Perform Distributed Tracing for your MCP system with OpenTelemetry

2025 has truly been the year of Agentic AI, with MCP (Model Context Protocol) emerging as one of its flashy and most talked-about innovations. While many products have seamlessly integrated MCP servers into their systems, these servers are increasingly being labelled as black boxes, opaque components that handle critical tasks but offer little visibility into what’s happening under the hood. We prompt an agent, a tool gets invoked, and a response is generated. But what really happens in between? And when something breaks, how do we trace the failure and debug it effectively?

Faster incident response through distributed tracing: Inside Glovo's use of Traces Drilldown

It’s almost 1 p.m. on a Monday afternoon and you’re hungry. You pull up your meal delivery app and select your favorite restaurant and dish. Then you go to check out and nothing happens. Your frustration mounts as you get hungrier by the minute. But there’s frustration on the other side of that transaction as well—engineers are scrambling to figure out what’s wrong as orders drop and revenue losses rise.

Understanding APM and Distributed Tracing in the Observability Stack

To keep modern applications running smoothly, you need more than just basic monitoring. APM (Application Performance Monitoring) gives you a broad overview, tracking metrics like latency, errors, and system health. Distributed Tracing, on the other hand, shows the full journey of each request across services, helping you pinpoint the root cause of slowdowns or failures.

OpenTelemetry vs Fluent Bit - Key Differences 2025

Modern applications demand strong observability to ensure performance, reliability, and quick troubleshooting. Two powerful open-source tools, OpenTelemetry and Fluent Bit play key roles in this space. While OpenTelemetry offers a full-stack framework for collecting metrics, logs, and traces, Fluent Bit specializes in fast, lightweight log forwarding.

Coralogix adds OTel-based service dependency tracking for distributed systems

Coralogix has released its APM Dependencies feature. This feature automatically surfaces and maps the relationships within and between your software and external services. It allows fine grained tracking of which endpoints within your APIs, depend on other endpoints, or external services and database tables.

Slash Observability Costs Without Sacrificing Reliability: The OTEL + PagerDuty Advantage

In a time when budgets are tight but reliability still needs to be high, observability is under the spotlight. Monitoring and observability tools are some of the most expensive parts of a tech stack, often eating up the bulk of the budget. Luckily, there are strategies organizations can implement to reduce costs, such as utilizing open-source solutions like OpenTelemetry (OTEL), which provides a flexible, open standard for data collection without the price tag of proprietary tooling.

Structured Logging in NextJS with OpenTelemetry

Traces tell you what happened and when. Logs tell you why. When something breaks, logs are often your first clue—and if they’re correlated with traces, they can cut debugging time down from hours to minutes. In this section, we’ll wire up end-to-end structured logging across both server and browser environments in your Next.js app, complete with trace correlation and SigNoz integration.
