N/A values on Geth node Raspberry Pi

[pd1983]

Dear Developer;

i have installed and fully synced my raspberry pi 4 eth node from this build;

https://ethereum.org/fr/developers/tutorials/run-node-raspberry-pi/

it comes with prometheus app. I'm importing your following application into prometheus;

https://github.com/hunterlong/gethexporter

when i visit the dashboard all values comes with N/A values. What should i do to use your application? Just installed docker and runned the the commandline code. It came with hunterlog / getexplorer not found error.

thank you!
