I'm really struggling with debugging failed invocations in AWS EventBridge. It feels like there's no straightforward way to diagnose what's gone wrong, and all I'm getting are vague guidance from AWS to check my configurations. Every time I try to implement EventBridge in a new way, it's a total hassle. Am I missing something here, or is the user experience genuinely that bad? I'm specifically looking for reasons why this process is so painful; I'm not interested in metrics about failure rates or speed.

You can configure failed invocations to end up in a DLQ, which will give you error messages detailing why something failed. But yeah, the entire experience can be a pain, especially with figuring out the necessary IAM permissions for EventBridge to lambda calls. I've spent so many hours untangling that mess.
Have you tried adding a CloudWatch Log Group? You can do this by selecting your EventBridge rule and checking out the target tab. It's crucial for capturing logs, especially for silent failures—seriously, double-checking your rule and target logging can save you a ton of headaches. AWS UX definitely has its issues, though!
What are you using EventBridge for? I typically set up a CloudWatch log for debugging rules. If you’re working with Lambda or HTTP endpoints, a Dead Letter Queue (DLQ) can be a lifesaver to catch errors. Triggering rules directly in the console can help isolate the issue too. I've had a nightmarish time debugging cross-account events, especially with different policies between companies.
There should be a way to pipe failure messages into CloudWatch. If I’m wrong, I’d love for someone to break it down for me like I’m five! It’s the worst when a tool relies on EventBridge for scheduling and fails without any clear reason.
EventBridge acts as an event/message bus, allowing you to send all your errors straight to CloudWatch. You can log everything there and use CloudWatch's tools to create dashboards or even dump logs to S3. There's a pretty helpful guide on monitoring EventBridge via CloudWatch too—maybe check it out!
That sounds great, but I'm really looking for specific error messages, not just metrics on how frequently things fail.
Sounds like you're just patching things together instead of having a seamless experience. Very frustrating!
