# Quest Log

## Overview

The **Quest Log** is a powerful diagnostic and transparency tool built into the FLECS WebApp. It enables users to monitor, log, and trace system activities in real-time and retrospectively.

It provides a comprehensive view of what is happening on the device, what actions have been triggered, which steps are currently running (even in parallel), and whether these operations have succeeded or failed.

Access to the Quest Log is simple: just click the dedicated **Quest Log icon in the top-right header of the FLECS WebApp**.
