gRPC distributed tracing

Helios' instrumentation of gRPC enables developers to visualize and troubleshoot their applicative flows that utilize gRPC.

Below are a few examples of how to leverage E2E observability in Helios when using gRPC to communicate across your microservices.

Tracing & visualization

A gRPC endpoint will show as an observed gRPC method call in a specific service. For example, the following operations consist of 3 different methods calls in 2 distinct services:

Payload is also available (on client operations) as request and response body:


Helios is a a dev-first observability platform that helps dev and ops teams shorten the time to find and fix issues in distributed applications. Built on OpenTelemetry, Helios provides traces and correlates them with logs and metrics, enabling end-to-end app visibility and faster troubleshooting.
