PCDOE Implementing service monitoring strategies Practice Question
An organization wants to be alerted when the total size of a Cloud Storage bucket exceeds 1 TB. Which metric should they monitor?
⚠ Common exam trap
Google Cloud often tests the distinction between metrics that measure capacity (total_bytes) versus metrics that measure activity (object_count, request_count) or throughput (network_sent_bytes), leading candidates to confuse object count with total size.

Correct answer & explanation
✓
storage.googleapis.com/storage/total_bytes
The metric `storage.googleapis.com/storage/total_bytes` directly measures the total amount of data stored in a Cloud Storage bucket, including all object data and metadata. Monitoring this metric allows the organization to set an alert threshold at 1 TB (1,099,511,627,776 bytes) to trigger when the bucket exceeds that size. This is the correct metric for tracking storage capacity usage.
