Have you ever wondered how the internet manages to translate the domain names you type into the browser into IP addresses that connect you to your desired websites? The answer lies in the Domain Name System (DNS), a complex network of servers and protocols that makes online communication possible. But with this complexity comes the need for DNS monitoring, which plays a crucial role in ensuring website availability, preventing security breaches, and optimizing network performance.

OpenTelemetry (OTel) is an open-source observability framework that provides a standardized way of collecting, processing, and exporting telemetry data (metrics, traces, and logs) from distributed systems. It was born by a merger between two previously separate observability projects, OpenCensus and OpenTracing, and it is currently maintained by the Cloud Native Computing Foundation (CNCF).

Let's say you log into your amazon or eBay account and start searching for a gift clothing. First you would filter out gender-specific collections, then you might fix a particular color or even a set of colors of your choice, and following that, you can fix a price range.

But ideally speaking, you won't find a native logging solution embedded in Kubernetes.
