We’re bringing OpenTelemetry to R. As a Posit-wide initiative across our open source packages, we’ve instrumented some of the most widely-used R packages for production workloads – Shiny , plumber2 , mirai , httr2 , ellmer , knitr , testthat and DBI . You can add observability to your R applications with no code changes: set a few environment variables and you get traces, logs, and metrics flowing to the backend of your choice.
