gcs-monitor
Just a little application that was created to test out some things with Prometheus and Uber Zap.
This will listen to a Google Cloud Platform Pub/Sub Queue that has been configured for notifications around a Google Cloud Storage bucket. Documentation about this can be found here.
There is an assumption here that you already have a GCP account, project, buckets and know how it all works to add the Pub/Sub notifications onto a bucket.
