Thank you so much! I am currently working myself through the process of getting certified as a linux admin by my employer and your videos gave me a deeper understanding than the materials provided. So thank you very much and keep up the good work!
thank you very much, we never covered that topic at school and I'm going to have my LPIC exams next week, so I guess it's good to know since the uptime command is in the curriculum. I like your videos a lot!
I haven’t come across a book that explains this, if it even explains it at all, so thank you and the drawings were very helpful in visualising the process (bad word to use in this scenario but you get it!)
No, that's just a measure of the load averages for the past one minute, five minutes, and 15 minutes. It has nothing to do with how long the computer has been running.
finally, a video that explains the subject so detailed and clear. Thanks!!

Many thanks! I'm glad I could help, and I appreciate the kind words.
This is by far the best explanation, and might I say the only proper one on TH-cam. Thank you so much for clearing things out
You're welcome! I'm glad that I could help.
This was a really nice video, it's worth mention that tasks blocked on io also add up, especially no interruptible tasks
Many thanks! I appreciate the kind words and the suggestion.

Glad it was helpful!
Mr.Donnie. Thanks millions.
Thanks for explaining. I should have investigated this 20 years ago.
Now that explains why my system load goes >4 and the machine is fine :D That was a very nice and funny explanation, thanks!
Its really a wonderful crystal clear concept explanation .. thank you for sharing your knowledge with us ..

Glad it was helpful!
Thank you good tutorial, I'm completely understand Average CPU load now
Many thanks! I appreciate the kind words.
thank you for this info.
I would say - "Simply Brilliant" :)
thanks for explaining so clearly
Glad it was helpful!
This video would have helped me out in college!
thanks for the clarification
Thanks
Hello,
Thanks for this video!
A question: we've pretty powerful physical machine i.e. cpu cores: 24, ram: 128G. The load average is as:
13:57:27 up 292 days, 12:16, 2 users, load average: 31.50, 39.35, 44.05
13:59:26 up 292 days, 12:18, 2 users, load average: 33.17, 36.88, 42.54
I can understand that machine nicely utilised and having high load on it. Top commands show as below that there're still idle cpus on machine.
What is your opinion about this? What should be the actions from our end?

Taking that you have 24 cores, I don't think those load averages are very high. I guess your server should be perfectly fine.
Hi there! I agree with Hari. Those load averages look fine for a 24-core server.
❤️ I clearly my mind . Thank you so much. I was so much confused.
Many thanks! I appreciate the kind words.
Good explanation thank you.
Nice explaination
what command allows you to show only the last 15 minutes of the load average? and not the 1 minute and 5 minute
The only way I would know to do that would be to pipe the output of "uptime" into either awk or cut. For example:
uptime | cut -d" " -f 14
Does the 1 minute, 5 minute and 15 minute mean the time u have the computer on?
No, that's just a measure of the load averages for the past one minute, five minutes, and 15 minutes. It has nothing to do with how long the computer has been running.
@@beginlinuxguru7354 gracias!
Main Takeaway: When in doubt, choose Black.
are you using CPU rathers the GPU for BITCOIN(COIN) minning? Why not to use the GPU?
If I remember correctly, it was XMR mining, which only uses the CPU.
No sr, there's no mistery, not anymore. Thank you!
You are great when explaining linux, and soooo bad when drawing :d
I took drawing lessons from Picasso.
