Example Infrastructure watched via OpenTelemetry

Requirements

• prepared (clean) Elastic stack: ElasticSearch + APM + Kibana
• Running OpenTelemetry collector
• Install Node / NPM / JAVA (11+) / PostgreSQL
• Installed Example Projects

Build demo

• Install NX npm i -g nx
• Initialize project npm i
• Build angular / node API npm i
• Build JAVA API nx run java-api:buildJar

Step to start demo

• install project (npm i)

• start angular app nx run angular-app:serve

• start node API OTEL_SERVICE_NAME=example-security-gateway nx run node-api:serve

• start java API java -javaagent:opentelemetry-javaagent-all.jar -Dotel.resource.attributes=service.name=example-core-api -Dotel.traces.exporter=otlp -jar build/libs/example-projects-0.0.1-SNAPSHOT.jar (can be also run without OpenTelemetry agent nx run java-api:serve)

• start local OpenTelemetry collector

• start ElasticSearch / Kibana / APM

How to run local OpenTelemetry collector

• export GOROOT=/opt/repo/opentelemetry/go
• export PATH=$GOROOT/bin:$PATH
• export PATH=$PATH:$(go env GOPATH)/bin
• ./bin/otelcol_$(go env GOOS)_$(go env GOARCH) --config ./examples/local/lambda-config.yaml;

How to configure/build OpenTelemetry collector

TODO

NGrok

To enable hosted applications (not localhost, for example lambda) to be able to send data to locally stared OpenTelemetry collector can be used ngrok.

• download ngrok
• start ngrok ./ngrok tcp 8200
