From 0f343c41850b6cf827fd7b2251ba31492da7ffa3 Mon Sep 17 00:00:00 2001 From: Sunil Thaha Date: Mon, 1 Sep 2025 14:33:00 +1000 Subject: [PATCH 1/8] feat(platform): implement experimental redfish power monitoring Add Redfish BMC integration to monitor bare metal power consumption independently of workload attribution. Introduces `kepler_platform_watts` metric to track total chassis power from multiple BMCs per node. Key Changes: * Redfish service with staleness-based caching and multi-chassis support * Node ID resolution (CLI flag > redfish NodeName > K8s node name > hostname) * Thread-safe on-demand power collection with configurable HTTP timeouts * Prometheus platform collector with chassis_id, bmc, and node_name labels * Mock server for testing without BMC hardware Dependencies: Added

Validation Process + +```bash +# Run fixture validation tests +go test ./internal/platform/redfish/testdata -v + +# Validate individual fixture +go test -run TestIndividualFixtures/DellPower +``` + +### Capturing Real BMC Data + +For development purposes, you can capture real BMC responses: + +```bash +# Build with manual tag to include real capture utilities +go test -tags=manual ./internal/platform/redfish/testdata -run TestCapture +``` + +**Security Note**: Real capture utilities sanitize sensitive data (UUIDs, serial numbers, IPs) before creating fixtures. + +### Adding New Fixtures + +1. **From Real BMC**: Use `real_capture.go` utilities to capture authentic responses +2. **Manual Creation**: Create JSON following Redfish schema patterns +3. **Validation**: Ensure new fixtures pass `ValidateFixture()` tests +4. **Testing**: Add test scenarios using the new fixture + +### Fixture Structure Guidelines + +#### Power Fixtures Must Include + +- `@odata.type`: Redfish Power schema type +- `Id`: Resource identifier +- `PowerControl`: Array with at least one power control object +- `PowerConsumedWatts`: Current power consumption value + +#### Error Fixtures Must Include + +- `error`: Object with error details +- `code`: Redfish error code +- `message`: Human-readable error message + +### API Evolution Strategy + +When Redfish API changes: + +1. **Schema Updates**: Update gofish dependency to latest version +2. **Fixture Migration**: Use validation tests to identify incompatible fixtures +3. **Real Data Refresh**: Re-capture from updated BMCs when possible +4. **Backward Compatibility**: Maintain old fixtures for testing legacy scenarios + +### Best Practices + +- **Minimal Fixtures**: Include only necessary fields for test scenarios +- **Vendor Diversity**: Test against multiple BMC vendor formats +- **Error Coverage**: Include various error conditions +- **Real-World Data**: Base fixtures on actual BMC responses when possible +- **Security**: Never include real credentials, serial numbers, or network details + +### Running Validation + +Validation is automatically run in CI, but you can run it locally: + +```bash +# Validate all fixtures +go test ./internal/platform/redfish/testdata -run TestFixtureValidation + +# Validate specific vendor fixtures +go test ./internal/platform/redfish/testdata -run TestIndividualFixtures/Dell + +# Check for JSON syntax errors +go test ./internal/platform/redfish/testdata -run TestErrorFixtures +``` + +### Integration with Gofish + +Our fixtures leverage gofish's approach: + +- **Struct Compatibility**: All fixtures validate against gofish structs +- **Error Handling**: Use gofish's error response patterns +- **Schema Compliance**: Follow DMTF Redfish schema standards +- **Vendor Support**: Cover vendor-specific response variations + +This ensures our tests accurately represent real-world BMC behavior while maintaining reliability and maintainability.
