AWS ECS Monitor

Production health monitoring and log analysis for AWS ECS services.

What It Does

• Health Checks: HTTP probes against your domain, ECS service status (desired vs running), ALB target group health, SSL certificate expiry
• Log Analysis: Pulls CloudWatch logs, categorizes errors (panics, fatals, OOM, timeouts, 5xx), detects container restarts, filters health check noise
• Auto-Diagnosis: Reads health status and automatically investigates failing services via log analysis

Prerequisites

• aws CLI configured with appropriate IAM permissions:
  • ecs:ListServices, ecs:DescribeServices
  • elasticloadbalancing:DescribeTargetGroups, elasticloadbalancing:DescribeTargetHealth
  • logs:FilterLogEvents, logs:DescribeLogGroups
• curl for HTTP health checks
• python3 for JSON processing and log analysis
• openssl for SSL certificate checks (optional)
