# Logging records {#data-logging}

Pipeline trace records store runtime events. They are intended for debugging,
not as permanent analytics storage.

Typical trace events include:

-   step started;
-   step finished;
-   LLM request;
-   LLM response;
-   retrieval request;
-   retrieval result;
-   error.

Production installations should limit trace retention and mask sensitive data.
