tracegen

A utility tool capable of generating OpenTelemetry traces. It can work in two modes:

• cli
• http server

Both modes generates traces and send them to http://localhost:4317 (you can override this by passing the option -c <your-collector-endpoint

Options

flag	shortcut	default	description
-c	--collector	localhost:4317	OpenTelemetry collector gRPC endpoint where the traces will be sent to
-s	--services	1	number of fake services used to generate the trace
-n	--spans	10	approximated number of spans you want to generate. Each service will have (spans / services) spans
	--tracestate		list of values injected into the tracestate of each trace

Run modes

CLI

Generates a single trace every time you run it.

tracegen -s 10 -n 30 start

HTTP Server

Creates an HTTP Server that generates a new server everytimes the endpoint GET / is called.

tracegen -s 10 -n 30 -p 9095 serve

In this mode, there's an extra option: --port or -p which specifies the number of the port that will be used by the web server

Configuring the collector

If you pass the option --collector <endpoint> tracegen will connect to this gRPC endpoint and send traces there using the OpenTelemetry Protocol.
