## Telemetry Overview Window

See Also

The Telemetry Overview window displays smaller versions of the graphs that are presented in the VM Telemetry window. The window displays high-level data on thread activity and memory heap and garbage collection in the VM. The VM Telemetry window is typically located below the editing area and sharing the space with the Output window

You open the Telemetry Overview window by choosing Window > Profiling > Telemetry Overview from the main menu.

The VM Telemetry tab contains three graphs displaying data on the following processes:

- Threads (Statistics). The Threads graph displays the total number of threads in the profiled application JVM. You can place your cursor over the graph to display a tooltip with the current and maximum number of threads.
- Memory (Heap). The Memory (Heap) graph displays the total and used size. These are the figures that a Java application can obtain using the `java.lang.Runtime.totalMemory()` and `java.lang.Runtime.freeMemory()` calls.
- Memory (GC). The Memory (GC) graph displays the relative time spent in garbage collection and the number of surviving generations.
