In this context, traditional <a href=\"https:\/\/pandorafms.com\/en\/it-topics\/infrastructure-monitoring\/\" target=\"_blank\" rel=\"noopener nofollow\">infrastructure monitoring<\/a> struggles to deliver a complete view of system behavior. That\u2019s why <a href=\"https:\/\/learn.microsoft.com\/en-us\/dotnet\/core\/diagnostics\/distributed-tracing\" target=\"_blank\" rel=\"noopener nofollow\">distributed tracing<\/a> helps developers and IT administrators visualize the full journey of requests and makes it easier to identify performance, potential bottlenecks, and failures\u2014as well as when they occur.<\/p>\n<h2 id=\"2\">What is distributed tracing?<\/h2>\n<p><strong>Functional and technical definition<\/strong><\/p>\n<p>Distributed tracing makes it possible to observe data requests as they flow through a distributed system. Modern microservices architectures consist of diverse, independent components where data exchanges happen through <a href=\"https:\/\/definicion.de\/api\/\" target=\"_blank\" rel=\"noopener nofollow\">APIs<\/a>. Functionally, distributed tracing enables continuity of tracking because each request has a unique trace ID across multiple services; it can establish span hierarchies within a service; it leverages tracing libraries (e.g., OpenTelemetry, Jaeger) to collect trace data; and it integrates contextual logging (combining logs and metrics), providing full observability. In addition, traces can be recorded based on predefined rules.<\/p>\n<p>From a technical standpoint, distributed tracing helps you understand how requests flow through distributed systems; it allows bottlenecks and potential latency to be identified; it pinpoints failures and accelerates debugging. It can also be used for resource allocation based on information about dependencies and load distribution. Moreover, it fosters team collaboration by tracking interactions between services and the owners of those services.<\/p>\n<p><strong>Differences from traditional logging and metrics<\/strong><\/p>\n<p>Tracing is the bridge between traditional logging, metrics, and distributed tracing. To understand their differences, the depth of insight, and how they complement each other, the following table illustrates it clearly.<\/p>\n<p><strong>Table \u2013 Differences between distributed tracing, traditional logging, and metrics<\/strong><\/p>\n<table class=\"PandoTable\">\n<tbody>\n<tr>\n<td>\n<p><strong>Objective<\/strong><\/p>\n<\/td>\n<td>\n<p><strong>Depth level \/ highest effectiveness<\/strong><\/p>\n<\/td>\n<td>\n<p><strong>Use case<\/strong><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p><strong>Distributed tracing<\/strong><\/p>\n<\/td>\n<td>\n<p>Tracks requests across multiple services, providing end-to-end visibility.<\/p>\n<p>Captures detailed interactions between services, showing latency and dependencies.<\/p>\n<\/td>\n<td>\n<p>Diagnoses performance bottlenecks and service failures in distributed systems.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p><strong>Logging<\/strong><\/p>\n<\/td>\n<td>\n<p>Records system events, errors, and activities.<\/p>\n<p>Provides historical context for debugging but does not offer visibility across multiple services.<\/p>\n<\/td>\n<td>\n<p>Error tracking, auditing, and forensic analysis.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p><strong>Metrics<\/strong><\/p>\n<\/td>\n<td>\n<p>Monitors system health by collecting numerical data.<\/p>\n<p>Aggregates data over time (historical), supporting trend analysis and alert generation.<\/p>\n<\/td>\n<td>\n<p>Detect anomalies and predict failures before they occur.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>As you can see, all of them provide useful findings for your team. However, logs and metrics alone are not sufficient to understand what is happening within the complexity of distributed systems. Traces are information resources that enhance observability through correlation and context, linking resources, services, and dependencies. Thus, distributed tracing is a powerful capability to understand complex service interactions in modern architectures to achieve stable systems and better experiences for users and customers.<\/p>\n<h2 id=\"3\">How distributed tracing works<\/h2>\n<p>Distributed tracing provides visibility into how different microservices interact, based on the components reflected in the following diagram:<\/p>\n<ul class=\"lista\">\n<li><strong>Trace initiation:<\/strong> When a user makes a request, it generates a unique <em>trace ID<\/em> that follows the request across multiple services.<\/li>\n<li><strong>Span creation:<\/strong> Each service the request interacts with creates a span, representing a single operation (examples: a web page query, database access, API calls). Spans form a <em>trace<\/em>, which shows the full journey of the request.<\/li>\n<li><strong>Context propagation across services:<\/strong> The <em>trace ID<\/em> and span data are transmitted between services via headers in <a href=\"https:\/\/pandorafms.com\/en\/network-monitoring\/\" target=\"_blank\" rel=\"noopener nofollow\">network<\/a> requests, ensuring continuity and allowing observability tools to reconstruct the request flow.<\/li>\n<li><strong>Data collection and visualization (<a href=\"https:\/\/pandorafms.com\/en\/it-topics\/telemetry-management-infrastructures-pandora-fms\/\" target=\"_blank\" rel=\"noopener nofollow\">telemetry<\/a>):<\/strong> Tracing tools collect span data such as latency, errors, and dependencies. The trace is visualized as a flame graph, timelines, or waterfall charts to help your engineering team identify bottlenecks.<\/li>\n<li><strong>Troubleshooting and optimization:<\/strong> With these insights, your team can identify services exhibiting latency, failures, or inefficient interactions. This information is also valuable for defining strategies in <a href=\"https:\/\/pandorafms.com\/en\/it-topics\/it-project-management\/\" target=\"_blank\" rel=\"noopener nofollow\">IT project management<\/a> to optimize performance, improve reliability, and streamline debugging.<\/li>\n<\/ul>\n<p><center><\/p>\n<p><strong>Figure \u2013 How Distributed Tracing Works<\/strong><\/p>\n<p><\/center><br \/>\n<img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" class=\"lazyload\" data-src=\"https:\/\/pandorafms.com\/wp-content\/uploads\/2025\/08\/Distributed-Tracing_Graphics.png\"><\/p>\n<h2 id=\"4\">Distributed tracing in microservices architectures<\/h2>\n<p><strong>Why microservice tracing is essential<\/strong><\/p>\n<p>Distributed tracing helps developers and system administrators visually follow the path of requests across different microservices. This visibility enables teams to correct errors and performance issues that could ultimately impact customer experience.<\/p>\n<p><strong>End-to-end tracing<\/strong><\/p>\n<p>Distributed tracing enhances comprehensive monitoring with full visibility into complex, distributed systems by leveraging unified observability (integrating logs and metrics) and context propagation across all microservices, facilitating end-to-end request tracking. It also helps optimize performance by identifying bottlenecks and latency issues throughout the request lifecycle. All this information helps engineers detect failures faster by correlating traces with logs and metrics.<\/p>\n<p><strong>Common use cases:<\/strong><\/p>\n<ul class=\"lista\">\n<li><strong>API gateways:<\/strong> An application user makes a request, and the gateway forwards it to different services while assigning a trace ID to the request. Each microservice involved creates spans to track execution time. The trace is propagated between services via headers. With this, distributed tracing provides engineers with comprehensive visibility into potential bottlenecks.<\/li>\n<li><strong>Message queues:<\/strong> In <a href=\"https:\/\/pandorafms.com\/es\/monitorizacion-de-aplicaciones\/\" target=\"_blank\" rel=\"noopener nofollow\">application monitoring<\/a> such as email dispatching, distributed tracing allows analysis of how long processing takes and, based on that, defines strategies to optimize message delivery.<\/li>\n<li><strong>Serverless functions:<\/strong> In serverless environments, where execution is ephemeral, debugging performance issues can be a challenge for your team. Here distributed tracing provides end-to-end visibility of the request flow across different services.<\/li>\n<\/ul>\n<h2 id=\"5\">Advantages of distributed tracing<\/h2>\n<ul class=\"lista\">\n<li><strong>Detection of bottlenecks and errors:<\/strong> With complete end-to-end visibility, distributed tracing enables visualization of each service\u2019s response time, helping to quickly detect where delays and potential bottlenecks are generated.<\/li>\n<li><strong>Reduction of MTTD and MTTR:<\/strong> For failure detection (<em>MTTD<\/em>, Mean Time to Detect), distributed tracing provides real-time visibility into requests and their interactions across microservices, helping identify anomalies and failures quickly. For issue resolution (<a href=\"https:\/\/pandorafms.com\/en\/it-topics\/mttr\/\" target=\"_blank\" rel=\"noopener nofollow\">MTTR<\/a>, Mean Time to Resolve), distributed tracing helps locate the failure precisely by showing which service or component is causing the error or requires <a href=\"https:\/\/pandorafms.com\/en\/it-topics\/effective-patch-management\/\" target=\"_blank\" rel=\"noopener nofollow\">patching<\/a>.<\/li>\n<li><strong>Improved SLAs, performance, and user experience:<\/strong> Distributed tracing helps monitor <a href=\"https:\/\/pandorafms.com\/en\/it-topics\/uptime-monitoring\/\" target=\"_blank\" rel=\"noopener nofollow\">uptime<\/a> and <a href=\"https:\/\/pandorafms.com\/en\/it-topics\/what-is-an-sla-best-practices-for-service-level-agreements\/\" target=\"_blank\" rel=\"noopener nofollow\">Service Level Agreement<\/a> compliance by detecting response times and availability in real time. By reducing load times and errors, user perception of speed and reliability improves, resulting in a better experience.<\/li>\n<li><strong>Cross-team collaboration (DevOps, SRE, QA):<\/strong> Full visibility enables a shared view across your company\u2019s teams regarding system performance and stability. In DevOps, it helps detect issues in deployment and software optimization; in SRE (Site Reliability Engineering), it helps identify bottlenecks and improve resilience by leveraging detailed trace analysis.<\/li>\n<\/ul>\n<h2 id=\"6\">Challenges and limitations<\/h2>\n<ul class=\"lista\">\n<li><strong>Manual vs. automatic instrumentation:<\/strong> Implementing and maintaining distributed tracing requires instrumenting each service, which can be complex and time-consuming. Also consider that most (or all) legacy systems don\u2019t support automatic instrumentation, which may demand manual changes.<\/li>\n<li><strong>Cost and data volume:<\/strong> Capturing traces for each request can generate an overwhelming volume of data, impacting system performance as well as your team\u2019s time and resource costs.<\/li>\n<li><strong>Sampling issues and incomplete context:<\/strong> Due to the high volume of trace capture, sampling strategies must be applied to avoid overload, which may imply loss of relevant information or incomplete context. In addition, automatically collecting data and integrating it across multiple services and tools\u2014beyond being complex\u2014can expose sensitive information if not properly managed.<\/li>\n<\/ul>\n<h2 id=\"7\">How distributed tracing integrates with Pandora FMS<\/h2>\n<p>Pandora FMS can integrate with distributed tracing solutions such as <a href=\"https:\/\/www.jaegertracing.io\/\" target=\"_blank\" rel=\"noopener nofollow\">Jaeger<\/a> or <a href=\"https:\/\/opentelemetry.io\/\" target=\"_blank\" rel=\"noopener nofollow\">OpenTelemetry<\/a> to incorporate traces into its monitoring console.
