System Info Commands

Kyle D. Harris — Thu, 15 Jan 2004 08:49:44 GMT

I need to find out the following about each of our servers and am not familiar with any commands to list this. If anybody can list some commands and state which each does that'd be greatly appreciated.
I need to find out:

RAM, Processors, disk space

Thanks!

df -h
will print the free/occupied space in human readable format for all mounted partitions

free
will show you the state of memory + swap
cat /proc/cpuinfo
will show some info regarding CPU/CPUs

df gives you the filesystems

du -k or du -sk (summary) will give you more detail.

top or gtop will give you a handle on many perofrmance and other measures. gtop has a graphical display for fileystems thats pretty nice.

Hi Kyle,

Alexander got it. I would add :
free -m will show your ram and swap in Megaoctets, easier to read.

df -h simplifies the reading, giving you low rounded value. df -H gives you upper rounded value, it may count on low space system.

No comment on cpuinfo, always astonished to see so many informations there !

hey guys, All i have left is to find out the Disk Space on each server.

The "gtop" command was not found. Top was found but was mostly about all the processes running and/or sleeping.

Whats a specific command to see the disk space on a server? Thanks for the help!

df -h shows the space left/occupied on mounted partitions

fdisk /dev/hda
then p to print -it'll show you the entire hard drive's space
if you have IDE , in other cases you'll have to find the drive (example /dev/sda for SCSI)

Hello,

if you are on SuSE hwinfo will give you this and much more information. You might want to write a script in case you need to check that on a regular basis.
