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.

If you are looking for an production-ready out-of-the box solution to monitor applications and minimize MTTR (mean time to resolution) with OpenTelemetry and Prometheus try Grafana Cloud Application Observability.

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
