In my previous blog post, we saw how it’s possible to index some documents that we created by crawling our NetEye User Guide, then applying the ELSER model in Elasticsearch to create a bag of words for searching that takes into account the context of the various documents. Moreover, we also performed a simple query…
Read MoreIn 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…
Read MoreCybersecurity is a discipline that deals with protecting computer systems and digital data from attacks and security breaches. With the increasing use of technology and dependence on computer systems in everyday life, cybersecurity is becoming increasingly important. But what are the risks for those who don’t know how to protect themselves? Online security risks can…
Read MoreIn this post, I’ll describe a little Proof of Concept (PoC) that I developed to better understand Elasticsearch’s APM-Tracing and Real User Monitoring (RUM). We’ll see how we can use this technology to keep track of interactions between frontend and backend service(s), collect error logs centrally, and see where the bottlenecks are. I’ll put the…
Read MoreMost small open source documentation projects use Markdown to create their project documentation. After all, it has a minimalistic and thus easy-to-learn syntax, does all the basics well, renders very quickly (even quickly enough to create a real-time WYSIWYG viewer), and is almost universally supported across popular web platforms like GitHub. At some point, though,…
Read MoreWithin Internet provider companies, very often we are asked to calculate the amount of Internet bandwidth in order to bill any excess use of bandwidth to each customer. We decided to make this calculation completely customizable using NetEye together with the built-in tools Icinga2, InfluxDB and Grafana. Phase 1 Using an SNMP check, we measure…
