Guzzle logging conflicts with MonologBundle's excluded_404s setting

[thewilkybarkid]

By default Monolog is attached to Guzzle clients through its Log plugin. I've found that Symfony 404s are still logged even thought they should be excluded, and I think that's the problem. (I've hit this when using the param converter, but it would happen elsewhere too.)

My understanding is that as the Guzzle exception happens first (and the Log plugin sets it to the ERROR level) it activates the ErrorLevelActivationStrategy.

It would be useful to have the Guzzle exception ignored if it's followed by a Symfony 404.
