Pull Request Review: Update OpenTelemetry Collector to v0.141.0

Summary

This PR updates the OpenTelemetry Collector Contrib image from v0.140.1 to v0.141.0 in the Raspberry Pi monitoring stack configuration.

✅ Code Quality & Best Practices

LGTM - The change follows best practices:

• ✅ Single responsibility: Only updates the Docker image version
• ✅ Clear intent: Automated dependency update via Renovate bot
• ✅ Consistent: Only one file references this image (verified across all YAML files)
• ✅ Proper versioning: Uses explicit version tags (not latest)

🔍 Potential Issues & Considerations

1. Configuration Compatibility ⚠️

Status: Likely safe, but verification recommended

The current OTEL Collector configuration (grafana-config/otel-collector.yaml) uses standard, stable components:

• otlp receiver (gRPC/HTTP)
• batch processor
• otlp/tempo exporter
• prometheusremotewrite exporter
• health_check extension

These are core components that rarely have breaking changes in minor version updates.

Recommendation: Test the stack after deployment to ensure:

# Verify OTEL Collector starts successfully
docker compose -f docker-compose.monitoring-rpi.yml logs otel-collector

# Check health endpoint
curl http://localhost:13133

# Verify telemetry pipeline
docker compose -f docker-compose.monitoring-rpi.yml ps

2. Release Notes ℹ️

According to the PR description, v0.141.0 adds:

• healthcheck and pprof extensions to the eBPF distribution

Impact: None - These are extensions for the eBPF distro, not the contrib distro used in this project. Your configuration already uses the health_check extension.

3. Testing Coverage ⚠️

The repository has monitoring stack tests:

• tests/integration/test_monitoring_stack.py
• scripts/test-monitoring-stack.sh
• .github/workflows/test-monitoring-stack.yml

Recommendation: Ensure CI tests pass before merging. If CI doesn't automatically test this file, consider running integration tests manually on Raspberry Pi.

🚀 Performance Considerations

Status: Positive

Minor version updates typically include:

• Performance improvements
• Bug fixes
• Security patches

The resource limits in your configuration are already optimized:

mem_limit: 512m
cpus: '0.5'

No performance concerns expected from this update.

🔒 Security Concerns

Status: Good practice

Pros:

• ✅ Keeping dependencies up-to-date reduces security vulnerabilities
• ✅ OpenTelemetry project has active security monitoring
• ✅ The collector runs with appropriate resource limits

Recommendations:

1. Monitor CVE databases after deployment for any reported vulnerabilities
2. Review upstream changelog for security-related fixes (if available)
3. Verify security context remains intact (your config doesn't specify user, relying on image defaults)

📊 Test Coverage

Status: Tests should verify integration

Existing tests should cover:

• OTLP endpoint availability (ports 4317, 4318)
• Health check endpoint (port 13133)
• Integration with Tempo and Prometheus
• Trace and metric pipeline functionality

Recommendation: Run the monitoring integration tests:

# Before merging
bash scripts/test-monitoring-stack.sh

📝 Final Verdict

Recommendation: ✅ APPROVE with verification

This is a low-risk, routine dependency update that:

• Follows semantic versioning (minor version bump)
• Uses stable, well-tested components
• Includes no breaking changes in your configuration scope
• Aligns with security best practices

Pre-merge checklist:

• CI tests pass
• Manual testing on Raspberry Pi (if possible)
• Monitor logs after deployment for any warnings
• Verify all telemetry pipelines work (traces to Tempo, metrics to Prometheus)
