AWS DevOps Agent aids Network Firewall troubleshooting by correlating logs and configurations
Key points
- AWS DevOps Agent correlates firewall data for troubleshooting.
- It integrates with CloudWatch alarms via webhooks.
- The agent identifies root causes and suggests mitigation plans.
- A CDK app is provided to reproduce troubleshooting scenarios.
Automated Troubleshooting for Network Firewall
AWS DevOps Agent now assists in troubleshooting disruptions within AWS Network Firewall. When network connectivity issues arise due to rule changes, the agent automates the process of pinpointing the cause. This reduces the manual effort typically required to inspect various points in the traffic path.
How AWS DevOps Agent Works
The AWS DevOps Agent functions by correlating firewall configurations, flow logs, and recent API calls recorded in AWS CloudTrail. When an Amazon CloudWatch alarm triggers, the agent receives the alert via a webhook. It then reads relevant firewall data through AWS APIs, links drops to recent API activity, and provides a root cause analysis along with a mitigation plan.
Addressing Complex Network Issues
Network disruptions can stem from various sources, including stateless and stateful rule engines, domain rules, and routing configurations. The agent helps differentiate between these complex scenarios, which previously required extensive manual correlation of logs and configurations. This automation aims to resolve connectivity issues in minutes rather than hours.
Reproducible Troubleshooting Scenarios
A provided AWS Cloud Development Kit (CDK) app deploys an environment that allows users to reproduce three specific Network Firewall failure scenarios: a domain deny list blocking an endpoint, a stateless rule priority misconfiguration, and an asymmetric cross Availability Zone routing drop. This enables users to follow along and apply the troubleshooting techniques with DevOps Agent in their own accounts.
