openUBMC Observability: Full Insight into the System for a New BMC Vision

As digital transformation surges forward, system complexities escalate continuously. The efficient monitoring and management of distributed systems have become a key challenge. As a bridge between hardware and software, the baseboard management controller (BMC) is responsible for device management, monitoring, and maintenance. openUBMC 25.06 introduces the Observability component to provide complete observability capabilities based on openTelemetry, enabling developers to clearly understand system status, quickly locate issues, and optimize system performance.

This article explores the advantages, value, and prospects of openUBMC Observability. We look forward to your participation in the capability development of openUBMC Observability.

Advantages

1. Unified Data Collection and Management

openUBMC uses openTelemetry to implement unified collection and management of metrics, logs, and traces. All data, including hardware status, system performance, and software status, is integrated and reported to openUBMC to ensure data integrity and consistency.

• Standard programming APIs
  openUBMC encapsulates and provides application programming interfaces (APIs) based on openTelemetry to simplify data collection. Developers can easily integrate telemetry data into the BMC system through simple API calls.
• Standard data formats
  The unified telemetry framework defines compatible and consistent formats for metrics, logs, and traces, facilitating subsequent data processing and analysis.
• Standard transmission protocols
  openTelemetry Protocol (OTLP) is used, supporting both gRPC and HTTP/JSON. gRPC is applicable to high-performance scenarios for efficient data transfer. HTTP/JSON provides wide compatibility, facilitating integration with existing systems and tools.

2. Seamless Integration with Mainstream Tools

openTelemetry Collector allows openUBMC Observability to seamlessly integrate with tools such as Prometheus, Zipkin, Jaeger, and Elasticsearch, Logstash, and Kibana (ELK). In this way, powerful data visualization and analysis capabilities are provided to help users better understand and optimize system performance.

• Data collection and processing openTelemetry Collector supports multiple data formats and protocols, and can flexibly process telemetry data (metrics, logs, and traces) from various data sources.
• Data conversion and export openTelemetry Collector can convert collected data and export it to different target systems, such as Prometheus, Grafana, and Jaeger. This enables the observability data from the BMC to be simultaneously used by multiple tools, thereby improving data utilization.

3. Powerful Distributed Tracing Capability

With the visualized analysis capability of platforms such as Zipkin, openUBMC can clearly display the complete call paths. Developers can easily trace every operation from hardware to software, and thus quickly locate performance bottlenecks and faults.

4. High Scalability and Flexibility

openUBMC provides APIs to support highly scalable observability. Developers can customize data collection and processing logic as required to meet observation requirements in different scenarios.

Value

Data-driven benefits: By monitoring the hardware and software status in real time, openUBMC aggregates and analyzes data to accurately identify performance bottlenecks and potential risks. With targeted data collection, it identifies and locates anomalies early in the development phase, effectively preventing failures and enhancing overall system stability and reliability.

During fault locating, clear call traces and accurate performance data enable developers to quickly define the fault scope, accurately trace the root cause, and significantly shorten the fault rectification time. The following issues were identified using the observability component during the R&D of the 25.06 version:

• Flash log flooding
  By monitoring the flash write volume and analyzing its growth trend, openUBMC detected and prevented flash lifespan degradation caused by excessive writes.
  
  
• Hardware access failure By monitoring hardware access metrics and filtering access errors, openUBMC detected and prevented faulty hardware through the error growth trend analysis.
  
  
• Improper CSR configuration
  By monitoring hardware access metrics and analyzing the collected data, openUBMC detected and prevented improper or invalid device access configurations in the CSR, optimizing hardware access cycles and improving overall BMC performance.
