OpenTelemetry (OTel)

OpenTelemetry, also known as OTel, is a tool for instrumenting applications. It provides a vendor-agnostic standard for traces, metrics, and logs. The OTel Collector can be deployed as a sidecar or daemonset to gather telemetry data, process it (batching, filtering), and export it to various backends (Jaeger, Prometheus, Azure Monitor), without changing application code.
