# Open Telemetery Example
|
|
|
|
## Example Usage
|
|
|
|
Use the _code block_ widget to start and end spans. Spans can be nested to form a stack, ending a span will always end the last span added to the stack.
|
|
|
|
### Visualization
|
|
|
|
For example, using Jaeger UI:

|
|
|
|
### Start Span
|
|
|
|
```javascript
|
|
(async () => {
|
|
opentelemetry.startSpan("Global Flow")
|
|
})()
|
|
.catch((error) => {
|
|
console.error(error.message)
|
|
recognizedObject.answers.push('')
|
|
recognizedObject.errorInfo = {
|
|
...recognizedObject.errorInfo,
|
|
label: {
|
|
data: error.toJSON ? error.toJSON() : {},
|
|
message: error.message,
|
|
},
|
|
}
|
|
})
|
|
.finally(() => {
|
|
next()
|
|
})
|
|
|
|
```
|
|
|
|
### End Span
|
|
|
|
```javascript
|
|
(async () => {
|
|
opentelemetry.endSpan("Global Flow")
|
|
})()
|
|
.catch((error) => {
|
|
console.error(error.message)
|
|
recognizedObject.answers.push('')
|
|
recognizedObject.errorInfo = {
|
|
...recognizedObject.errorInfo,
|
|
label: {
|
|
data: error.toJSON ? error.toJSON() : {},
|
|
message: error.message,
|
|
},
|
|
}
|
|
})
|
|
.finally(() => {
|
|
next()
|
|
})
|
|
|
|
``` |
