What is @opentelemetry/exporter-zipkin?
The @opentelemetry/exporter-zipkin package is designed for Node.js and web applications to export telemetry data to Zipkin, a distributed tracing system. It allows developers to monitor and troubleshoot their applications by collecting and reporting timing data needed to troubleshoot latency problems in microservice architectures. This package is part of the OpenTelemetry project, which provides a set of APIs, libraries, agents, and instrumentation to create and manage telemetry data (metrics, logs, and traces).
What are @opentelemetry/exporter-zipkin's main functionalities?
Exporting Traces to Zipkin
This code snippet demonstrates how to set up the ZipkinExporter with the OpenTelemetry Node.js SDK. It initializes a NodeTracerProvider, configures the ZipkinExporter with the service name and Zipkin server URL, and registers the exporter using a SimpleSpanProcessor.
{
const { ZipkinExporter } = require('@opentelemetry/exporter-zipkin');
const { SimpleSpanProcessor } = require('@opentelemetry/tracing');
const { NodeTracerProvider } = require('@opentelemetry/node');
const provider = new NodeTracerProvider();
const zipkinExporter = new ZipkinExporter({
serviceName: 'your-service-name',
url: 'http://localhost:9411/api/v2/spans'
});
provider.addSpanProcessor(new SimpleSpanProcessor(zipkinExporter));
provider.register();
}
Other packages similar to @opentelemetry/exporter-zipkin
@opentelemetry/exporter-jaeger
Similar to the Zipkin exporter, the Jaeger exporter allows exporting traces to Jaeger, another open-source, end-to-end distributed tracing system. It provides functionality to send telemetry data to a Jaeger backend, facilitating the monitoring and troubleshooting of microservices-based distributed systems. The choice between Zipkin and Jaeger often depends on the specific needs of the project and the existing infrastructure.
@opentelemetry/exporter-prometheus
While not directly similar in terms of exporting traces, the Prometheus exporter is another telemetry data exporter that focuses on metrics. It allows exporting metrics data to a Prometheus monitoring system. This package is useful for users who are looking to monitor their application's performance and health through metrics rather than tracing data. It complements the functionality provided by the Zipkin exporter by offering a different aspect of telemetry data monitoring.
OpenTelemetry Zipkin Trace Exporter
OpenTelemetry Zipkin Trace Exporter allows the user to send collected traces to Zipkin.
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in microservice architectures. It manages both the collection and lookup of this data.
Installation
npm install --save @opentelemetry/exporter-zipkin
Usage
Install the exporter on your application and pass the options, it must contain a service name.
const { ZipkinExporter } = require('@opentelemetry/exporter-zipkin');
const options = {
url: 'your-zipkin-url',
serviceName: 'your-application-name'
}
const exporter = new ZipkinExporter(options);
Now, register the exporter and start tracing.
tracer.addSpanProcessor(new BatchSpanProcessor(exporter));
You can use built-in SimpleSpanProcessor
or BatchSpanProcessor
or write your own.
- SimpleSpanProcessor: The implementation of
SpanProcessor
that passes ended span directly to the configured SpanExporter
. - BatchSpanProcessor: The implementation of the
SpanProcessor
that batches ended spans and pushes them to the configured SpanExporter
. It is recommended to use this SpanProcessor
for better performance and optimization.
