Subcapability 04 of 05 · Platform Engineering

Observability

Three telemetry pillars instrumented via OpenTelemetry that turn a distributed system into a transparent box and reduce incident detection and resolution time from hours to minutes.

What is at stake

The system is degraded. The alert fired. But the on-call engineer does not know which service failed, which data is wrong and how many users are being impacted. The investigation starts from scratch, takes hours and the cost is already accumulating. Observability without correlation between metrics, logs and traces forces the team to work in the dark.

What it is, in practice

A distributed system without observability is an expensive black box. Each incident costs hours of investigation before reaching root cause. The board pays in broken SLAs and lost customers while the engineering team manually scans logs. By the time the problem reaches the support channel, the incident has already had a real cost: lost transaction, impacted user, escalation pressure. Recent research with operations teams shows that 82% of companies have incident recovery times exceeding one hour, and that mature observability programs reduce that time by up to 65%.

Frequently asked questions

What is the difference between monitoring and observability?

Monitoring answers questions you already formulated: "is the service up?" Observability answers questions you did not yet know you would need to ask: "why are 3% of user B's transactions failing on Monday mornings?" The difference lies in instrumenting all three pillars in a correlated way, allowing you to investigate new behavior without needing to add new metrics after the problem occurs.

Why use OpenTelemetry instead of the native instrumentation of the APM tool we already use?

Native tool instrumentation creates dependency: changing platforms requires re-instrumenting all code. OpenTelemetry separates telemetry collection from analysis. Code is instrumented once with the open standard. The analysis tool can change without touching instrumentation code. In an environment of rising observability costs, that portability has direct value in vendor negotiation.

How do you reduce rising observability costs without losing visibility?

With intelligent sampling and selective instrumentation. Not every trace needs to be recorded. Traces from successful low-risk requests can be sampled at 1% to 10%. Traces from errors and slow requests should be recorded in full. The combination reduces ingestion volume by 60% to 80% without losing visibility where it is needed.

What is the first step for an organization with no structured observability?

Instrument the three or four services that most impact revenue with all three correlated pillars. Do not start with the platform. Start with OpenTelemetry instrumentation of critical services and validate that metrics, traces and logs correlate in a real incident. With that evidence, expanding coverage has criteria and the platform investment has a foundation.

How does observability connect to SRE and SLOs?

SLOs define what is acceptable. Observability measures whether the system stays within what is acceptable. SLIs, the indicators that feed the SLO, are calculated from observability data: error rate, p99 latency, availability. Without instrumentation, the SLO stays on paper. Observability is what transforms an SLO from a document into a live contract with real data.
