Crate polkadot_node_jaeger

Polkadot Jaeger related primitives

Provides primitives used by Polkadot for interfacing with Jaeger.

Integration

See https://www.jaegertracing.io/ for an introduction.

The easiest way to try Jaeger is:

• Start a docker container with the all-in-one docker image (see below).
• Open your browser and navigate to https://localhost:16686 to access the UI.

The all-in-one image can be started with:

podman login docker.io
podman run -d --name jaeger \
 -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
 -p 5775:5775/udp \
 -p 6831:6831/udp \
 -p 6832:6832/udp \
 -p 5778:5778 \
 -p 16686:16686 \
 -p 14268:14268 \
 -p 14250:14250 \
 -p 9411:9411 \

Enums

Jaeger

Stateful convenience wrapper around mick_jaeger.

JaegerError

A description of an error during jaeger initialization.

Span

Stage

A helper to annotate the stage with a numerical value to ease the life of the tooling team creating viable statistical metrics for which stage of the inclusion pipeline drops a significant amount of candidates, statistically speaking.

Functions

hash_to_trace_identifier

A helper to convert the hash to the fixed size representation needed for jaeger.
