This seems to be a bug in MonologBundle, or a misuse of it. In any case not something I can fix here. See https://github.com/symfony/monolog-bundle/blob/master/DependencyInjection/MonologExtension.php#L282 it uses MongoClient if you don't define a service id. IMO you should pass a service id (it doesn't have to be ODM, just could be a service defining a MongoDB\Client instance.
