Welcome to our monthly product newsletter - SigNal 22! Last month our team worked on improving the logs tab and improved the correlation between telemetry signals to drive contextual insights faster. We were also trending on GitHub and crossed 2000+ developers in our slack community. Let’s dive in to see what humans at SigNoz were up to in the month of February 2023.

A few months ago, I wrote an article about a serious outage of Azure and how eG Enterprise enabled us and our customers to understand the issue long before Microsoft had confirmed the issue and updated their service status pages.

The observability landscape - specifically your traditional Application Performance Monitoring (APM) offerings are failing modern-day developers. These legacy tools are made for ops and infra teams to keep their infrastructure and services up and running. But when it comes to helping the people that actually write the code to find and fix latency issues, these tools - which often come with massive price tags - leave developers hunting for issues causing slowdowns.

At Raygun, we’re a pretty polyglot group of developers. Various parts of our code base are written in different languages and frameworks — whatever is best for the job. That said, large parts of Raygun written with.NET, and we’re big.NET fans. Given the prevalence of C# applications (C# has been in the top 5 on the TIOBE index for about 10 years!) and the massive scale of data Raygun deals with, we’re often called on to do C# optimization work.

Monitoring and troubleshooting distributed systems like those built with microservices is challenging. Traditional monitoring tools struggle with distributed systems as they were made for a single component. Distributed tracing solves this problem by tracking a transaction across components. In this article, we will implement distributed tracing for a Java Spring Boot application with three microservices.

eG Enterprise is designed to be deployed automatically at scale within IaC type workflows and by products such as Nerdio Manager that facilitate automation. Deployment of eG Enterprise can be automated with or without Nerdio Manager. Many of our customers do choose Nerdio Manager to automate other workflows and to create and manage images for Azure Virtual Desktop (AVD) deployments.

OpenTelemetry is an open-source standard for instrumenting cloud-native applications for generating different types of telemetry data. A robust observability framework set up using OpenTelemetry can help tremendously while troubleshooting software in production. Nginx is one of the most widely adopted web servers. Most often, nginx is used as a reverse proxy. It serves the frontend or backend applications behind the reverse proxy.

OpenTelemetry consists of several main components. But to understand the architecture, we will start by understanding some of the key design principles behind the design and architecture of OpenTelemetry. But before that, let us have a brief overview of OpenTelemetry.
