​
Overview

The AWS CloudWatch integration collects alarms from your AWS accounts and converts them into Warrn alerts. It supports multi-region monitoring, IAM role-based authentication, and automatic severity mapping from alarm states.

​
Setup

  1. Open a service in Warrn and go to Integrations.
  2. Add an AWS CloudWatch integration.
  3. Provide your AWS credentials (access key or IAM role ARN) and select the regions to monitor.
  4. Configure alarm filters and severity mappings.

​
What It Provides

  • Automatic ingestion of CloudWatch alarm state changes.
  • Multi-region support — monitor alarms across AWS regions from one integration.
  • Severity mapping from CloudWatch alarm states to Warrn alert severity levels.
  • Historical alarm data collection on configurable intervals.

​
Authentication

CloudWatch supports two authentication methods:
  • IAM Access Keys — provide an access key and secret with CloudWatch read permissions.
  • IAM Role ARN — assume a cross-account role for secure, credential-free access.

​
Type

Incoming — CloudWatch pushes alarm data into Warrn’s alert pipeline.
