You can view high-level data on thread activity and memory heap and garbage collection in the VM Telemetry window. The VM Telemetry window is typically visible in the main Editor window.

To open the VM Telemetry window, do one of the following during a profiling session:

- Choose Window > Profiling > VM Telemetry from the main menu.
- Click VM Telemetry ( ) in the Profiler window.

VM Telemetry results are displayed in the following tabs:

- Memory (Heap). This tab displays the total size and used size of the heap.
- Memory (GC). This tab displays the relative time spent in garbage collection and the number of surviving generations.
- Threads/Loaded Classes. This tab displays the total number of threads in the profiled application JVM.

In each of the tabs, you can place your cursor over the graph to invoke a tooltip that displays more detailed data.

The toolbar of the VM Telemetry window contains the following items:

Button | Function
--- | ---
| Save Current View. Click this to save an image of the current results as a `.png` file.
| Zoom In. Click this to increase the detail of the graph.
| Zoom Out. Click this to decreases the detail of the graph.
| Scale-to-Fit. Click this to modify the display of data so that the entire graph fits in the window.

You can select a region of the graph with your mouse to see that region in greater detail.
