In this post, we learn how to use the reduce(), findColumn(), and findRecord() Flux functions to perform custom aggregations with InfluxDB. This TL;DR assumes that you have either registered for an InfluxDB Cloud account – registering for a free account …
Machine learning — the practice of writing algorithms that improve automatically through experience — has become a buzzword nowadays that connotes to something otherworldly and on the bleeding edge of technology. I’m here to tell you while that may be …

Performance has been a top user concern and an area of investment for InfluxDB Cloud since launching a year ago. The theme of our recent performance push is aggregations; we took a vertical slice from backend platform to front-end user …
In this post, we share how to use the array.from() function to construct a table from an array of records with Flux. Flux is InfluxData’s scripting and functional query language. This TL;DR assumes that you have either registered for a …

In this post, we share a way to generate a table with Flux. Q: I want to perform a task that executes a join() but I don’t always have data for one of the input tables. How can I create …
In this tutorial, we’ll use the BIRCH (balanced iterative reducing and clustering using hierarchies) algorithm from scikit-learn with the ADTK (Anomaly Detection Tool Kit) package to detect anomalous CPU behavior. We’ll use the InfluxDB 2.0 Python Client to query our …
When you want to spot containers, virtual machines (VMs), servers, or sensors that are behaving differently from others, you can use the Median Absolute Deviation (MAD) algorithm to identify when a time series is “deviating from the pack”. In this …
