In today's software landscape - in the cloud-native one in particular - observability has become a critical aspect of ensuring the performance, reliability, and security of applications. OpenTelemetry, a standard and OSS observability framework, provides a unified way to collect and export telemetry data from applications and services. This tutorial will guide participants through the process of using OpenTelemetry to instrument a simple application, collect metrics, traces, and logs, and send them to various backends for analysis. It covers the implementation and usage of OpenTelemetry into Python and Java-based applications. The exercises include: the instrumentation of a polyglot microservice application, auto vs. manual instrumentation, evaluating the collected traces, logs and metrics, configuring a collector, analysing the results in Jaeger and Prometheus. This tutorial is made for everyone seeking a pragmatic understanding of OpenTelemetry's immediate benefits.
