Microservices have grown to become one of the most optimal alternatives to monoliths. However, just building your app and releasing it to the public isn’t everything. Monitoring microservices is as important as building and releasing them. You need to maintain it to resolve issues that may occur and also introduce new features from time to time.

Software applications have become crucial for business growth and success in today's world. However, as businesses become increasingly competitive, the necessity to provide top-notch software applications is also increasing. Additionally, as organisations gravitate towards developing extensive, feature-rich applications, they are witnessing an increase in software complexity – that can often cause things to get out of hand very quickly.

OpenTelemetry is a free and open-source software initiative with the objective of supplying software developers with the means to create distributed systems. OpenTelemetry was developed by engineers at Google, and developers have the ability to utilize it to create a standard foundation for the construction of distributed systems. The goal is to enable developers to write code once and then deploy it in any location of their choosing.

In today’s digital world, users expect to have a seamless experience in their day-to-day applications. To achieve such reliability and stability in our application, information about the health and performance of an application has become necessary for developers to gain insights and fix bottlenecks to provide a seamless user experience. One of the best ways to gain such insights into an application is to use a monitoring system.

Telemetry data is a powerful tool for understanding the behavior of complex systems. OpenTelemetry provides a platform-agnostic, open-source way to collect, process, and store telemetry data. This post explores the OpenTelemetry collector architecture, specifically focusing on the Collectors component. We'll look at how collectors work and how they can be used to process telemetry data from any system or application. We'll also discuss some benefits of using OpenTelemetry for your telemetry needs.

The OpenTelemetry Collector is an application written in Go. The GitHub readme does a great job of describing it: So the OpenTelemetry collector is a Go binary that does exactly what its name implies: it collects data and sends it to a back-end. But there’s a lot of functionality that lies in between. What a neat service! A local destination for data that handles the final sending of Open Telemetry information to your back end.
