Check Server Configuration - Memory, Hard Disc, Processor in Ubuntu Linux

In Linux Ubuntu you do not have any GUI mode to display the RAM detail and Hard Disk details. So you need the commands to view the server status in Ubuntu.

1. View RAM Details

You can view RAM details if different units like KB, MB, GB etc. Default is KB.

free

Output:

  total used  free shared   buff/cache available
Mem:8173808114806447278688568822978766591952
Swap:104857201048572   


View in MB:

free -m

Output:

  total used  free shared   buff/cache available
Mem:7982109646418322446461
Swap:102301023   

 

Display RAM details with Units:

free -h

Output:

  total used  free shared   buff/cache available
Mem:7.8G1.0G4.6G83M2.2G6.3G
Swap:1.0G0B1.0G   

 

2. View Hard Disc Details

You can view RAM details if different units like KB, MB, GB or with unit. Default is KB.

df -h

Output:

FilesystemSizeUsedAvailUse%Mounted on
udev3.9G03.9G0%/dev
tmpfs799M8.6M790M2%/run
/dev/xvda149G27G23G54%/
tmpfs3.9G03.9G0%/dev/shm
tmpfs5.0M05.0M0%/run/lock

You can view Total value by using:

df -h --total

 

To check hard disk memory used by and directory:

du -hs /path/to/directory

Output:

21G              /var/www/

 

3. View Processor Details

cpuinfo provides all the information about the CPUs.

cat /proc/cpuinfo
