c'e' una versione di prometheus per raspberry (quindi armv7 e anche armv6):
scaricabile da:
https://github.com/prometheus/prometheus/releasesSe il tuo sistema embedded usa systemd, la procedura di installazione manuale e' (per armv7- raspberr):
cd /home/pi
wget https://github.com/prometheus/prometheus/releases/download/v2.26.0/prometheus-2.26.0.linux-armv7.tar.gz
tar xfz prometheus-2.26.0.linux-armv7.tar.gz
mv prometheus-2.26.0.linux-armv7/ prometheus/
e relativo servizio systemd in /etc/systemd/system/prometheus.service

Una volta avviato il servizio (che usera' di default il file di config su /home/pi/prometheus/prometheus.yml), avrai la gui di prometheus su http://<IP>:9090 da dove potrai eseguire query e monitorare lo stato del servizio
La stessa procedura puo' essere seguita per grafana (binari armv6 e v7 ):
wget https://dl.grafana.com/oss/release/grafana-7.5.4.linux-arm64.tar.gz
tar -zxvf grafana-7.5.4.linux-arm64.tar.gz
E poi puoi lanciare direttamente grafana-server o crearti un servizio copiando i file di configurazione in /etc ..
