Seeking Reference for AWS Troubleshooting Guide Across Core Operational Categories

0

Hello,

I'm currently preparing a comprehensive troubleshooting guide for common issues across several key categories in AWS environments. The goal is to build a structured and reusable knowledge base that covers a variety of operational scenarios.

The categories I'm focusing on include:

  1. Storage & Data Management
  2. Security & Compliance
  3. Networking
  4. Automation & Optimization
  5. Compute
  6. Monitoring & Reporting
  7. Foundational IT

The troubleshooting guide is structured with the following columns:

  1. Category
  2. Issue Description
  3. Symptoms
  4. Root Cause Analysis
  5. Resolution Procedures
  6. Helpful Tools or Resources
  7. Comments

Example Troubleshooting Guide:

1NetworkingApplication on Amazon EC2 instance - connectivity issue due to network access rules.
https://www.google.com/search?q=ec2-XX-XXX-XX-XX.region.compute.amazonaws.com
https://www.google.com/search?q=ec2-XX-XXX-XX-XX.region.compute.amazonaws.com took too long to respond. ERR_CONNECTION_TIMED_OUT"		The Security Group associated with the EC2 instance, or a Network Access Control List (NACL) associated with the subnet, is blocking inbound traffic on the required port (e.g., HTTP/80, HTTPS/443, SSH/22). This could be due to recent changes, misconfiguration, or an overly restrictive default.

<port>
<port>
"Security Groups act as a virtual firewall for your instance, while NACLs act as a firewall for subnets. Remember that Security Groups are stateful (response traffic is automatically allowed), while NACLs are stateless (both inbound and outbound rules must be explicitly defined). Start by checking Security Groups as they are more commonly the culprit."

If any of you have created or come across a similar AWS troubleshooting guide, I would be grateful if you could share it for reference. I'm especially interested in examples that align with this structured format.

Looking forward to learning from your experience!

AWS offers several tools and resources to help with troubleshooting common issues across your AWS environment. Here are some options that align with your structured troubleshooting guide approach:

AWS Support Automation Workflows (SAW) provides self-service diagnosis and remediation for common issues in AWS environments. SAW leverages AWS Systems Manager and offers curated automation runbooks that simplify troubleshooting processes across various AWS services including EC2, S3, EKS, and ECS. These runbooks can help with issues like SSH connectivity problems, disk usage analysis, permission errors, and collecting essential logs.

For EC2 instances specifically, AWS Systems Manager can diagnose and help remediate several categories of management issues:

  • Security group configuration and HTTPS communications issues
  • DNS or DNS host name configuration problems
  • VPC endpoint configuration issues

Amazon Q Developer (currently in preview) is a generative AI-powered capability that can guide you through operational diagnostics and automate root cause analysis. It integrates with CloudWatch and AWS Systems Manager to provide a unified troubleshooting experience. When an alarm is triggered, Amazon Q can help identify relationships between resources, create topology maps to pinpoint root causes, and suggest remediation actions including Systems Manager Automation runbooks.

AWS also emphasizes the importance of designing systems with operations in mind to solve issues quickly and learn from them. This includes predefining runbooks for routine activities and playbooks for guiding issue resolution, using operations as code features, and maintaining situational awareness.

These tools and approaches can help you build your comprehensive troubleshooting guide across the categories you've identified, providing structured ways to identify symptoms, analyze root causes, and implement resolutions.
