Server Spec Analysis

Here are some Useful tools to check the specs of a server¶

CPU¶

lscpu

You can see the output below when the command is used on a server. Usually this would contain more information that this.

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                2
On-line CPU(s) list:   0,1
Thread(s) per core:    2
Core(s) per socket:    1

You can see that this server has 2 cpu cores by looking at the CPU(s). It's rare that the average physical cpu would only have 2 cores so we can assume this is all virtual.

RAM¶

We can check the ram by using either free -m or free -g

Here is the output for both

free -m

simon@simon free -m
              total        used        free      shared  buff/cache   available
Mem:           7971        7173         189         267         608         273
Swap:          8079        3543        4536

simon@simon free -g
              total        used        free      shared  buff/cache   available
Mem:              7           6           0           0           0           0
Swap:             7           3           4

free -m is more useful if you want to be accurate.

Disc Space¶

Disc space can be found by simply using df -h. Here is some example output

simon@simon df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        3.9G     0  3.9G   0% /dev
tmpfs           3.9G  726M  3.2G  19% /dev/shm
tmpfs           3.9G  2.0M  3.9G   1% /run
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/dm-3       108G   93G   11G  90% /
tmpfs           3.9G  1.9M  3.9G   1% /tmp

tmpfs           798M  108K  798M   1% /run/user/1000
