🟠 Continuous Observability
Phase 4: Get a Bird’s Eye View, gain continuous Insight into your System
The “Continuous Observability” phase begins where traditional verification and validation alone are no longer sufficient: The developer continuously monitors the behavior of the embedded system throughout integration, testing, and operation. The goal is to identify errors, performance issues, and changes at an early stage and feed these insights back into the development process. Continuous Observability can be represented as an overarching feedback loop.
Distinction from “Debug & Trace”
We should clearly distinguish between these two phases:
Debug & Trace primarily answers: “Why is my system behaving this way right now?”
The developer investigates a specific problem in detail - typically during active development and debugging.
Continuous Observability, on the other hand, answers: “How does my system behave over time - and is anything changing?”
The focus here is not on a single debugging session, but on the continuous visibility of system behavior throughout its entire lifecycle.
This is what Continuous Observability does
Continuous Observability provides visibility into the behavior of embedded systems throughout the entire software lifecycle. Developers continuously collect and analyze logs, events, metrics, and runtime data, detect anomalies and performance regressions, and trace issues back to their root cause. The insights gained are directly incorporated into development, debugging, and verification - resulting in more reliable and continuously improved embedded software.
In a typical Embedded Project, these Steps are followed:
1️⃣
Collect relevant system data
- Record logs, events, and error messages
- Collect system states and operating parameters
- Monitor CPU, memory, and resource usage
- Collect communication and interface data
2️⃣
Monitor runtime behavior
- Monitor tasks, interrupts, and events
- Analyze timing and response times
- Track state changes
- Identify deviations from expected behavior
3️⃣
Analyze metrics and trends
- Compare performance metrics over extended periods
- Monitor memory usage and system load
- Evaluate the frequency of specific errors or events
- Detect gradual performance degradation
4️⃣
Detect anomalies and errors
- Identify unusual system states
- Track down sporadic and hard-to-reproduce errors
- Detect threshold violations
- Automatically report relevant events
5️⃣
Trace problems back to their root cause
- Correlate logs, trace data, and metrics
- Reconstruct the timing and context of an error
- Investigate the relationship between software changes and system behavior
- Perform root cause analysis
6️⃣
Compare versions and releases
- Compare behavior before and after software changes
- Identify performance regressions
- Evaluate the impact of new features
- Consolidate results from CI/CD, tests, and real-world system operations
7️⃣
Feed insights back into development
- Incorporate anomalies as new development or debugging tasks
- Fix errors and implement optimizations
- Supplement tests based on observed real-world error cases
- Improve the next software version based on the insights gained
