To visualize distributed traces, you need to set up distributed tracing in your environment. This section explains the requirements, how to instrument your services, and collect trace data, as well as popular open-source standards.
To implement distributed tracing, you'll need:
Instrumentation involves adding code to your services to capture trace data, such as request and response headers, timestamps, and error messages. This data is then sent to a tracing backend.
Supported languages and frameworks include Java, Python, Node.js, and .NET. Popular instrumentation libraries include:
| Library | Description |
|---|---|
| OpenTelemetry | Provides SDKs, data collection software, and vendor-neutral APIs and tools for instrumentation. |
| OpenTracing | A vendor-agnostic API that assists developers in instrumenting code for distributed tracing. |
| Jaeger | An open-source distributed tracing system for monitoring and troubleshooting microservices-based applications. |
OpenTelemetry and OpenTracing are key standards for implementing distributed tracing. These standards provide a vendor-neutral approach, allowing you to switch between tracing backends without modifying your application code.
OpenTelemetry combines OpenCensus and OpenTracing, offering:
OpenTracing is a vendor-agnostic API that helps developers instrument code for distributed tracing.
Selecting the right tool for visualizing distributed traces is crucial. Here, we'll explore popular options, compare their features, and provide guidance on choosing the best fit for your needs.
Several tools are available for distributed trace visualization, each with its strengths:
Here's a comparison of the tools' key features:
| Tool | Instrumentation | Data Collection | Visualization | Scalability | Cost |
|---|---|---|---|---|---|
| Jaeger | OpenTelemetry, OpenTracing | In-memory, Cassandra, Elasticsearch | Service maps, trace graphs | High | Free (open-source) |
| Zipkin | OpenZipkin, Brave | In-memory, Cassandra, MySQL | Service maps, latency graphs | Medium | Free (open-source) |
| Honeycomb | Automated | SaaS-based | Customizable dashboards, service maps | High | Paid (commercial) |
| Grafana Tempo | OpenTelemetry, OpenTracing | In-memory, Cassandra, Elasticsearch | Service maps, trace graphs | High | Free (open-source) |
When choosing a tool, consider the following:
Setting up a distributed tracing tool involves several steps, including installation, configuration, integration, and troubleshooting. Here, we'll guide you through the process of setting up Jaeger, an open-source visualization tool.
To install Jaeger, you can use Docker with this command:
docker run -d --name jaeger \
-e COLLECTOR_ZIPKIN_HOST_PORT=:9412 \
-p 16686:16686 \
-p 9412:9412 \
jaegertracing/all-in-one:1.22
This command starts a Jaeger instance with the all-in-one image, which includes the collector, query, and agent components.
After installation, configure Jaeger to connect with your tracing infrastructure. You can use a configuration file or environment variables.
For example, create a jaeger.yaml file with this content:
collector:
zipkin:
host_port: ":9412"
This configuration sets up the collector to listen on port 9412 for Zipkin traces.
To integrate Jaeger with your existing tracing setup, configure your application to send traces to Jaeger. This involves instrumenting your application with a tracing library, such as OpenTelemetry or OpenTracing.
For example, you can use the OpenTelemetry Java agent to instrument your Java application:
pom.xml file:<dependency>
<groupId>io.opentelemetry</groupId>
<artifactId>opentelemetry-javaagent</artifactId>
<version>1.22.0</version>
</dependency>
import io.opentelemetry.javaagent.OpenTelemetryJavaAgent;
public class MyApplication {
public static void main(String[] args) {
OpenTelemetryJavaAgent.init("jaeger", "http://localhost:9412/api/v2/spans");
//...
}
}
During setup, you may encounter issues such as connection errors, data loss, or performance problems. To troubleshoot these issues, you can use Jaeger's built-in debugging tools, such as the query component's debug endpoint.
For example, use this command to check the query component's debug endpoint:
curl http://localhost:16686/debug/vars
This command returns a list of debug variables, including the number of traces received and the number of errors encountered.
A typical distributed tracing interface has these main parts:
When looking at traces, pay attention to:
To find specific issues or events in a trace, you can:
| Navigation Technique | Description |
|---|---|
| Zooming and Panning | Use the timeline view to zoom in on specific time ranges or pan across the trace to explore different segments. |
| Filtering by Service | Isolate specific services or components to analyze their behavior and dependencies. |
| Filtering by Error | Focus on error spans to identify and troubleshoot issues quickly. |
Analyzing distributed traces helps you understand how your distributed systems perform and identify issues. Here are some strategies for effective trace analysis:
To optimize system performance, identify bottlenecks and latency issues:
Correlating trace data with logs and metrics provides a comprehensive view of system performance:
| Technique | Description |
|---|---|
| Log Correlation | Correlate trace data with log data for deeper insights into system behavior. |
| Metric Correlation | Correlate trace data with metric data to identify performance trends and patterns. |
| Service Dependency Analysis | Analyze how services interact and impact system performance. |
Distributed tracing tools allow you to see how different parts of your system interact through visual dependency maps or service maps. These maps show the relationships and connections between services and components, helping you identify potential bottlenecks or performance issues.
For example, Lightstep's Service Diagram provides a live visual representation of your services and their dependencies. This helps you understand the complexity of your system, spot areas for improvement, and investigate the root causes of problems.
In addition to dependency maps, many tools offer ways to analyze and visualize how services interact. This can help you identify potential points of failure or performance bottlenecks caused by specific services or components.
Datadog's Service Map, for instance, shows a visual representation of your services and their relationships. You can drill down into individual services to see detailed metrics and trace data.
Most distributed tracing tools allow you to customize the visualization experience to suit your needs. This might include creating custom dashboards, defining alert conditions, or configuring the level of detail displayed.
For example, Site24x7's APM allows you to create custom transaction monitors and set thresholds for performance metrics. You can then generate detailed reports and set up alerts when thresholds are breached.
Many tools also provide APIs or SDKs that allow you to integrate the visualization capabilities into your own applications or build custom visualizations tailored to your specific requirements.
| Customization Option | Description |
|---|---|
| Custom Dashboards | Create dashboards tailored to your specific monitoring needs. |
| Alert Conditions | Define conditions to trigger alerts for performance issues. |
| Detail Level | Configure the level of detail displayed in visualizations. |
| APIs and SDKs | Integrate visualization capabilities into your own applications. |
Distributed tracing provides insights into how your complex systems perform. However, to get the most out of it, you need to integrate it with other monitoring tools. This section explores ways to combine distributed trace visualization with other tools, correlate traces with logs and metrics for comprehensive monitoring, and how this integration can enhance troubleshooting and optimization.
You can integrate distributed tracing tools with other monitoring tools in several ways:
Integrating distributed tracing with other monitoring tools offers these advantages:
Here are examples of how integrated monitoring setups have improved troubleshooting and system performance:
