Symfony app engine standard - monolog

[chuckchick]

Where can I see the 'google_cloud' monolog handler below used?
To me it seems whether it's there or not the result is the same for me.

When an uncaught exception is hit, I do see the error report in the GCP console but that happens even without the 'google_cloud: ' section.

        type: service

According to the symfony docs for adding a custom handler, this is how it's done. If it's not working, I'd have to debug further, but this looks accurate to me.
