Telemetry and observability

With the evolution of traditional monolithic architectures towards distributed loosely coupled microservice architectures, the need for detailed high-quality telemetry quickly became apparent. Before elaborating any further, let’s first define what Telemetry is in the context of IT infrastructure.

Telemetry

Refers to monitoring and collection of data about system performance for analysis that helps identify issues. Telemetry is a broad term for logs, metrics, and traces that are also known as telemetry types or signals.

With Cloud Native applications being distributed by design, the ability to track and trace all communication between the parts plays a major role for troubleshooting, finding bottlenecks and providing insights on how application performs.

All three telemetry signals (logs, metrics and traces) help us to better understand the state of the application and infrastructure at any given point of time and take a corrective action...
