check-traces-manual

Same as https://github.com/obs-nebula/check-traces, but using manual instrumentation.

OTEL-JS packages in use:

Package
@opentelemetry/exporter-trace-otlp-http	To export to OTELCOL via OTLP/HTTP
@opentelemetry/resources	To be used with semantic-conventions to identify the application/service's name
@opentelemetry/sdk-trace-base	For manual instrumentation
@opentelemetry/semantic-conventions	To be used with resources to identify the application/service's name
@opentelemetry/api	To get the trace instance and control spans creation

How to run

# This will download and start OTELCOL
./scripts/start.sh

# Start the example
npm install
npm run build
npm start

Test

# Create some spans
curl -v http://localhost:8080
# Check the results
curl -s http://localhost:8888/metrics

Stop the application and OTELCOL

killall node
./scripts/stop.sh
