Prometheus will check these text pages, or "targets," at a specified interval, looking for updates to the data. In a nutshell, instrumenting the application for Prometheus requires taking the data from the sensor, labeling it, and serving it as text over HTTP so that Prometheus can find and store the data. This is where Prometheus shines as a time-series database with its own query language and graph capabilities. That is good for checking the data manually for each moment, but it would be far more useful for me to gather and store the data to examine it historically. ![]() In my previous article about using a Raspberry Pi Zero and DHT22 to collect temperature and humidity data, I showed how to write a Python script to gather the data and print it to the screen. ![]() It is used at huge scale by large enterprise organizations, but it is equally at home, well, at home, collecting data for hobbyist projects. In my job as a site reliability engineer running OpenShift Dedicated clusters for Red Hat, Prometheus is the core of a robust monitoring and alerting system for all of our clusters, operators, and applications. Prometheus is frequently used to gather data from container orchestration clusters such as Kubernetes and OpenShift. I've written about setting up Prometheus locally at home. Prometheus is an open source monitoring and alerting system that gathers metrics and provides a powerful query language for exploring data.

Ubuntu user needs to firstly press Ctrl+Alt+T on keyboard to open terminal. ![]() Method 1: Install the extension via browser Which means, you may install and run it in Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Fedora 34/35/36, and other Linux (e.g., Debian, Arch, Manjaro) with GNOME. The extension supports GNOME from version 3.18 to the current 42. In which, you may configure the refresh interval, indicator position, as well as toggle display sensors. There are as well bottom buttons to quickly launch system monitor utility and open the extension “Preferences” dialog. And, user may click on menu option to select which to display on panel. It’s a Gnome Shell extension that can display following information on your system tray area:Ī drop-down menu is available to take a glimpse of all available data. Want to display your computer’s temperature, voltage, fan speed, memory usage, and other system resources usage in top panel? Vitals is a good choice for Ubuntu, Fedora Workstation, and other Linux with GNOME desktop.
