## Tracing
|
|
|
|
Run the app with the OpenTelemetry tracing.
|
|
|
|
```
|
|
npm run start -- --tracing
|
|
# or
|
|
npm run start-dev -- --tracing
|
|
```
|
|
|
|
Manually:
|
|
|
|
```
|
|
node --require './server/tracing.js' server/server.js
|
|
```
|
|
|

Traces are made up of many spans. Each span defines a `traceId` which it is associated with.
|
|
|
|
