Eventbridge is not sending messages to sns. IAM based events

Question

Dear Experts,

I have configured eventbridge as mentioned in below link by aws
https://catalog.us-east-1.prod.workshops.aws/workshops/18b3622c-5d4c-45c9-9834-6a7091109072/en-US/advanced-modules/40-monitoring-alert/4-1
My sns and eventbridge are in same region i.e. us-east-1. I can see the necassary permission with action:sns-publish also in my SNS topic. I can send email via this SNS topic when i publish the message manually. However when i create the user or detele via console or cli, i dont see any activity. There is nothing in cloudtrail, in the EB itself i dont see any invocations at all! 
Can someone point out what am i doing wrong?

Answer

Hi,,

Did you create a trail in CloudTrail to record your EventBridge activity as suggested in https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-logging-monitoring.html#eb-info-in-cloudtrail

I would suggest to log all possible API calls

```
DeleteRule
DescribeEventBus
DescribeRule
DisableRule
EnableRule
ListRuleNamesByTarget
ListRules
ListTargetsByRule
PutPermission
PutRule
PutTargets
RemoveTargets
TestEventPattern
```

Many of those calls will give you hints about the progress of your event definition and activation.

I'd also suggest to use CLI:
* https://docs.aws.amazon.com/cli/latest/reference/events/describe-rule.html to confirm your definitions
* https://docs.aws.amazon.com/cli/latest/reference/events/test-event-pattern.html and https://docs.aws.amazon.com/cli/latest/reference/events/put-events.html to validate and test your event pattern when created

**Note:** the use of us-east-1 (you're using it) is critical to get it to work as per https://repost.aws/knowledge-center/eventbridge-rule-triggers-iam-single-region

Best,

Didier
