Hi all

Long time no see. I am getting busier in this 2015, but thanks God, I am given another opportunity to share knowledge.

This time I did it for my employer, IBM JTI Indonesia (June 22nd, 2015). The tutorial covers about the basic understanding of values displayed in /proc/meminfo in Linux, which generally tells you about memory statistics in Linux systems.

You can download it here. Please kindly left feedback here if you have any.

Ciao and regards,

Archieve of Online Linux discussion (/proc/meminfo, "top" basics etc..)

I did some online IRC tutorial regarding various Linux topic, here you read the brief description and the chat log too. Enjoy :)

- Everybody has ever seen the file /proc/meminfo, right? Great, but quite likely few of you really know the meaning of each fields there.

So, to help you understand those fields, I have given short lecture (and question/answer too) about it in #ubuntu-classroom in irc.freenode.net server. It was held in October 6th 2010, 21:00 GMT+7. Yeah, it is past already, but fortunately you can read the chat log here (note: the_hydra is me):

- Kinda "sequel" to the above session, I think discussing about "top" utility would be a nice discussion. So there you go, on January 27th 2011, 23:00 GMT+7 I did the lecture in #ubuntu-classroom of Freenode. The response was quite positive in my opinion. Few people ask about the meaning of each fields shown in "top".

Log can be read here.

Feel free to stop by and read it. Have feedback? Let me know at my usual contact addresses and I shall reply as soon as possible.

regards,

Mulyadi.
