To return relevant search results and to create Kibana dashboards that allow them to analyse data and give the customers what they want. But there are some cases where the customer is always wrong, and where the last thing you want to do is give a site visitor what he wants. Welcome to the world of forensics, compliance and fraud detection.

By even casual observation, you’ll likely have noticed that there are several IP address ranges that are special, including: Anybody can use these “private” ranges for anything they like. But there are actually several other special ranges that have other special purposes. In this article, I’ll explain what they are and the purpose they serve. This is the “loopback” range. These are addresses that are assumed to be on the same device that’s sending the packet.

I have a beef with companies that don’t expose nearly everything their product can do with an API. I get anxious wondering, “why can I only do some of the things via the API? How is this sausage made?” Sure, there are plenty of examples of endpoints that shouldn’t be exposed, such as changing passwords probably should be kept private. Regardless, there are tons of examples of products that I can type in a field in the UI, but that field isn’t available in the API.

Ingesting various events and documents into Elasticsearch is great for detailed analysis but when it comes to the common need to analyze data from a higher level, we need to aggregate the individual event data for more interesting insights. This is where Elasticsearch Data Frames come in. Aggregation queries do a lot of this heavy lifting, but sometimes we need to prebake the aggregations for better performance and more options for analysis and machine learning.

In this guide, we will use Ansible as a Deployment tool in a Continuous Integration/Continuous Deployment process using Jenkins Job. In the world of CI/CD process, Jenkins is a popular tool for provisioning development/production environments as well as application deployment through pipeline flow.
