The previous post introduced OpenTelemetry and the OpenTelemetry collector (aka otel-collector) which is acting as gateway to the backends persisting emitted log, metrics, and trace data.

With this post we have a more detailed look at the collector’s configuration and how it connects to the various databases

As applications and architectures become increasingly complex, monitoring application health is more critical than ever. Developers, support teams, and site reliability engineers need real-time insights into performance metrics, logs, and execution traces to ensure smooth operations.

Traditionally, achieving this required integrating multiple frameworks and tools for data collection, analysis, and visualization—often leading to fragmented solutions.
