Get MAD! (Median Absolute Deviation)
The beautiful thing about using InfluxDB as a time series data store is that you get to have more control over your data, and the algorithms that detect anomalies.
In this talk by Developer Advocate, Anais Dotis-Georgiou, we'll learn:
- How Median Absolute Deviation algorithm works
- Numerical example of Median Absolute Deviation
- Identifying an anomalous series
- Using Flux to calculate the MAD and flag anomalies
- MAD on large datasets to assist in root cause analysis efforts
- How to contribute a User Defined Flux Package
