The Rust OpenTelemetry implementation.
Website | Chat | Documentation
OpenTelemetry is a collection of tools, APIs, and SDKs used to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) for analysis in order to understand your software's performance and behavior. You can export and analyze them using [Prometheus], [Jaeger], and other observability tools.
Compiler support: requires rustc 1.46+
```rust use opentelemetry::{global, sdk::export::trace::stdout, trace::Tracer};
fn main() { // Create a new trace pipeline that prints to stdout let tracer = stdout::newpipeline().installsimple();
tracer.in_span("doing_work", |cx| {
// Traced app logic here...
});
// Shutdown trace pipeline
global::shutdown_tracer_provider();
} ```
See the examples directory for different integration patterns.
In addition to opentelemetry, the [open-telemetry/opentelemetry-rust]
repository contains several additional crates designed to be used with the
opentelemetry ecosystem. This includes a collection of trace SpanExporter
and metrics pull and push controller implementations, as well as utility and
adapter crates to assist in propagating state and instrumenting applications.
In particular, the following crates are likely to be of interest:
opentelemetry-aws] provides unofficial propagators for AWS X-ray.opentelemetry-contrib] provides additional exporters and propagators that
are experimental.opentelemetry-datadog] provides additional exporters to [Datadog].opentelemetry-dynatrace] provides additional exporters to [Dynatrace].opentelemetry-http] provides an interface for injecting and extracting
trace information from [http] headers.opentelemetry-jaeger] provides a pipeline and exporter for sending trace
information to [Jaeger].opentelemetry-otlp] exporter for sending trace and metric data in the OTLP
format to the OpenTelemetry collector.opentelemetry-prometheus] provides a pipeline and exporter for sending
metrics information to [Prometheus].opentelemetry-semantic-conventions] provides standard names and semantic
otel conventions.opentelemetry-stackdriver] provides an exporter for Google's [Cloud Trace]
(which used to be called StackDriver).opentelemetry-zipkin] provides a pipeline and exporter for sending trace
information to [Zipkin].Additionally, there are also several third-party crates which are not
maintained by the opentelemetry project. These include:
tracing-opentelemetry] provides integration for applications instrumented
using the [tracing] API and ecosystem.actix-web-opentelemetry] provides integration for the [actix-web] web
server and ecosystem.opentelemetry-application-insights] provides an unofficial [Azure
Application Insights] exporter.opentelemetry-tide] provides integration for the [Tide] web server and
ecosystem.If you're the maintainer of an opentelemetry ecosystem crate not listed
above, please let us know! We'd love to add your project to the list!
OpenTelemetry is built against the latest stable release. The minimum supported version is 1.46. The current OpenTelemetry version is not guaranteed to build on Rust versions earlier than the minimum supported version.
The current stable Rust compiler and the three most recent minor versions before it will always be supported. For example, if the current stable compiler version is 1.49, the minimum supported version will not be increased past 1.46, three minor versions prior. Increasing the minimum supported compiler version is not considered a semver breaking change as long as doing so complies with this policy.
