Installing rpi-monitor in Armbian 25.8 for Orange Pi Zero 3

Introduction

Rpi-monitor https://github.com/XavierBerger/RPi-Monitor is a very nice app for monitoring sbc (single board computers/ actually bigger computers as well) like RPi on a web. it give you a quick look at various system metrics cpu load, uptime, temperatures etc and more on a nice web page. and on top, makes nice time series graphs for the same, practically a dashboard.

install hostapd
```
apt install hostapd  
```
configure hostapd
/etc/hostapd/hostapd.conf

# the interface used by the AP
interface=wlan0

Building Armbian using Ubuntu (jammy) in a systemd-nspawn container

These are some steps for building armbian using Ubuntu (jammy) in a systemd-nspawn container. This is an alternative for building armbian from a Linux system (as like docker containers).

However this method requires the PREFER_DOCKER=no build flag as docker engines cannot be run within a systemd-nspawn container.

install
Start the systemd-nspawn container

	# This script runs ps_util.cpu_percent(interval=0.5) for each process to calc
	# the cpu utilization percentage
	# It does so concurrently as otherwise each calls sleeps 0.5 secs to sample the data
	# to run it faster use more threads in ThreadPoolExecutor(max_worker=x or
	# reduce the interval for cpu_percent(interval=x
	# To make readings more 'accurate' use a longer interval e.g. 1.0 for 1s.
