Hi,

The anomaly detection features in x-pack look awesome. I was wondering, though - if my data has a dimension (let's say country) with a cardinality of 150 - do I have to make 150 separate metrics to see anomalies for individual countries, or can I create one metric, and let the software surface a particular country with an anomaly?

thanks,  
imran

There is a lot of useful examples and links available in [this GitHub repo](https://github.com/elastic/examples/tree/master/Machine%20Learning). Based on your description it sounds like you may want to configure [a multi-metric job](https://www.elastic.co/videos/machine-learning-tutorial-creating-a-multi-metric-job), so that may be a good starting point.
