How to Check Raspberry Pi Memory Usage in 4 Easy Steps

/0 Comments/in /by

Diagnosing and troubleshooting problems with your Raspberry Pi’s memory usage can sometimes be difficult and time consuming. Fortunately, learning how to check your Raspberry Pi’s memory usage is simple and fast with these four easy steps.

Check the memory usage using ‘free’ command.

One of the easiest ways to check your Raspberry Pi’s memory usage is to use the ‘free’ command. This command provides an overview of the system’s RAM and swap space, as well as information about shared memory and buffers. To run this command, open up a Terminal window on the Raspberry Pi and type in ‘free’ followed by pressing return. You will then be presented with a breakdown of how much RAM your Raspberry Pi has available.

Analyze RAM, GPU and CPU related tasks with ‘top’ command.

In addition to the ‘free’ command, you can use the ‘top’ command to diagnose detailed memory usage on your Raspberry Pi. By running ‘top’ in the Terminal window, you will get an overview of running processes related to RAM, GPU and CPU. This can help you identify tasks that may be using too much memory or other system resources and causing performance issues. To exit ‘top’, press CTRL+C on your keyboard.

Monitor memory usage in real time using ‘vmstat’ command.

If you want to monitor your Raspberry Pi memory usage in real time, use the ‘vmstat’ command. This command will display active processes with memories and will give you insight into which programs may be using more than their fair share of RAM. Type ‘vmstat 1’ to have vmstat output data every second. You can configure vmstat further by adding flags to the command such as ‘-m’, which shows detailed information about paging and swapping activities, or ‘-s’, which prints out a summary of memory usage on the system.

Monitor disk activity with ‘iostat’ command.

To get a more detailed overview of your Raspberry Pi memory usage and be able to monitor disk activity, use the ‘iostat’ command. This command shows read/write I/O operations with milliseconds latency, and can provide you with information about processes that are using large chunks of RAM or performing too many operations concurrently. Type ‘iostat 1’ to have iostat output data every second, or type ‘iostat -m’ to see detailed memory stats for active processes.

Log in to Your Raspberry Pi.

To check your Raspberry Pi memory usage, you will first need to log into your Raspberry Pi. If you are logging in via an SSH terminal, you can use the ‘ssh’ command followed by the IP address of your Raspberry Pi. If you logged in directly with a keyboard and mouse, simply enter the username and password of your Raspberry Pi. Once logged in, open up a terminal window using ‘Ctrl + Alt + T’ key combination to access the command line.

Low Raspberry Pi availability on the IoT market

Many companies have been impacted by the global chip shortage and supply chain issues, including electronics and automotive industries. This problem also touched the main producer of small board computers, Raspberry Pi. Company’s CEO, Eben Upton said that they had difficulty meeting demand for many of its products, but that it was taking steps to ensure devices were delivered despite supply constraints. 

“We’ve consistently been able to build around half a million of our single-board computers and Compute Module products each month. Where units do appear, bots often attempt to scalp stock which is then resold at higher prices elsewhere” said Upton. 

Sadly, for the average consumer who wants to build home projects or test software with Pi products, Raspberry Pi is prioritizing commercial and industrial customers. 

TECHBASE’s ModBerry with Compute Module 4 supply

As one of leading manufacturers of industrial solutions based on Raspberry Pi Compute Modules, TECHBASE is steadily fulfilling all the orders according to the schedule agreed with customers.

Sleep functionality for ModBerry 500 CM4 devices

ModBerry 500-CM4-PM series from TECHBASE company is an extended version of Raspberry Pi Compute Module 4 based devices for better power management in changing conditions of industrial applications. With the help of the integrated ESP32 module and the Arduino environment, the module can manage boot, sleep mode, or safe shutdown of the device in case of unexpected drop in the power network.

In the last few years developers marketed a wide range of ARM-based development boards, lacking in enhanced power management, especially sleep and wake up modes, commonly used in PC-grade computing. These boards are not adjusted for battery power supply, so it’s natural that sleep/wake functions should be implemented. In connection with the development of solutions based on Linux-SBC, key factor is adding sleep modes to any remote installation

ESP32 based addon module for Raspberry Pi

The TECHBASE sleep/wake add-on module can wake a device using a scheduler/timer that has built-in algorithms or can be programmed by the user. Modules based on ESP32-ROVER are used in Moduino X series boards. For Raspberry Pi, the ESP32 provides a lightweight and low-power solution. The program can also be woken up by external triggers, such as changes in input state. Various scenarios can be configured for sleep, shutdown, and wake functions, ensuring continuous operation of devices, the security of data, and the continuity of work in the event of a power outage.

Advanced power management solution

Most advanced configuration includes use of ESP32 module, known from the successful, lightweight Moduino X series, for extra logic for wake up / sleep scripts. This addon will allow the RaspberryPi-based ModBerry device to be woken up by the internal ESP32 controller. 

Moduino-ModBerry symbiosis allows a wide range of wake-up/sleep schedule customization, in order to perform best and save energy according to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.

Sleep mode with additional power backup

Additional power management option for ModBerry devices is sleep functionality enhanced with SuperCap UPS energy backup device. This solution allows programming scenarios including the execution of chosen actions, in order to save data, send a notification and restart/shutdown the controller after completion.

ModBerry 500-CM4-PM availability

The preliminary ModBerry 500-CM4-PM devices are available on request and delivery time will be specified by the Sales Dept. depending on the size of the project. Contact via email or Live Chat here: https://iiot-shop.com/
