Observability
Software Engineering · Mechatronics & Robotics · Last updated: July 30, 2026 · How this entry was written
Definition: Observability is the ability to infer the internal state of a system from its external outputs, such as logs, metrics, and traces. It enables engineers to understand and troubleshoot complex distributed systems without additional instrumentation.
Example in context
“Improving observability in our microservices architecture helped us quickly identify the root cause of the performance degradation.”
“Mikro hizmet mimarimizde gözlemlenebilirliği iyileştirmek, performans düşüşünün temel nedenini hızlıca belirlememize yardımcı oldu.”
Where engineers use it
Observability is vital for cloud-native applications where dependencies are complex. Engineers use tools like Prometheus and Jaeger to collect data and reason about system behavior, especially during incidents.
Synonyms: o11y
Antonyms: blindness
In Mechatronics & Robotics
The structural property that all internal states of a system can be reconstructed within finite time from measurements of its outputs. Without it, an estimator cannot recover the hidden variables a controller needs.
“Adding a second encoder restored observability, so the estimator could finally infer shaft torsion from the two position measurements.”
Practice: can you use “Observability” at work?
During an outage, the team cannot understand why requests are failing. They ask you: 'How can observability help us debug this faster?' Explain.
