We have 50+ pipelines running across different regions and it's becoming impossible to track failures. I want to build a centralized CloudWatch Dashboard that shows pipeline success rates and build durations. Is it possible to integrate AWS X-Ray to see where the latency is occurring within the pipeline stages themselves, or is X-Ray only for application-level tracing?

For high-level monitoring, you should use 'CloudWatch Metrics' which CodePipeline publishes automatically. You can track 'PipelineExecutionFailure' and 'Duration' metrics. For a centralized view, use a cross-region CloudWatch dashboard. Regarding X-Ray, while it’s primarily for applications, you can use the X-Ray SDK inside your CodeBuild scripts to create custom segments. This allows you to trace exactly how long a specific unit test or integration suite takes. It’s a great way to identify "flaky" tests that are slowing down your overall delivery cycle across all 50 pipelines.
Would it be better to use 'EventBridge' to catch pipeline state changes and send them to a Lambda function that updates a DynamoDB table? That way, we could build a custom frontend for our stakeholders. Is CloudWatch flexible enough for that kind of custom reporting?
Check out 'ServiceLens' in CloudWatch. It integrates X-Ray and CloudWatch metrics into one view, which might save you the trouble of building a custom dashboard from scratch.
ServiceLens is a hidden gem! It’s perfect for seeing the correlation between a pipeline deployment and a sudden spike in application errors or latency.
CloudWatch is great for metrics, George, but for "State" tracking, your EventBridge + Lambda idea is much more powerful. We actually do this to send real-time alerts to Slack whenever a production pipeline fails. It allows us to include the specific commit message and author in the notification, which you can't easily do with standard CloudWatch Alarms. It makes the feedback loop much tighter for the dev team.
