Is there a way to show CPU and memory usage on a react-native app?

The React Native performance monitor is a tool that helps you understand the performance of your application by displaying real-time performance metrics, such as the frame rate and memory usage.

By default, the performance monitor does not display CPU or RAM usage. However, you can use the react-native-system-info package to get CPU and RAM usage information in your React Native application.

To use the react-native-system-info package, you will need to install it first:

npm install --save react-native-system-info

Then, you can use the getCPUUsage() and getTotalMemory() methods of the SystemInfo module to get the CPU and RAM usage, respectively. Here's an example of how you can use these methods:

import SystemInfo from 'react-native-system-info';

const cpuUsage = await SystemInfo.getCPUUsage();
const ramUsage = await SystemInfo.getTotalMemory();

You can then display the CPU and RAM usage information in your application using the performance monitor or any other method you prefer.
