- Add prometheus-slo-rules.test.yml with unit tests for SLO recording and alerting rules - Add prometheus-rules-test job to CI pipeline - Check syntax of prometheus-slo-rules.yml and alerts.yaml - Run promtool unit tests for critical alerting rules - Fail CI on rule syntax errors
- Add runbook_url to all alert rules in alerts.yaml - Create comprehensive runbooks in docs/runbooks/ for: - API performance (response time, error rate, throughput) - Cache performance (hit rate) - Database performance (query latency, connection pool) - Contract performance (gas costs) - System health (service down, memory, CPU) - Performance regression detection - Each runbook includes: alert meaning, impact, investigation steps, remediation
- Add check-slo-compliance.js script to query Prometheus for SLO metrics - Script checks error budget remaining for all SLOs - Blocks production deployment if error budget exhausted (< 0%) - Supports CONFIRM_SLO_OVERRIDE=yes for emergency deploys with approval - Integrated into deploy workflow for production environment - Provides clear feedback on SLO status and error budget
- Add deploy-testnet target with confirmation prompt - Add deploy-mainnet target with additional CONFIRM_MAINNET=yes requirement - Separate testnet and mainnet deployment targets for safety - Testnet requires single confirmation: 'Are you sure? [y/N]' - Mainnet requires both confirmation prompt AND CONFIRM_MAINNET=yes env var - Prevents accidental mainnet deployments - Builds optimized contract before deployment
