I really struggle with debugging failed EventBridge invocations. It feels like there's no clear way to figure out what went wrong, and often I'm left without even a useful error message. AWS just suggests reviewing my configuration, which isn't very helpful. Every time I approach EventBridge for a new task, the experience is painfully frustrating. Am I missing something here, or is the user experience just that bad? Also, I'm more interested in understanding the reasons behind failures rather than just metrics about them.

You might want to check if you can route failure messages into CloudWatch. If you're stuck, just reading through AWS’s resources can feel like a maze with no clear path—especially when other tools are involved and don’t provide the clarity you need.
EventBridge works like a message bus, and you can dump all errors into CloudWatch. From there, you can create dashboards or even push logs to S3. It offers various tools to help monitor, but you might only get metrics instead of detailed error messages. Here’s an AWS link that dives into monitoring:
One tip is to set up a CloudWatch log group for your EventBridge rule and target. It’s essential for tracking what's going on. Without it, you won’t see much, and believe me, the silent failures can be infuriating!
It’s all about how you set things up for testing. I usually use CloudWatch logs for debugging. If you're invoking Lambda or HTTP endpoints, consider using a Dead Letter Queue (DLQ) to catch errors. Triggering the rules in the console can also help isolate issues. Be especially careful with cross-account events, as they can get tricky due to the necessary policies.
So it's really just a temporary fix instead of a proper solution, huh?
You can configure failed invocations to go to a DLQ, where you can find error messages detailing what went wrong. Although, I agree, the whole experience feels a bit clunky, especially when it comes to setting up IAM permissions for EventBridge to invoke Lambdas. I’ve spent way too long debugging those permissions.
These metrics don’t help much if you need concrete error messages! They just tell you when and maybe how often something fails, not the exact issue.
