# Getting started with CPU Stats on Mbed OS

This guide reviews the steps required to get CPU statistics on Mbed OS platform.

Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).

## Import the example application

From the command-line, import the example:

```
mbed import mbed-os-example-cpu-stats
cd mbed-os-example-cpu-stats
```

### Now compile

Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:

```
mbed compile -m K64F -t ARM
```

Your PC may take a few minutes to compile your code. At the end, you see the following result:
