Using Flux to Write Data Out to SQL Data Stores
As discussed in multi-data source Flux, Flux can now get data out of RDBMs with SQL.from() and use it to perform deeper analysis. In many cases, results from crunching data lend themselves naturally to time series storage. In others, the results are...
Hiding Complexity with Custom Functions: Calculating Heat Index
Have you ever watched the local weather or The Weather Channel and heard them announce the temperature, and then the “Heat Index”? Or how hot it feels outside? At least here in the United States, and especially in the South, it’s...
How to Output Data from Flux to MQTT Natively
Writing data from InfluxDB to MQTT using Flux I started using the Open Source (OSS) version of InfluxDB v2.0 very early on in the Alpha releases. Even in the early releases, I was very enamored with the way things were shaping...
Use Flux to Group, Shape, and Analyze Your Time Series Data
Flux is a programming language designed from the ground up for time series analysis. Traditionally, grouping, shaping, and performing mathematical operations across large dynamic time series datasets is cumbersome. Flux’s goal is to make it working with these datasets much more...

Getting Started with InfluxDB 2.0: Scraping Metrics, Running Telegraf, Querying Data, and Writing Data
Now that we’ve released InfluxDB 2.0 Alpha, you’re probably curious to try it but might not know where to start. This post will guide you through the process of getting it running locally on your machine. By the end of this...
Practical Uses of Cross-Measurement Math in Flux
I’ve been spending a lot of time lately with the 2.0 Alpha releases and I’m here to tell you: some of the new things coming are really, really cool! Especially for IoT. The one I’ve been using lately has been the...
InfluxDB: Reorganizing Data with the Pivot Function in Flux
If you’ve been following along with my Flux journey as I implement Flux queries with Rails and GraphQL, you’ll know that I’ve been using train data when implementing various functions in Flux. In order for the GraphQL gem in my Rails...
Using GraphQL with InfluxDB and Flux
In a previous post, we showed you how to make Flux queries in a Rails app. In this post, we’ll extend that knowledge to use GraphQL in a Rails app which leverages the power of Flux to query InfluxDB. This allows...
