docker-otel-lgtm

grafana/otel-lgtm bundles Grafana's open source stack for OpenTelemetry monitoring in a single Docker image.

Intended Usage

The intended usage is:

• Quick way to try OSS Grafana with OpenTelemetry.
• Demos, presentations.
• Integration tests for OpenTelemetry instrumentation: Run automated queries against the databases to check if expected metrics/traces/logs are present.

The Docker image is not intended for production monitoring.

Get the Docker image

The Docker image is available on Docker hub: https://hub.docker.com/r/grafana/otel-lgtm

Run the Docker image

./run-lgtm.sh

Send OpenTelemetry Data

There's no need to configure anything: The Docker image works with OpenTelemetry's defaults.

# Not needed as these are the defaults in OpenTelemetry:
export OTEL_EXPORTER_OTLP_PROTOCOL=grpc
export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317

View Grafana

Log in to http://localhost:3000 with user admin and password admin.

Build the Docker image from scratch

cd docker/
docker build . -t grafana/otel-lgtm

Build and run the example app

Run the example REST service:

./run-example.sh

Generate traffic:

./generate-traffic.sh

Run example apps in different languages

The example apps are in the examples/ directory. Each example has a run.sh script to start the app.

Every example implements a rolldice service, which returns a random number between 1 and 6.

Each example uses a different application port (to be able to run all applications at the same time).

Example	Service URL
Java	curl http://localhost:8080/rolldice
Go	curl http://localhost:8081/rolldice
Python	curl http://localhost:8082/rolldice
