Proactive monitoring for Amazon Redshift Serverless using AWS Lambda and Slack alerts
Big Data Blog
This article explains how to build a serverless monitoring solution for Amazon Redshift Serverless that detects performance anomalies and sends Slack alerts.
- EventBridge triggers Lambda function every 15 minutes to collect Redshift metrics
- Lambda gathers queued queries, running queries, RPUs, storage, connections, and slow queries
- Metrics compared against configurable thresholds; alerts sent via SNS to Slack
- CloudFormation template automates deployment of all required resources
- Solution costs approximately $0.33 USD monthly with default configuration
- Supports optional VPC deployment and KMS encryption for enhanced security
- Requires granting Lambda IAM role sys:monitor role in Redshift for data access
This serverless approach enables early detection of Redshift performance issues without dashboard monitoring, reducing operational overhead and costs.
