Hi @mark4 ,
Welcome to Google Cloud Community!
Method 1: Google Cloud Console:
- Go to Monitoring and search for appengine.googleapis.com/system/network/sent_bytes_count.
- Filter by desired date range to compare days visually or calculate differences manually.
Method 2: Stackdriver Logging:
- Enable Stackdriver Logging and filter logs for appengine.googleapis.com/system/network/sent_bytes_count.
- Further filter by date, instance, etc. for specific comparisons.
- Analyze log entries to calculate and compare daily bandwidth manually.
Additional Options:
- Billing History offers overall charges, but not daily breakdowns.
- Command-line tools like gcloud enable automated data extraction and comparison.
