OpenTelemetry is a vendor-agnostic instrumentation library. In this article, let's explore how to auto-instrument a Tomcat Java application using OpenTelemetry Java JAR agent.
OpenTelemetry emerged as a single project after the merging of OpenCensus(from Google) and OpenTracing(from Uber) into a single project. The project aims to make telemetry data(logs, metrics, and traces) a built-in feature of cloud-native software applications.
OpenTelemetry auto instrumentation libraries are the best option for someone who doesn't want to modify their application code for generating telemetry data(logs, metrics, and traces). In this article, let's see what options does OpenTelemetry provides for auto-instrumenting your Java apps.
