A beginner’s guide to my favorite linux system monitoring/troubleshooting tool: Glances. By the end of this video you’ll know the basics, and be able to quickly identify CPU, Memory, Disk/IO, and other issues on a machine.

If you still need to learn the basics of Linux before diving into monitoring, I’ve created a free Linux Sysadmin Course Playlist:

Really nice video Dave! When I first started using glances I switched back to htop because I didn’t know how to monitor each CPU thread individually. It turns out adding the -1 flag to glances provides CPU utilization at the thread level! I though it would be worth mentioning here in case there are any other potential converts who need this feature.

👍 Glance vs atop, which are the best? Honestly ive used atop and with log output you can discover historical problems, so don't forget it might useful also for security forensics… Imagine sending output to ELK and analize patterns of processes? It has a lot of possibilities with imagination

When you got to interrupts I kinda realized that maybe I should take my Linux skill down from intermediate to beginner on my resume lol

NICE.
I installed and work perfectly. But my distro only install Glances 2.3 with PSutil 3.4.2, will be nice if you tell how you install the last version.

Cool! Installs with pip – easy peasy…. and I must say… I can be proud of my baby… This is the first good look I've had at this Minty fresh build. I am new to Linux and in recovery from Windows now for about 2 years… Just coming out of my shell so to speak… Haha Look forward to learning more from you. Thank you very much 🙂

Looks good. Took a bit to install on my openSUSE 42.3 install but having installed the missing curses packages sorted that out. As for tools, the thing I've used would be Nagios Core which is good for monitoring systems around a network. Besides that and webmin which is more of a configuration tool, I can't really suggest much more.

Nice! Having the I/O and network info on top of the usual htop stuff makes it worth it. Thank you.

With this tool can I ever find out why wp-admin.php (WordPress login) is taking too long to load? I mean, the TTFB takes 1 or 2 minutes. I haven't been able to find out why neither in forums nor in Inspect Element tools. Server is Apache.

Very InTeReStiNg. This application is worth more than a glance 🙂 It's existence was news to me (no surprise). I paused the vid and installed it on a headless Pi3. I was daZzled. On a 27" screen I felt like I was in NASA SpaceX's control room. Thank you for your efforts. Cheers!

FYI Glances hails back from the old Unix days. This isn't a new tool, but damn is it still great

Started using htop after watching a tutoriaLinux video, will be checking Glances out too. I have personally found atop to be invaluable it's useful in interactive mode but the history mode is awesome, it allows you to see what was running when your server ran out of memory.

Thanks, alot Dave, appreciate these videos enhancing my QOL, would love to hear from Jeff and yourself about other programs you think are useful for smaller networking and pc management also larger programs out there that maybe someone would buy personally but in a corporation would be a good option ((podcast ideas)) Thanks for the podcast too (saved my sanity)
