+# Activity Log
+
+<!-- TODO: Image -->
+
+The activity log module provides a collective timeline of all data-changing actions taken within your project. It is accessed via the notifications tray of the sidebar. The page shares the filtering and search with the [Collection Page](/data-modeling/collections).
+

+
+Directus can only track the events which actually pass through its platform. Therefore, any changes made to the database
+directly are not tracked.

+
+Click on any item in the activity log and a side drawer will open, displaying its logged details. The following information
+is stored for each item:
+
+- **User** — The user that performed the action.
+- **Action** — The specific action taken (e.g., Create, Update, Delete, Comment, or Login).
+- **TimeStamp** — The timestamp of when the action was performed.
+- **IP Address** — The IP address of the device from which the action was performed.
+- **User Agent** — The description of the browser that was used to perform the action.
+- **Collection** — The Collection affected by the action.
+- **Item** — The ID of the item affected.
+- **Comment** — The comment left by the user (when applicable).

+## Filter by Activity

+
+In addition to the filter and display functionality inherited from the
+[Collection Page](/data-modeling/collections), you can also filter items by activity from the
+navigation bar.

+
+To ensure proper accountability, system collections are read only by design. However, users with an Admin role have
+the ability to reopen, view, and modify an item's values in activities from non-system collections (where the name does
+not begin with `directus_`).
