InfluxDB isn’t the best storage backend for NetData. It is much better to use VictoriaMetrics storage backend using the following config:

[backend]
        type = prometheus_remote_write
        destination = <victoria-metrics-host>:8428
        remote write URL path = /api/v1/write
        enabled = yes

VictoriaMetrics supports PromQL — much better query language than Flux from InfluxDB. See this article in order to feel the power of PromQL.

Additionally VictoriaMetrics uses less RAM, CPU and storage comparing to InfluxDB — see this and this article for details.
