FWIW, one thing I noticed today is that you can have common schema for
multiple MQTT topics, so even if telegraf puts everything in a
mqtt_consumer database within influxdb by default, you can easily get the
value you want in grafana by specifying which topic to pull it from.
So theoretically if you had a bunch of sensors with a schema ala {
"sensorID": 12345, "degF": 72.3 } publishing to MQTT, as long as each
sensor wrote to a different topic (perhaps sensor/12345 for illustration)
you could get a nice multi-sensor multi-topic graph in grafana all from the
same telegraf-ingested influxdb.
