Objective: To enhance observability, monitoring, and tracing capabilities in Harness by integrating OpenTelemetry, similar to the functionality provided by CloudBees Jenkins. This integration will allow users to gain deeper insights into pipeline performance, application behavior, and system health across distributed environments. Background: OpenTelemetry is an open-source observability framework that provides standardized APIs, SDKs, and tools for collecting and exporting telemetry data (traces, metrics, and logs). It is widely adopted for monitoring distributed systems and microservices architectures. Harness, as a Continuous Delivery (CD) and Continuous Integration (CI) platform, can benefit from OpenTelemetry integration by offering users advanced observability features similar to those available in CloudBees Jenkins. CloudBees Jenkins has successfully integrated OpenTelemetry to provide users with detailed pipeline telemetry, enabling better debugging, performance optimization, and system reliability. Harness can leverage OpenTelemetry to deliver similar benefits, enhancing its value proposition for DevOps teams. Proposed Features: Telemetry Data Collection: Enable Harness pipelines to collect telemetry data (traces, metrics, and logs) using OpenTelemetry SDKs. Support instrumentation of pipeline steps, workflows, and services. Distributed Tracing: Provide end-to-end tracing for workflows and deployments across distributed environments. Visualize the flow of requests and dependencies within the pipeline. Metrics Aggregation: Collect and aggregate pipeline performance metrics (e.g., execution time, resource utilization). Export metrics to popular monitoring tools like Prometheus, Grafana, or Datadog. Log Correlation: Correlate logs with traces for easier debugging and troubleshooting. Support integration with log management platforms like Elasticsearch or Splunk. Integration with Observability Tools: Allow seamless integration with third-party observability platforms (e.g., Jaeger, Zipkin, Honeycomb). Provide configuration options for exporting telemetry data to external systems. User Interface Enhancements: Add a dedicated observability dashboard in Harness to visualize traces, metrics, and logs. Offer customizable views for pipeline telemetry data. OpenTelemetry Configuration: Provide users with configuration options to enable/disable OpenTelemetry instrumentation. Allow customization of sampling rates, data retention policies, and export destinations. Benefits: Improved Debugging: Quickly identify bottlenecks, failures, and performance issues in pipelines. Reduce Mean Time to Resolution (MTTR) for incidents. Enhanced Performance Monitoring: Gain insights into pipeline execution times, resource usage, and efficiency. Optimize workflows for better performance and reliability. Standardized Observability: Leverage OpenTelemetry’s standardized approach to telemetry data collection and export. Ensure compatibility with a wide range of observability tools and platforms. Increased Adoption: Attract users who prioritize observability and monitoring in their CI/CD workflows. Position Harness as a competitive alternative to CloudBees Jenkins. Implementation Considerations: OpenTelemetry SDK Integration: Evaluate OpenTelemetry SDKs for compatibility with Harness architecture. Instrument pipeline steps and workflows to collect telemetry data. Data Export Options: Support multiple export formats (e.g., OTLP, JSON) for telemetry data. Ensure secure transmission of telemetry data to external systems. Performance Impact: Minimize the performance overhead of telemetry data collection. Optimize sampling rates to balance data granularity and system performance. User Documentation: Provide comprehensive documentation for configuring and using OpenTelemetry in Harness. Include examples and best practices for observability setup. Next Steps: Conduct a feasibility study to assess the technical requirements for OpenTelemetry integration. Collaborate with OpenTelemetry maintainers to ensure compatibility and adherence to standards. Develop a proof-of-concept (PoC) to demonstrate OpenTelemetry capabilities in Harness. Gather user feedback to refine the integration and prioritize features. Conclusion: Integrating OpenTelemetry into Harness will significantly enhance its observability capabilities, providing users with deeper insights into pipeline performance and system behavior. This feature will position Harness as a leading CI/CD platform with advanced monitoring and tracing capabilities, similar to CloudBees Jenkins.
