 Both OpenTelemetry and Jaeger are open-source projects incubated under Cloud Native Computing Foundation. OpenTelemetry and Jaeger enable application owners to set up monitoring and observability to measure application performance. But their solutions are meant for different problems. While OpenTelemetry helps generate telemetry data, Jaeger is a distributed tracing tool.

+**What is Observability?**
 In control theory, the term “observability” states that a system is observable if the internal states of the system can be determined by looking at its inputs and outputs.
 For distributed software systems, observability means how well we are able to troubleshoot our systems for performance issues with collected data from the system.

 Instrumenting every aspect of your application and infrastructure is the first critical step to keeping a check on application performance. OpenTelemetry can take care of the entire instrumentation layer as it supports multiple programming languages and technologies.
 
-The next step is about choosing a backend analysis tool. Jaeger supports data formats of OpenTelemetry. But Jaeger is limited in terms of its UI and does only distributed tracing. For a robust monitoring and observability framework, you need a unified UI for both metrics and traces.
