Metrics, Alarms & Dashboards
- CloudWatch metrics: namespaces, dimensions, standard vs detailed monitoring resolution
- Custom metrics: PutMetricData API, EMF (Embedded Metric Format) from Lambda and ECS
- CloudWatch Alarms: threshold, anomaly detection, composite alarms
- SNS integration: alarm notifications to Slack, PagerDuty, Lambda
- CloudWatch Dashboards: cross-account, cross-region, automatic dashboards
- Container Insights: EKS and ECS metrics — pod, task, and container level
- Lambda metrics: duration, errors, throttles, concurrent executions
- EC2 and RDS metrics worth monitoring: what to alarm on and what to ignore
- CloudWatch Synthetics: canary scripts for availability monitoring
Logs Insights, Contributor Insights & X-Ray
- CloudWatch Logs: log groups, log streams, retention, metric filters
- Logs Insights: query syntax — filter, stats, sort, parse, dedup
- Useful queries: error rate, p99 latency from logs, top callers
- Subscription filters: streaming logs to Lambda, Kinesis, OpenSearch
- Contributor Insights: identifying top talkers — IPs, users, API callers
- CloudWatch Application Signals: SLO management for AWS workloads
- X-Ray integration: trace map, segment analysis, sampling rules
- CloudWatch Evidently: feature flags and A/B experiments
- Cross-account observability: CloudWatch cross-account sink configuration
- Cost control: log retention policies, metric resolution trade-offs
AWS engineers who get full operational value from CloudWatch — meaningful alarms, efficient log queries, and dashboards that show what is actually happening.
- Configure CloudWatch Alarms with correct thresholds and composite alarm logic
- Query CloudWatch Logs Insights for error rates, latency distributions, and top talkers
- Build cross-service dashboards using Container Insights and Lambda metrics
- Set up X-Ray tracing and correlate traces with logs and metrics
