Top 8 Distributed Tracing Tools for Microservices in 2025: Features, Pricing & Best Use Cases

Distributed tracing tools are essential for microservices architectures, where a single request can traverse dozens of APIs, databases, and containerized services. The global distributed tracing software market is projected to grow at a 20% CAGR, reaching US$2.5 billion by 2032, driven by Kubernetes, service meshes, and cloud-native adoption. 

But traditional tracing platforms—designed for monoliths—struggle with incomplete context propagation, weak real-time visibility, and expensive data retention. Modern teams need tracing that captures trace IDs and spans across distributed systems, exposing latency, errors, and dependencies that logs or metrics alone cannot resolve.

CubeAPM is one of the best distributed tracing tools for microservices by providing deep visibility into all your services, cross-layer correlation, high granularity spans, SLAs, visualization for service maps, and more. It also offers OpenTelemetry-native support, smart sampling, and on-prem deployment, as well as other useful features. 

In this article, we’ll explore the top distributed tracing tools for microservices—their features, pricing, and best use cases.

What Are Distributed Tracing Tools for Microservices?

Distributed tracing is the process of tracking user requests as they flow through multiple services in a system. Each request is assigned a trace ID, and every step along its journey is recorded as a span. These spans capture timing, metadata, and success or failure signals, which are then stitched together into a complete trace. This gives engineering teams an end-to-end timeline of how requests behave, far beyond what logs or metrics alone can reveal.

In monolithic systems, debugging is simpler because all logic lives in a single codebase. But in microservices, a single action can span dozens of independently deployed services, often managed by different teams. Without distributed tracing, diagnosing issues like cascading failures, bottlenecks, or latency spikes becomes extremely difficult. Distributed tracing fills this gap by mapping dependencies across services and showing exactly where things break down.

Example: Trace the Entire Checkout Flow with CubeAPM

In a microservices-based e-commerce app, a single checkout request may pass through Cart, Pricing, Inventory, Payment, and Shipping services. When the checkout slows down, it’s often unclear which service is to blame.

With CubeAPM’s distributed tracing, every call is automatically tagged with trace and span IDs, letting teams see the full journey in one timeline. Intelligent sampling ensures that error-prone or high-latency spans (e.g., a slow Payment API) are always retained, while keeping storage costs predictable. Engineers can instantly pinpoint the bottleneck, correlate it with logs and metrics, and resolve the issue before it impacts more customers..

Why It Matters? 

Did you know that intelligent sampling can reduce trace storage needs by up to 80% while still preserving almost all critical error and latency insights?

For developers and SREs, distributed tracing reduces mean time to resolution (MTTR) by pinpointing issues in complex microservice chains. For non-technical stakeholders, trace visualizations clearly show how dependencies affect customer experience—for example, explaining why a “slow payment API” might stall the entire checkout process.

Why Teams Choose Different Distributed Tracing Tools for Microservices?

Cost Model vs. Traffic Shape

Microservices often generate high volumes of short-lived requests, leading to unpredictable costs with host-based or per-GB ingestion pricing. Teams look for tools that offer transparent, predictable pricing or cost-saving mechanisms like ingestion-based billing or OSS backends with cheap storage. This ensures observability scales with the business instead of punishing teams as services multiply.

Tail-Based and Dynamic Sampling

Because microservices produce massive amounts of spans, storing every trace is impractical. Teams prefer solutions with tail-based or dynamic sampling, which retain only slow, error-prone, or high-value traces while dropping routine noise. This keeps costs under control without sacrificing the traces needed for effective debugging.

OpenTelemetry Maturity

OpenTelemetry (OTel) has become the standard for microservices instrumentation. The depth of OTel support—collectors, semantic conventions, SDKs—directly influences tool adoption, since teams want vendor flexibility and consistent instrumentation across services. Tools with strong OTel maturity reduce vendor lock-in and speed up onboarding of new microservices.

Kubernetes and Service Mesh Awareness

Modern microservices run on Kubernetes and service meshes like Istio or Linkerd. Engineers choose tracing tools that automatically discover workloads, visualize pod-to-pod traffic, and map service-to-service dependencies without manual setup. This helps teams quickly diagnose cross-service latency inside dynamic, ephemeral environments.

Query Power and Usability for Large Traces

When debugging across dozens of microservices, engineers need fast, expressive query capabilities and intuitive UIs. Features like Grafana’s TraceQL or Honeycomb’s BubbleUp help teams drill into high-cardinality data and spot bottlenecks quickly. Without these capabilities, teams waste valuable time hunting for the right trace among millions.

Correlation Across MELT (Metrics, Events, Logs, Traces)

Distributed tracing alone is not enough. Teams value tools that correlate spans with logs, metrics, and events, enabling a full-stack view of incidents and helping reduce mean time to resolution (MTTR). This correlation accelerates incident response by showing both the what (traces) and the why (logs/metrics).

Data Residency, Retention, and Compliance

In industries like finance or healthcare, compliance is non-negotiable. Teams often select tracing tools that support regional data storage, long retention policies, or on-prem deployment, ensuring regulatory alignment without inflated costs. This also prevents sensitive microservice traces from leaving controlled environments.

Auto-Instrumentation vs. Engineering Effort

With dozens of services to manage, auto-instrumentation can save enormous developer time. Tools like Dynatrace’s OneAgent automate discovery and tracing, while OSS options like Jaeger require more manual setup but provide greater control. The choice often depends on whether teams prefer speed of deployment or long-term customization.

High-Cardinality and Scale Handling

Microservices generate traces tagged with attributes like tenant ID, region, and request IDs. Not all tools handle this well. Teams gravitate toward platforms that can manage high-cardinality data at scale without slowing down queries or dashboards. This capability is crucial for multi-tenant SaaS platforms or globally distributed services.

Top 8 Distributed Tools for Microservices

1. CubeAPM

Overview

CubeAPM is an OpenTelemetry-native application monitoring platform that caters to hybrid and cloud-native microservices.

Pros

• Auto-instrumentation reduces onboarding time in Kubernetes/serverless setups
• Strong AI-based RCA with the help of Davis for service topology
• Unified observability across traces, logs, metrics, RUM, and security
• Large integration ecosystem and full OpenTelemetry compatibility

Cons

• Usage-based pricing model spans multiple dimensions, making it harder to forecast costs
• Costs rise quickly as microservices and data volumes scale
• Less cost-efficient than OSS or flat-rate options for long-term trace storage

Dynatrace Pricing at Scale (10 TB/month example)

Dynatrace pricing is based on a transparent but multi-dimensional model. For distributed tracing with Grail, ingest costs around $0.20 per GiB, with additional charges for retention and queries. At 10 TB/month (~9,300 GiB), ingest alone comes to about $1,860/month, plus retention and compute costs depending on host and pod monitoring. 

In comparison, CubeAPM charges a flat $0.15/GB—roughly $1,500/month for 10 TB ingestion—making it more affordable and predictable for teams focused on trace data volume.

Tech Fit

Dynatrace is best for large-scale, dynamic microservices deployed on Kubernetes, containers, and serverless (AWS Lambda, Azure Functions). It’s well-suited for enterprises that want one platform to cover traces, logs, metrics, user experience, and even security. Dynatrace supports a wide range of languages and frameworks—Java, .NET, Go, Node.js, Python—through OneAgent and OpenTelemetry.

3. New Relic

Overview

New Relic offers a mature distributed tracing solution for microservices. It supports standard (head-based) sampling through its language agents and tail-based sampling with Infinite Tracing. It also natively ingests OpenTelemetry (OTLP), making it easy to bring in data from diverse microservices environments. Its tracing UI allows teams to search, filter, and analyze spans in detail, making it easier to debug complex service chains.

Key Advantage

Flexible sampling with a polished trace UI. Teams can start with standard tracing and then scale into Infinite Tracing to analyze 100% of spans and retain the most important ones. Combined with span-attribute search and interactive waterfalls, New Relic gives engineering teams the visibility they need to manage noisy, high-volume microservices systems.

Key Features

• Standard and tail-based sampling: Choose between agent-led tracing and Infinite Tracing for large-scale microservices.

• Architecture guidance: Documentation and tooling to plan consistent tracing across teams.

Pros

• Mature tracing interface with powerful span queries
• Flexible sampling strategies for microservices at scale
• Strong OpenTelemetry pipeline support
• Wide agent coverage across major languages

Cons

• Can be expensive as services scale because of per GB pricing 
• Infinite Tracing adds extra setup and configuration overhead
• Cost forecasting is harder compared to flat-rate models

New Relic Pricing at Scale (10 TB/month example)

New Relic includes 100 GB/month free, after which ingest is billed at $0.40/GB (with a higher tier at $0.60/GB). A company ingesting 10 TB/month would pay roughly $3,960–$5,940/month, before adding user seats or extras. 

In contrast, CubeAPM’s simpler $0.15/GB pricing costs ~$1,500/month, with no hidden fees. This means it’s more affordable for microservices-heavy environments.

Tech Fit

New Relic is best for teams running diverse microservices architectures that want a balance of agent-based tracing and OTEL ingest pipelines. It works with languages such as Java, .NET, Python, PHP, and others, and integrates with Kubernetes (K8), serverless, and hybrid environments.

4. Datadog

Overview

Datadog offers end-to-end distributed tracing for your microservices. It auto-discovers services, visualizes call graphs with Service Map, lets teams search millions of spans in Trace Explorer, and correlates traces with logs, metrics, RUM, and synthetics. Datadog supports OpenTelemetry ingestion alongside its own tracers and offers built-in controls to manage trace volume through ingestion sampling and intelligent retention filters.

Key Advantage

Microservices-friendly tracing with powerful volume controls. In fast-moving Kubernetes estates that generate huge span volumes, Datadog’s intelligent retention filters and ingestion controls help teams retain slow/error traces and key business flows while shedding routine traffic. Coupled with Service Map and Trace Explorer, this makes it easier to zero in on the exact hop or dependency causing latency without drowning in data.

Key Features

• Service Map and Trace Explorer: Auto-discover microservices, visualize dependencies, and drill into spans and attributes at scale.
• Ingestion sampling & retention filters: Control cost by sampling at the agent/SDK and index only the spans or traces that matter.
• OpenTelemetry support: Ingest OTLP data or run Datadog tracers; mix and match per service.
• Correlated troubleshooting: Pivot from a problematic span to related logs, metrics, RUM sessions, and synthetic tests.
• Guides for data-volume challenges: Sampling strategies and best practices for distributed systems.

Pros

• Deep microservices visualization and span search at scale
• Robust ingestion and retention controls to curb noisy traffic
• 850+ integrations for cloud-native  tech stacks
• Strong workflows to connect traces with logs and metrics, as well as RUM and synthetics

Cons

• Complex pricing across hosts, indexed spans, and add-ons
• Total cost often rises with microservices growth and higher trace retention needs
• Difficulty with tune sampling and indexing

Datadog Pricing at Scale (10 TB/month example)

Datadog uses a modular model. APM is billed per APM host (commonly around $31–$40/host/month) plus usage for ingested and indexed spans; logs, RUM, and synthetics are separate line items. If a mid-sized team runs, say, 150 APM hosts, host licensing alone is roughly $4,650–$6,000/month, before adding ingestion and indexing charges for traces. 

By contrast, CubeAPM’s flat $0.15/GB keeps 10 TB/month ≈ $1,500 with hosts, users, and synthetics included—far more predictable for trace-heavy microservices.

Tech Fit

Best for teams that want a unified SaaS platform with mature microservices maps, span search, and strong ecosystem integrations. Works well across Java, .NET, Go, Node.js, Python, Ruby, and in Kubernetes/serverless environments using either Datadog tracers or OpenTelemetry pipelines.

5. Jaeger

Overview

Jaeger is a CNCF-graduated, open-source distributed tracing system originally built at Uber and widely adopted for microservices. In late 2024, it released Jaeger v2, which re-architects core components on top of the OpenTelemetry Collector and tightens OTEL compatibility—making it easier to plug into modern, vendor-neutral pipelines while scaling out in Kubernetes and hybrid clouds.

Key Advantage

Vendor-neutral, OTEL-first tracing that you can control end-to-end. Jaeger excels when you want maximum flexibility: instrument with OpenTelemetry, route data through the Collector, and choose your own storage (OpenSearch/Elasticsearch or Cassandra) with retention tuned to your microservices’ needs. This gives teams fine-grained control over sampling, retention, and costs—without licensing fees.

Key Features

• OpenTelemetry support: Jaeger v2 is built on the OTEL Collector, which simplifies the instrumentation process for different programming languages and services.
• Multiple storage backends: Supports OpenSearch/Elasticsearch, Cassandra, Kafka as buffer, Badger/memory for dev and small setups.
• Service dependency graphs and trace UI: Visualize cross-service call paths, latency, and error hotspots in microservices.
• Adaptive sampling: Keep high-value traces (errors/slow paths) while reducing noise at scale.
• Kubernetes-friendly deployment: Proven patterns with the Jaeger Operator and OTEL Collector for cluster-wide tracing.

Pros

• No license fees; full control over data and retention
• OTEL-first architecture; easy to standardize instrumentation across services
• Flexible storage choices to balance performance and cost
• Scales horizontally; mature in Kubernetes environments

Cons

• You run and operate the stack (storage clusters, upgrades, backups)
• Query performance and index tuning require SRE effort at higher volumes
• UI/analytics are simpler than commercial suites; advanced analytics need add-ons
• Long-term retention can become expensive without careful sampling/tiers

Jaegar Pricing at Scale (10 TB/month example)

Jaeger is free and open source, which means no license cost. At 10 TB/month of traces, your expense is the infrastructure: cluster compute, storage, and operational overhead. Typical large-scale setups use OpenSearch/Elasticsearch with replication and hot/warm tiers; costs depend on retention goals, compression, and query demands. 

Teams that need predictable spend often compare this variable TCO to CubeAPM’s flat $0.15/GB, which puts the same 10 TB/month at about $1,500 with no host or user-based add-ons. 

If you already operate large search clusters and optimize sampling, Jaeger can be cost-effective; if you don’t want to own the plumbing, CubeAPM is usually cheaper and simpler at this scale.

Tech Fit

Best for OTEL-standardized microservices that prefer self-hosted control and composability. Works across all major languages via OpenTelemetry SDKs and auto-instrumentation and deploys cleanly to Kubernetes with the Jaeger Operator and OTEL Collector. Choose OpenSearch/Elasticsearch for powerful search or Cassandra for write-heavy, ID-based lookups, depending on workload.

6. Zipkin

Overview

Zipkin is a lightweight, open-source distributed tracing system widely used in microservices—especially in Java/Spring ecosystems. It implements a simple model (traces, spans, annotations) and a clean API that many frameworks and proxies can emit to, making it easy to drop into existing architectures and start following requests across services.

Key Advantage

Straightforward, low-overhead tracing for teams that want quick visibility with minimal ceremony. Zipkin’s simplicity, broad emitter support (e.g., Spring/Micrometer, Brave), and easy deployment make it a practical choice for engineering teams who want to instrument microservices without adopting a heavy, full-suite platform.

Key Features

• Service and dependency graphs: Visualize how services call one another to spot hot paths and fan-out/fan-in patterns.
• Trace and span search: Filter by service, operation, latency, tags, and time windows to find problem requests fast.
• Multiple storage backends: Run dev/test in-memory, or persist production traces in Elasticsearch, Cassandra, or MySQL.
• Flexible ingestion formats: Accepts Zipkin/Brave emitters and Zipkin-compatible exports from gateways, sidecars, and meshes.
• Kubernetes-friendly deployment: Simple Docker/K8s manifests for shipping spans from pods/namespaces to a central collector.

Pros

• Easy to deploy and operate for small to mid-sized microservices estates
• Well supported in Java/Spring via Micrometer/Brave; community clients exist for many languages
• Zipkin API compatibility across proxies/meshes and libraries makes onboarding fast
• No license cost; you control retention and data footprint

Cons

• UI and analytics are basic compared to commercial suites
• Typically, head-based sampling and tail-based workflows require custom pipelines
• Operating Elasticsearch/Cassandra/MySQL for larger volumes adds SRE overhead
• Limited native correlation with logs/metrics; you’ll stitch tools yourself

Zipkin Pricing at Scale (10 TB/month example)

Zipkin itself is free; your cost is infrastructure. At 10 TB/month of traces, expect expenses in storage (e.g., Elasticsearch/Cassandra clusters with replication, hot/warm tiers), compute for ingestion/query, and ops time. 

Teams already running search clusters can tune retention and sampling to keep costs down; teams that don’t want to manage storage often find CubeAPM’s flat $0.15/GB simpler and cheaper at this scale—about $1,500/month for the same 10 TB, without host/user/synthetics add-ons.

Tech Fit

A great fit for Java/Spring Boot microservices and teams standardizing on Micrometer/Brave, with workable paths for Go, Node.js, Python, and .NET via community emitters and Zipkin-compatible exporters. Works well in Kubernetes when you want a small, self-hosted tracer that integrates with gateways, sidecars, and service meshes emitting Zipkin-format spans.

7. Grafana Tempo

Overview

Grafana Tempo is a high-scale, open-source tracing backend built for cloud-native microservices. It ingests spans from OpenTelemetry, Jaeger, or Zipkin, stores them cheaply in object storage (S3, GCS, Azure), and lets you explore traces in Grafana using TraceQL, a query language designed for distributed tracing. Tempo is also available fully managed as Grafana Cloud Traces if you don’t want to operate it yourself.

Key Advantage

Low-cost, scalable trace storage for Kubernetes-heavy microservices. Tempo avoids heavyweight indexing and relies on object storage, which keeps costs down as span volumes grow. When paired with Grafana, teams can drill into traces with TraceQL, link a span to its logs and metrics, and build workflows that accelerate debugging across multi-service environments.

Key Features

• OpenTelemetry native: makes migration easier with OTLP-based ingestion as well as Jaeger/Zipkin formats.
• TraceQL for powerful queries: Filter on span attributes, timing, and relationships; use aggregates to surface bottlenecks.
• Object-storage architecture: Store traces in S3/GCS/Azure for massive scale at lower cost.
• Grafana integration: Explore traces in Grafana, pivot to related logs/metrics, and generate metrics from traces.
• Managed option: Grafana Cloud Traces provides a hosted Tempo with a free tier (50 GB traces, 14-day retention).

Pros

• Scales economically on object storage for high-volume microservices
• Strong OTEL, Jaeger, and Zipkin compatibility for gradual migrations
• TraceQL provides expressive, fast querying at scale
• First-class Grafana experience for linking traces with logs and metrics

Cons

• DIY deployments require SRE effort for upgrades, capacity, and retention policies
• Advanced “metrics from traces” is still experimental in managed offerings
• Lacks some AI-driven root cause features of enterprise suites

Grafana Tempo Pricing at Scale (10 TB/month example)

With Grafana Cloud Traces, pricing starts at $0.50 per GB ingested. At 10 TB/month (~10,000 GB), the bill comes to about $5,000/month, not including add-ons or extended retention. 

In contrast, CubeAPM’s flat $0.15/GB keeps the same 10 TB at roughly $1,500/month, with hosts, users, and synthetics included—far more predictable for microservices-heavy teams.

Tech Fit

Tempo is a strong fit for Kubernetes and service-mesh environments that generate large span volumes and want OTEL-first pipelines with economical storage. It’s compatible with languages such as Java, Go, Python, .NET , and Go via OTEL SDKs. It also pairs with Grafana to help you troubleshoot issues related to traces, logs, and metrics.

8. Honeycomb

Overview

Honeycomb is a developer-centric observability platform with powerful distributed tracing for microservices. It’s built to explore high-cardinality data quickly, correlate spans with rich attributes, and surface outliers via interactive visual analysis. Honeycomb supports OpenTelemetry pipelines and offers Refinery for tail-based sampling, plus a growing ecosystem around trace-based testing with Tracetest.

Key Advantage

High-signal debugging at microservices scale. Honeycomb’s combination of tail-based sampling (Refinery) and BubbleUp anomaly detection helps teams keep only the most valuable traces (errors, latency spikes, rare paths) and then pinpoint exactly which fields differ from normal traffic—ideal when thousands of spans per second make traditional triage noisy.

Key Features

• Distributed tracing UI and waterfalls: Follow requests across services, drill into spans/attributes, and jump to the slow or failing hop fast.
• BubbleUp anomaly detection: Select outliers on a heatmap to see which attributes explain the difference.
• Tail-based sampling: The tool lets you keep “interesting” traces and drops noise to help you manage expenses.
• OpenTelemetry ingest & pipelines: Use OTLP/Collector to standardize instrumentation across languages and services.
• Trace-based testing with Tracetest: Turn real traces into pre-prod checks to prevent regressions in complex microservice chains.

Pros

• Excellent at high-cardinality, exploratory debugging for complex microservices
• Tail-based sampling keeps costs predictable without losing critical signal
• Strong docs and workflows for OTel pipelines and trace analysis
• Ecosystem support for trace-based testing and modern DevEx practices

Cons

• Event-based pricing (per event) can be harder to map to GB-style budgets
• Tail-sampling adds components to operate and tune
• Lighter on “all-in-one” features compared to broad enterprise suites

Honeycomb Pricing at Scale (10 TB/month example)

Honeycomb prices by events, not by GB. The public pricing page shows Pro from $100/month and Enterprise starting with 10 billion events/year, with volume tiers. Translating 10 TB/month of trace data to events depends on your average span size; as a rough illustration, if your average event were ~1 KB, 10 TB ≈ 10 billion events per month—well above the base Enterprise yearly allowance and into negotiated tiers. 

By contrast, CubeAPM’s flat $0.15/GB is straightforward: 10 TB/month ≈ $1,500/month, with hosts/users/synthetics included, which is typically more predictable for trace-heavy microservices.

Tech Fit

Great for Kubernetes- and service-mesh-heavy microservices that need fast, exploratory debugging across millions of spans. Works smoothly with OpenTelemetry across major languages (Java, Go, Node.js, Python, .NET). Teams that value tail-sampling + interactive analytics often find Honeycomb a strong complement—or alternative—to traditional APMs.

How to Choose the Right Distributed Tracing Tool for Microservices

OpenTelemetry Depth and Vendor Neutrality

Microservices involve many languages and frameworks. A tracing tool must provide strong OpenTelemetry (OTel) support, including OTLP ingest and Collector pipelines, so teams can instrument once and switch backends without lock-in.

Context Propagation Across Services and Meshes

Requests often span HTTP calls, message queues, and service meshes like Istio or Linkerd. The right tool must reliably propagate context across these hops, ensuring traces stay stitched together even in async or retry-heavy workflows.

Tail-Based Sampling for High-Volume Traffic

Microservices generate millions of spans per second. Tools with tail-based or intelligent sampling keep error, latency, and rare traces while discarding routine noise—essential for controlling costs and keeping signal quality high.

Cost Model Aligned With Traffic Shape

Pricing surprises are common when every span, pod, or GiB of ingest adds to the bill. Teams should test how a tool’s pricing scales with bursty microservices traffic and high-cardinality workloads. Predictable models win in production.

Query Power for Complex Traces

With dozens of services in a single request, teams need expressive, fast queries. Features like attribute-based search, filters, and aggregates help engineers isolate “service X in region Y failed for tenant Z” scenarios quickly.

Kubernetes and Service Mesh Awareness

Most microservices run in Kubernetes, often with sidecar proxies. A tool should auto-discover pods, containers, and services, map their dependencies, and integrate cleanly with service meshes to avoid broken traces.

Correlation With Logs, Metrics, and User Data

Tracing alone shows what failed, but not why. Strong platforms let teams pivot from a hot span to related logs, metrics, or RUM data, reducing mean time to resolution (MTTR) in distributed environments.

Retention, Governance, and Data Residency

Microservices often handle sensitive data. A tracing solution must allow on-prem or regional storage, configurable retention, and fine-grained sampling to stay compliant while managing long-term trace data effectively.

SaaS Convenience vs. DIY Control

Large microservices estates can overwhelm SRE teams if self-hosted. Some organizations prefer SaaS platforms for simplicity, while others need open-source backends for cost control and custom retention policies.

Developer-Centric Workflows

Microservices debugging happens daily. Tools with fast UIs, high-cardinality exploration, and trace-based testing make developers more productive and accelerate root cause analysis across complex service chains.

Conclusion

Choosing the right distributed tracing tool for microservices isn’t easy. Teams face challenges like exploding span volumes, broken traces across service meshes, limited sampling options, and unpredictable pricing that balloons as traffic grows. Debugging latency or errors in requests that touch dozens of services is nearly impossible without the right platform.

This is where CubeAPM makes a difference. It delivers end-to-end distributed tracing, AI-driven smart sampling, root cause analysis, and real-time service maps that clearly show dependencies across microservices. Features like high-granularity spans and cross-layer correlation help teams catch issues early, while OpenTelemetry-native ingest ensures consistent instrumentation across all services.

If you’re ready to gain end-to-end visibility into your microservices while cutting costs, CubeAPM is the best choice for distributed tracing in 2025. Get started today and give your teams the clarity they need to resolve issues faster.
