Should DR and frequency be handled as SNR and RSSI (_measurement) in InfluxDB2 integration?

[andryyy]

Hi,

referring to

chirpstack-application-server/internal/integration/influxdb/influxdb.go

Lines 200 to 206 in b4ddcf0

	tags := map[string]string{
	"application_name": pl.ApplicationName,
	"device_name": pl.DeviceName,
	"dev_eui": devEUI.String(),
	"dr": strconv.FormatInt(int64(pl.Dr), 10),
	"frequency": strconv.FormatInt(int64(pl.GetTxInfo().GetFrequency()), 10),
	}

DR and frequency are handled as tags and therefore inserted as string values into InfluxDB2:

It would be nice to query InfluxDB2 for measurements on DR or frequency, too. It is possible to use keyValues in Flux, drop all other measurements and convert the string to an int, but that's pretty heavy on resources.

I use it to create alerts on drops to lower DRs. Frequency is probably less interesting and just interesting to see. :-)

What do you think about that?
