// Usage

$app['monitoring']->application500Error() // This will send a value of 1 to Http500Error metric, with the instance-id and the BBCEnvironment as values too

$app['monitoring']->application404Error() // This will send a value of 1 to Http404Error metric, with the instance-id and the BBCEnvironment as values too

$app['monitoring']->applicationError() // This will send a value of 1 to applicationError metric, with the instance-id and the BBCEnvironment as values too. This is used as a catchAll error for anything not a 404 or a 500

$app['monitoring']->customApplicationError('your error message') // This will send a value of 1 to applicationError metric, with the instance-id and the BBCEnvironment as values too, it will also send error: your error message as another dimension
