I like the output of landscape-sysinfo on my Ubuntu servers. It looks like this:

  System information as of Wed Dec 28 13:51:17 UTC 2022

However, the landscape-common package isn’t available on Raspberry Pi OS.

To build:

sudo apt -y install git devscripts dh-python python3-distutils-extra gawk python3-twisted python3-configobj
git clone https://github.com/CanonicalLtd/landscape-client && cd landscape-client
env DEBEMAIL="Your Name <your@email.com>" env DEBUILD_OPTS="-us -uc" make package

Then to install:

sudo apt install python3-gdbm python3-netifaces bc lshw python3-twisted python3-configobj
sudo dpkg -i ../landscape-common_22.09+git6230-0ubuntu0_arm64.deb # Or other appropriate package name

(Note, for some reason the package is built to the .. directory!)

Amongst other things installing this package sets up a symbolic link from /etc/update-motd.d/50-landscape-sysinfo to /usr/share/landscape/landscape-sysinfo.wrapper which provides this kind of output.

Here’s sample output from a Raspberry Pi:
