Actix Web Observability with TraceKit
TraceKit works with any OpenTelemetry-compatible application -- including Actix Web. Point your Rust OTel SDK at TraceKit's OTLP endpoint and get distributed tracing, session replay, and alerts for your high-performance Rust services.
Actix observability challenges
Common problems that Actix developers face in production -- and how TraceKit solves them.
Actor System Message Tracing
Actix's actor model processes messages asynchronously across isolated actors. When a request triggers a chain of actor messages, the execution path becomes invisible without distributed tracing. TraceKit via OpenTelemetry traces message flow across actor boundaries so you can see the full request lifecycle.
Handler Extraction Pipeline
Actix Web handlers use extractor chains (Path, Query, Json, Data) that can fail silently or add unexpected latency. When a multi-extractor handler returns a 400, which extractor failed? TraceKit traces the extraction pipeline so you can pinpoint exactly where requests break down.
Async Move Closures Losing Context
Rust's ownership model means async move closures can lose trace context when values are moved into new tasks. The borrow checker ensures memory safety but does not guarantee trace continuity. TraceKit's OpenTelemetry integration propagates context across async boundaries in Rust.
Get started in minutes
Add OpenTelemetry instrumentation to your Actix app with a few lines of code.
// Cargo.toml
// opentelemetry = "0.22"
// opentelemetry-otlp = "0.15"
// actix-web-opentelemetry = "0.16"
use actix_web::{web, App, HttpServer};
use actix_web_opentelemetry::RequestTracing;
use opentelemetry_otlp::WithExportConfig;
let exporter = opentelemetry_otlp::new_exporter()
.tonic()
.with_endpoint("https://otel.tracekit.dev:4317");
HttpServer::new(|| {
App::new()
.wrap(RequestTracing::new())
.route("/", web::get().to(index))
})What you get with TraceKit
Distributed Tracing
Trace requests across Actix Web handlers, actor messages, and database queries. Full visibility into your Rust application's request lifecycle via OpenTelemetry.
Live Code Monitoring
Monitor your Actix Web services in real time. Track request latency, error rates, and throughput with TraceKit's dashboard -- no Rust-specific SDK required.
Simple Pricing
$29/month flat for your entire Rust service. No per-thread fees, no per-actor charges -- one price for full observability of your high-performance application.
