# From a CloudWatch alarm to a pull request.

> Subscribe CoderHelm to the SNS topic that carries your alerts and add rules. An alert a rule takes becomes a run in that rule's repository: CoderHelm analyzes it, makes the change and opens a pull request your team reviews.

*Product view: An alarm routed to a repository, the pull request CoderHelm opened for it, and the recovery paired with the original alert.*

## How alert routing works

1. **Send alerts to SNS.** CloudWatch alarm notifications, AWS Chatbot messages, EventBridge events or plain messages, on a topic in an AWS account your team connected.
2. **Add rules.** Each rule names the alarms or alert text it takes, the repository to fix them in and how to act.
3. **Review the fix.** The pull request goes through normal review. A pull request CoderHelm wrote never merges without a person's approval.

## Alerts and recoveries, paired

When an alarm returns to OK, CoderHelm matches the recovery to the alert that raised it and posts a linked resolved card in Microsoft Teams, so the channel shows what is still open. Alerts no rule takes are posted to Teams only.

## Built to stay calm

- Every message must carry a valid SNS signature, from a topic in an AWS account your team connected
- Alert text is treated as data, never as instructions
- Repeats of the same alert are collapsed into one
- Each rule has a daily run cap, and alert runs stop for the day at your team's alert token budget

## Log findings, every six hours

Connect AWS with a CloudFormation stack that creates a read only role, and CoderHelm scans the CloudWatch log groups you choose every six hours. Each finding has a severity, a summary and a suggested action, and becomes a plan with one click.
