Why not have the InfluxDB collector understand _value?

[philomory]

This may not be the correct place for this, but I didn't see any mention anywhere of a discussion list or a Slack channel: is there are particular reason to require each Flux query to manually rename the _value column to metricvalue, rather than just having the adapter read the _value column directly? I'm having a hard time thinking of a use case where this behavior is desirable.

(To be clear, the adapter functions perfectly well either way, I'm just curious regarding the design intent behind it)

@affo contributed the influxDB support. Maybe you remember the reason why it had to be done that way? I see this comment in the example:

Rename "_value" to "metricvalue" for letting the metrics server properly unmarshal the result.

But I don't know if there would be a way around it.
