Linux Tools: Monitoring & Troubleshooting Basics with Glances

Video is ready, Click Here to View ×

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:

  1. 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!

  2. 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.

  3. 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)

  4. I've very recently installed Netdata on my RPi3, it isn't really a troubleshooting tool but it does wonders if you have multiple PCs to manage.
    It can list eveything from IO per disk, CPU Time per user, interrupts, R/T per network interface, packets per second (in general, or udp and tcp), dropped packets, etc.

    It also features a 'alarm' system, so you will be notified when, for example, your disk has an ETA of 48h before becoming full, or when fail2ban (if installed!) detects too many attempts. Netdata doesn't need a server to collect data from netdata installs, each install is it's own server (avoids bottlenecks network-wise).

  5. Thanks Dave!. Just finished your Udemy "Hands on Linux Admin course". With your youtubes,the course, bsdnow youtubes and Michael Lucas books Ive learned more in the last few months than is the previous 20 years messing around with Linux on my own.Im using Freebsd now, I want to learn ZFS, jails, dtrace.I am liking the BSD approach to things. Look forward to more!.
