Hands on with OpenTelemetry

Nočnica Mellifera - 2 years ago

In a few hours we'll instrument a demo application and see what OpenTelmetry can do. We'll also cover basic data filtering and compression. ### OpenTelemetry * History * What's in the project* Use cases * Status of development - Logs support is still growing, but you can send logs through the collector ### Collector Design* Most basic - direct from SDK to datastore, don't do this * Single collector* Collector -> collector * Daemonset in Kubernetes (I promise you don't need to know Kubernetes to follow this talk!)### Sample Application * Basic data emitter from the CLI * Auto-instrumentation with the language-appropriate SDK * Configuring data sends* A basic dashboard### Configuring the Collector * YAML config * restarting the collector ### OpenTelemetry Processors - config * batching - reducing sends * parsing - finding data early * crushing cardinality - getting the data you need * filtering - removing sensitive data * transforming with OTTL
