What Are Your Favorite Linux Tools for Performance Monitoring?
Asked by

Hey everyone! I'm still getting familiar with Linux, and I've realized there's a huge sea of knowledge out there. I'm diving into performance troubleshooting tools but it's a bit overwhelming with all the options available. I'm looking to monitor CPU, memory, Disk I/O, and networking in my system to identify bottlenecks. In Windows, it's straightforward with tools like Task Manager or Performance Monitor, but I'm finding it tricky to navigate the Linux landscape. I can use `htop` for CPU load averages, and I know about `atop` for historical data. However, there are so many tools like `vmstat`, `iostat`, and others out there. I'd love to hear about your go-to tools for performance monitoring, especially for Ubuntu and Red Hat, with a focus on command-line options if possible. Any recommendations would be greatly appreciated!

For those on GNOME, there's a great extension called **Astra Monitor** that sits in your panel. It’s super customizable, allowing you to choose what metrics to display. You can check it out here: [Astra Monitor](https://extensions.gnome.org/extension/6682/astra-monitor/). It's helped me keep track of performance easily!

I typically use **Mangohud** along with **Govarlay** when I'm gaming. Mangohud tracks everything like RAM, GPU, CPU usage, and frame rates. You can tweak what you want to see with Govarlay and just add `mangohud %command%` in your steam launch options once you have it set up. Also, I recommend **OCCT** as a stability tool to make sure everything's running smoothly, and you can grab it for free through Steam.

If you prefer a GUI, I highly recommend **KDE System Monitor**. It's packed with different gauges and you can customize it however you like. It might already be installed with KDE, but if not, you can get it with `sudo apt install plasma-systemmonitor`. Perfect for monitoring system performance!

For a general monitoring tool, I really like using **btop** in the terminal. It's user-friendly and provides a lot of information. If you're looking for a GUI, **Resources** is very similar to Windows' Task Manager and works great. For GPU monitoring, **nvtop** is a nice one; while it doesn't specifically highlight bottlenecks, it gives you lots of useful info that could definitely help you out.
