A Simple Grafana Data Source for Outlier Detection (POC) – Part 1

In this article, I’d like to step through the development of a simple Proof of Concept (POC) Grafana data source with you where we retrieve data from an API, apply an outlier detection technique, and then visualize the end results in a dashboard. So… let’s begin! Note: All the code discussed in this blog post…

Bug Fixes for NetEye 4.28

We fixed a bug in the Alyvix module for which, in case of an Alyvix node where the Alyvix service was not working properly, a long waiting time was necessary before being able to determined its unreachable state. The waiting time was decreased and is now configurable. For NetEye 4.28 we updated the following packages:

Building a Dashboard in Kibana to Keep Track of Your Smart Ingest Pipeline

In a previous article, we used NetEye and Elasticsearch to train a machine learning model able to classify documents about some collected radar signals, separating them into two categories (good vs bad), starting from an existing dataset. Afterwards, we applied it to new incoming documents using an Ingest Pipeline and the Inference Processor. Taking as…

Bug Fixes for NetEye 4.25

We fixed a bug in El Proxy, for which the automatic verification breaks when the retention of Elasticsearch is applied. The bug fix introduced the concept of blockchain state history and this, if the retention of Elasticsearch already deleted some logs, will throw a warning during the first verification after the update. For NetEye 4.25…

Elasticsearch ML Models and Inference: Real-Time Classification

In a previous article, we explored the Machine Learning capabilities of Elasticsearch, which allowed us to apply anomaly detection techniques to our data, and helped us discover some really interesting facts as a result of our analysis. But can we take that idea even further? For instance, could we use data we’ve already collected to…

Bug Fixes for NetEye 4.24

We fixed a bug that prevented the installation of the perl-JSON-XS package, which can be required by external checks. We fixed two bugs in the Eventhandler. One bug causing a certificates verification error while using the GUI and another one causing the Eventhandler GUI to freeze when a particular race condition was encountered. For NetEye…
