Does Grafana server + influxDB + ChirpStack Gateway OS full runs on same Raspberry pi that RAK2245 mounted gateway? As you know latest raspberry pi 4 have 8gb ram. I will only monitor about 20-30 nodes. Do I need to use docker or should I install packages directly on raspian OS ? Will sdcard wear out, if I boot OS from sdcard but install services on HDD and run from there ?
