Monitoring began by using software agents to capture data from infrastructure, operating systems, and applications. These agents would collect metrics and events from these systems to understand the health of the underlying system and the applications. This is what infrastructure monitoring is today.

With microservices becoming popular, tracing is increasingly more important in debugging production software. In this post, we take you through a step by step guide on setting up Jaeger over Kubernetes with Cassandra storage.

In this article we are going to explain Jaeger integration with the OpenTelemetry collector, describe differences between these two and have a look at Kubernetes deployment via Jaeger Operator. OpenTelemetry collector is a vendor-agnostic service for receiving, processing and exporting telemetry data. In the Jaeger project we have decided to deprecate the Jaeger collector and migrate its functionality to an implementation based on OpenTelemetry collector.

In this article you will learn how to generate Jaeger model classes and gRPC services from protobuf definitions. The generated code can be used to write integrations or it can be used in tests to query tracing data from Jaeger-query service. This is the use case we are going to look at in more detail.
