OpenTelemetry is a promising observability solution that can help teams monitor their services' performance, but its adoption depends on understanding its capabilities and limitations. Nočnica will share her knowledge from the OpenTelemetry community to demonstrate instrumenting a demo application and learn what OpenTelemetry can do. The webinar will cover topics such as data collection architecture, Synthetic user testing and uptime monitoring with Checkly, and the history and status of development for OpenTelemetry. Nočnica, fresh off delivering a workshop at the CodeMash conference, will provide valuable insights from her 5 years in the community. The session will also explore known limitations and external monitor solutions like Checkly to complement OpenTelemetry's capabilities.
