Intermittent measurement rate through Grafana /

I'm experimenting with Grafana on both PC and RPi, and it can work well, no problems accessing anything from DBus. The issue I am seeing is that it will return data every few seconds for a period of anything from 10 mins - 40 mins and then nothing. The measurement rate drops off to nothing, I get a gap or 1 or more hours in the data and then it picks up again and off it goes.


There's no pattern emerging, so I am wondering what might be causing this. When it works, it works great. Network seems fine, database is running, CCGX is online, everything connected and I can see it producing data via the VRM without any issues.

I'd appreciate any thoughts on this.

Answering my own question - this was caused by the CCGX having insufficient processing power to cope with everything connected as well as run the MQTT service. I experimented first with a Raspberry Pi 4 which worked well, and now a Cerbo GX which runs everything with no problems at all.
