How do I model data in InfluxDB?
Modeling data in InfluxDB involves defining measurements, tags, and fields. Measurements are like tables, tags are indexed key-value pairs, and fields are the actual data values.
Can you give me an example of a measurement?
Sure! For instance, if you're tracking temperature, your measurement could be 'temperature_readings'.
What are tags and how do they differ from fields?
Tags are indexed and used for filtering, like 'location' or 'device_id'. Fields are not indexed and store actual data values, like the temperature reading itself.
How do I query data from InfluxDB?
You can use InfluxQL or Flux to query data. For example, to get the average temperature, you might use: SELECT MEAN(value) FROM temperature_readings WHERE time > now() - 1h
