0.

Example output where `wrapper.console.format=LPDTM`

    STATUS | wrapper  | main    | 2001/12/11 13:45:33 | --> Wrapper Started as Console
    STATUS | wrapper  | main    | 2001/12/11 13:45:33 | Launching a JVM...
    INFO   | jvm 1    | main    | 2001/12/11 13:45:35 | Initializing...
