Observability answers the question monitoring cannot: why the system ended up in its current state. This post explains what observability is, how it differs from monitoring, and where OpenTelemetry came from and why it became the de facto standard — for full-stack developers who want a systematic understanding of the concepts and ecosystem.
How traces, metrics, and logs are each produced and how they relate to each other is the core of understanding OpenTelemetry. This post covers spans and context propagation, metric aggregation and temporality, log correlation, and how the SDK and Collector divide the data path.
An observability solution consists of three layers: production, collection, and analysis. This post covers OpenTelemetry
