3. When a process is running, you can stop it by clicking the **stop** button.
4. Use this to search for tools. You can search by name and tool ID.
5. Here you can **clear your cache**. This is useful if you're experiencing performance issues or if you want to start fresh.

9. Additional option - read more below.
10. Here we have our **model metrics**. You can see the number of rows, columns and tools. You also see the current CPU and Memory utilization - these are updated every 2nd second. Read more about CPU, Memory and instances [here](/canvas/instances).
11. This is the **metrics chart**. It tracks CPU and memory usage in real-time and updates every 2nd second.
12. This is a **minimap** of the Canvas. It shows your current view and you can drag it around to change your view.
13. This is a **tool**. On top, you see the tool status (running, stopped, etc.). When you get closer to it, it switches to a setting wheel - you can click this to open the tool configuration. If you click on a tool, you run that particular tool. Below, you see the tool ID and annotations. You can edit the annotation by clicking on it (see more about documentation [here](/canvas/adding-documentation)).
