OpenTelemetry automatic instrumentations greatly help with achieving a high baseline of observability for applications. But applying them in containerised environments still requires manual, error-prone intervention by users. LD_PRELOAD-based injection is an advanced technique that has been used by commercial vendors for a decade or more, is by now very well understood, and does not require access to the Kernel like eBPF does (which is a huge challenge in managed compute environments), or any increase in permissions other than what the host runtime has.

In this talk, we go in depth into how this magic works across various runtimes, and how it could benefit the OpenTelemetry community at large.
