APIs power complex and modern applications and in doing so they’ve also become a challenge to observe, monitor, and analyze. Even the apps we rely on daily consists of numerous services, each glued together by dedicated APIs that interact with one another in intricate ways. In today’s market, you have to make sure that API complexity doesn’t hurt the visibility you need to possess into your product.

In this blog post, we will explore how organizations can leverage Kong and OpenTelemetry to establish and monitor Service Level Objectives (SLOs) and manage error budgets more effectively. By tracking performance metrics and error rates against predefined thresholds, teams can prioritize their work based on the impact on user experience and business objectives. This approach helps optimize the balance between innovation and reliability.

N|Solid Runtime, the OSS runtime that powers N|Solid Pro, is an innovative, lightweight runtime for Node.js applications. It offers real-time insights into performance, memory usage, and CPU consumption, giving developers unparalleled visibility into their code without requiring any modifications. In today’s software landscape, understanding your application's production behavior is crucial. With cloud-native architectures, microservices, and distributed systems, pinpointing issues is challenging.

You have built your performance test and executed the tests under load and your tests do not meet your requirements in terms of response times. Or you are unable to execute your tests with the number of concurrent users required. In this post we will give some insights into where you might want to start looking for the root cause of your performance issues.

In this post, the first of a two-part series, we'll cover how Elixir applications can be traced using OpenTelemetry and how macros can make this process super easy and streamlined. First, we'll talk about tracing and OpenTelemetry in Elixir. Then we'll improve our custom tracing layer step-by-step until we get an easy and seamless tool to trace our application. Let's get started!
