OpenTelemetry (OTel) is a CNCF project that provides a standard way to send application trace information. Traces become important as you begin to build a distributed system as you need to be able to trace a request and response through multiple systems. OTel provides a vendor-agnostic instrumentation library that can be used to forward trace data to a backend to visualize or analyze the data.
