In a recent conversation on our SigNoz community Slack, a user shared their query that asks a deceptively simple question: what is the average time between two spans in a trace? The usefulness of this answer is evident if you think about how often the total trace time does not highlight the time you care about most. This could mean any number of things: that the total trace time of handling a web request might include lots of spans after a satisfying response was sent to the user.

Many of us have heard single-page applications (SPAs) hailed as the future of web applications. Proponents of SPAs point to increased code reusability and development velocity, and the advantage SPAs can give when it comes to delivering a fast and seamless user experience. Massive sites like Facebook, AirBnB and Trello are all built as SPAs. On the flipside, monitoring SPAs for performance is pretty challenging.

The Garbage Collection (GC) feature in the Java Virtual Machine (JVM) is truly remarkable. It automatically identifies and cleans up unused Java objects without burdening developers with manual allocation and deallocation of memory. As an SRE or Java Administrator you need a strong understanding of the Java Garbage Collection mechanism to ensure optimal performance and stability of your Java applications.

APM is one of those buzzwords that is slowly becoming a necessity. Most people are still unsure what APM means and how it can help their services. But what is it? What does it stand for? And how can it help your services or digital products? This blog will answer your questions—and more.

In this article, we will implement distributed tracing for a Golang application with three microservices. To implement distributed tracing, we will be using open-source solutions - SigNoz and OpenTelemetry, so you can easily follow the tutorial.

gRPC (Google Remote Procedure Call) is a high-performance, open-source universal RPC framework that Google developed to achieve high-speed communication between microservices. gRPC has Protobuf (protocol buffers) by default which would format or serialize the messages to a specific format that will be highly packed, highly efficient data. By its virtue of being a lightweight RPC, gRPC is suited for many use-cases. gRPC can be considered a successor to RPC, which is light in weight.

OpenTelemetry can be used to trace Gin applications for performance issues and bugs. OpenTelemetry is an open-source project under the Cloud Native Computing Foundation (CNCF) that aims to standardize the generation and collection of telemetry data like logs, metrics, and traces. Gin is an HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin!

For Software Houses, developers are as important as customers are to a retail organization – if the Developer Experience (DX / DevExp / DevEx) is poor, then work simply will not get done effectively and the best and the brightest are likely to leave for an employer who offers a better experience and hence, more productivity and job satisfaction. Long-term frustrated employees and staff attrition tend to impact product quality and lead to weaker software applications.
