Global: Cloud Monitoring Metrics may be unavailable or underreported for Cloud Pub/Sub

Summary: Global: Cloud Monitoring Metrics may be unavailable or underreported for Cloud Pub/Sub Description: We are experiencing an issue with Google Cloud Pub/Sub beginning on Friday, 2022-04-22 19:10 US/Pacific. There is no known impact on Cloud Pub/Sub administrative, publish, or subscribe operations at this time. Engineering is continuing to investigate the issue. We will provide an update by Saturday, 2022-04-23 10:00 US/Pacific with current details. We apologize to all who are affected by the disruption. Diagnosis: Customers impacted by this issue may see Cloud Monitoring metrics for Cloud Pub/Sub that show no or underreported values. Any alerting based on these metrics may fire erroneously. Workaround: Non-Cloud-Pub/Sub metrics and logs on publish and subscriber clients can be used as a proxy to ensure that publishing and subscribing is still behaving as expected. For example, metrics available for clients running on GCE include: instance/cpu/utilization instance/network/received_bytes_count instance/network/sent_bytes_count
