This alert triggers when the depth ratio of a Google Cloud Tasks queue exceeds 80%. A high queue depth ratio indicates that tasks are accumulating faster than they are being processed, which could lead to backlogs, delayed task execution, and potential failures in meeting application SLAs. Customization Guidance: Threshold: 80% is chosen to give a warning before the queue reaches full capacity, allowing for preventive action. Queue Specificity: Focus on queues that are critical to your application’s operations. Notification Frequency: Set alerts to trigger as soon as the threshold is exceeded to avoid backlogs. Action: Monitor task processing rates, adjust queue scaling, or investigate potential bottlenecks to ensure tasks are processed efficiently and queues do not become overwhelmed.

This alert triggers when the delay in task attempts within a Google Cloud Tasks queue exceeds 2000 milliseconds (2 seconds). High delays in task attempts may indicate performance bottlenecks or issues in processing tasks, which could lead to slower application responses and potential timeouts. Customization Guidance: Threshold: 2000 ms is selected to catch significant delays that could impact task processing. Adjust this threshold based on the expected performance of your tasks. Queue Specificity: Customize for critical queues where timely task processing is essential. Notification Frequency: Set alerts to trigger promptly upon reaching the threshold to ensure quick response times. Action: Investigate the causes of delays, such as resource constraints or backend service issues, and optimize task processing to reduce latency.
