Logging full stack trace with Monolog

monolog, php

Solution

Actually since version `1.12.0` it is possible to include stacktrace at your log file: there is new method of `LineFormatter` called `includeStacktraces`.

To use this, you need to overwrite default behaviour of monolog formatter:

config.yml

monolog:
    handlers:
        main:
            formatter: your.monolog.service.id
            (rest of config is as usual)

services.yml

services:
    your.monolog.service.id:
        class: Monolog\Formatter\LineFormatter
        calls:
            - [includeStacktraces]

Problem

I use Monolog as a stand-alone library in my application and recently I ran into an issue. Let's say, at some point in my application I catch an exception and I want to log it: ``` $mylogger->error('Exception caught', array('exception' => $exception)); ``` This works perfectly except one tiny thing - it doesn't log whole stack trace. Is it possible to log exception's full stack trace using monolog build-in formatters?
