Sample dashboard not working

[nickabocker171]

I recently went through the iotstack setup and i think i have everything setup correctly except i noticed that grafana isnt showing anything on the imported dashboard. when looking at the data connections i noticed i was getting the following message when i clicked save& test
datasource is working. 0 measurements found

based on everythign else it appears to be working

I would first make sure the MQTT messages are getting to the broker using mqtt.fx or mqtt explorer.
if that's working then it's probably an issue with the telegraf configuration, either in the outputs.influxdb or the inputs.mqtt_consumer sections (topic, database name etc)
if that's ok, then try querying the influxdb using SQL commands
