New Relic and Splunk are two prominent tools in the world of observability and monitoring, each serving distinct purposes. New Relic is used for Application Performance Monitoring (APM), offering a full-stack observability platform. It is important to note that New Relic is not a SIEM tool, its primary focus is performance monitoring. On the other hand, Splunk is used for log management, machine data analytics, and is widely utilized as a SIEM tool.

Every application tells a story of user intent, system behavior, and business impact. To truly understand how your application performs, you need to go beyond logs and errors. You need metrics that provide actionable visibility across your stack. Application performance metrics are the foundation for delivering high-quality digital experiences, and they empower DevOps teams, developers, engineers, and site reliability engineers (SREs) to respond faster, scale smarter, and continuously improve.

IT budgets are getting squeezed, yet teams are expected to deliver faster releases, higher reliability and tighter security. Observability has become one of the few levers that directly influences IT cost reduction because it gives teams the ability to understand exactly what’s consuming resources, wasting storage, dragging performance, and inflating operational workload. In this guide, you’ll learn seven evidence-backed strategies that leading engineering teams use to cut expenditure.

The distributed tracing landscape has evolved from “observability add-on” to core production infrastructure. In 2026, distributed tracing is no longer optional for engineering teams operating microservices, Kubernetes, or AI-driven workloads. It is now tightly coupled with incident response, cost optimization, and AI-assisted debugging.

If you're working in IT monitoring and observability, you simply cannot ignore the power of Datadog and New Relic. These two tools have plenty of features that can revolutionize your entire observability strategy and give you complete control over your infrastructure. These tools are built so as to capture the tiniest of details, be it on applications, infrastructure, databases, servers, or something completely on the cloud.

Lumigo is a cloud-native observability platform designed primarily for serverless applications and microservices, providing distributed tracing, error detection, and performance monitoring. However, Lumigo may not meet every team's needs due to limitations in features, pricing, scalability, or support for other environments. Many organizations require Lumigo alternatives that provide broader infrastructure monitoring, more advanced analytics, or support for multi-cloud setups.

Backend systems rarely fail in obvious ways. More often, they degrade over time. CPU usage slowly increases, request latency creeps up, and costs rise without a clear explanation. Metrics tell you something is wrong, traces show where requests go, but neither explains why your code behaves the way it does under real load. Continuous profiling fills that gap. Atatus continuous profiling runs automatically in production with minimal overhead.

Datadog is widely recognized for its comprehensive range of products and tools, making it quite a challenge to find a suitable alternative. When seeking an alternative to Datadog, it's essential to conduct a thorough comparison of features, performance, limitations, and other vital aspects. This task requires a deep dive into the details, and it might not be as straightforward as it seems at first glance.

New Relic and Sentry are both popular monitoring tools but they're built for very different problems. If you put them side by side and expect a fair fight, you'll quickly find they don't really compete on the same ground. Sentry is built for developers who want to know exactly what broke, where, and why. It's precise, code-first, and excellent at error tracking.
