Oldest Unacked Message Age Value less than 24 hours.
Product: Cloud Pub/Sub
Rule class: BP - Best practice, opinionated recommendations
Description
Increasing Oldest Unacked Message Age indicates presence of a message on the subscription that has not been processed yet; either undelivered, being nacked by the subscriber or overall being acked in an untimely manner from the subscriber causing expiring acks.
Remediation
Configure subscribers to pull from the subscription and ensure messages are successfully processed and acked. Alternatively ensure push endpoints or destinations work correctly to receive and ack messages.
