VictoriaMetrics maps Influx data using the following rules:
* [`db` query arg](https://docs.influxdata.com/influxdb/v1.7/tools/api/#write-http-endpoint) is mapped into `db` label value.
* Field names are mapped to time series names prefixed with `{measurement}{separator}` value. `{separator}` equals to `.` by default, but can be changed with `-influxMeasurementFieldSeparator` command-line flag.
* Field names are mapped to time series names prefixed with `{measurement}{separator}` value.
`{separator}` equals to `.` by default, but can be changed with `-influxMeasurementFieldSeparator` command-line flag.
It is recommended setting it to `_` in order to be compatible with Prometheus, Promxy and `prometheus_client` plugin for Telegraf.
See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/79) for details.
See also `-influxSkipSingleField` command-line flag.
* Field values are mapped to time series values.
* Tags are mapped to Prometheus labels as-is.
