CloudWatch (Contextual)
Connects to CloudWatch via AWS credentials to pull alarms and metrics. Used by Warrnagen during investigations to check metric state.
1
Add to a service
Open a service or team in Warrn. Go to the Integrations tab and add AWS CloudWatch**.
2
Enter AWS credentials
Provide an AWS Access Key ID, Secret Access Key, and optionally an IAM Role ARN. Select your AWS region.
CloudWatch SNS (Incoming)
Receives CloudWatch alarm notifications via SNS. When an alarm enters ALARM state, Warrn creates an alert. When it returns to OK or INSUFFICIENT_DATA, Warrn auto-resolves the matching alert.
1
Add the integration in Warrn
Open a service or team in Warrn. Go to the Integrations tab and add CloudWatch SNS**. Copy the generated webhook URL.
2
Create an SNS subscription
In AWS, create an SNS topic (or use an existing one). Add an HTTPS subscription pointing to the Warrn webhook URL.
3
Configure CloudWatch alarms
Set your CloudWatch alarms to send notifications to the SNS topic for both ALARM and OK actions. This enables auto-resolve.
Configure alarms for both ALARM and OK actions. Without the OK action, Warrn can create alerts but not auto-resolve them.
