Panchanan Panigrahi has a nice overview of many parts of OpenTelemetry. He defines it:
Observability helps us understand what’s happening inside our systems by looking at the data they produce. OpenTelemetry is a toolkit that helps collect this data, like traces, metrics, and logs, making it easier to monitor our applications. With OpenTelemetry, we can track how our software behaves, diagnose issues, and improve performance.
