What is Observability?

What is Observability? Observability is the ability to gain insights into the internal state of a system by examining its external outputs. It involves collecting and analyzing telemetry data, such as logs, metrics, and distributed traces from various sources to understand how a system behaves, and performs, enabling effective monitoring, debugging, and understanding of system […]

What are Microservices?

Microservices have redefined how developers design, build and deploy mission-critical production software. Therefore, it’s essential to understand what microservices are, what they mean for developers, and the benefits and challenges it creates for software teams. What are Microservices? Microservices are a software architecture pattern that structures an application as a collection of small, independent, and […]

What is eBPF?

What is eBPF? eBPF, or Extended Berkeley Packet Filter, is a kernel technology available since Linux 4.4. It lets developers run programs without adding additional modules or modifying the kernel source code. Think of it as a lightweight, sandboxed virtual machine (VM) within the Linux kernel that lets you run Berkeley Packet Filter (BPF) bytecode […]

What is OpenTelemetry (OTel)?

Introduction to OpenTelemetry (OTel) OpenTelemetry is an open-source observability framework designed to collect, instrument, and export telemetry data from software applications, systems, and infrastructure. OpenCensus and OpenTracing OpenTelemetry builds upon the success of two previous observability projects, OpenCensus and OpenTracing, and combines them into a unified, standardized solution. This merger provides comprehensive support for both metrics and traces. Vendor-Agnostic […]

What is Distributed Tracing?

What is Distributed Tracing? Distributed tracing is a method of monitoring request paths across distributed environments using unique identifiers. It tracks interactions with microservices, containers, and infrastructure, offering valuable performance insights. It allows developers to identify performance bottlenecks, troubleshoot issues, and optimize the system. In a distributed system, a single request often triggers a chain […]

What is a Span?

What is a span? At its core, a span represents the lifecycle of a single operation within a system. It serves as a vital building block, offering valuable context and insights into the behavior of applications. 1. What is the role of spans in observability? Spans let developers track the flow of requests across complex […]

What is a Trace?

What is a Trace? A trace refers to the end-to-end monitoring and tracking of a user request as it flows through multiple microservices. It is part of distributed tracing, a technique used to understand the flow of requests and responses across various microservices that collaborate to provide a complete service. Tracing is one of the […]

What is Application Performance Monitoring (APM)?

Application Performance Monitoring (APM) incorporates telemetry data and monitoring tools to track and manage the performance of business-critical applications. It is widely used in applications to help monitor system availability, reliability, service performance optimization, and response times. It is crucial for optimizing application performance and presenting clients with an exceptional user experience. Features of Application Performance Monitoring […]
