How to set up percolator to return when an aggregation value hits a certain threshold? Effectively monitoring security across a large organization is a non-trivial task faced everyday by all sorts of organizations.The speed, scalability and flexibility of the Elastic stack can play as a great asset when trying to get visibility and proactively monitoring large amounts of data. Note that we could have multiple detections from different hosts, however for the purpose of this blog post we limit ourselves to detecting and reporting only the first one in the list. You could contrive an anomaly that you want to detect by allowing the ML job to learn for a while, then artificially created a port scan from a single device and see if the anomaly is reported as you expect.
