Default Appenders Guide

Default Appender

Log.apex has a default appender, Log.DefaultAppender, which outputs logging information toSystem.debug.

The default appender outputs messages with current class name, current method name, current line number and current column number.

11:18:39.50 (103576326)|USER_DEBUG|[984]|DEBUG|AnonymousBlock.(unknown method) Line 2 Column 1 - debug message

Options

We can customize how the prefix message looks like:

[
    {
        "patterns": [ "test" ],
        "level": "Debug",
        "appenders": [
            {
                "name": "Log.DefaultAppender",
                "options": {
                    "prefixPattern": "%t - %m - %l - %c - "
                }
            }
        ]
    }
]

And debug like this:

logger.debug('message');

The output will be like 'CurrentClassName - CurrentMethodName - CurrentLineNumber - CurrentColumnNumber - message'.
