# Example
|
|
|
|
## HTTP
|
|
This is a simple example that demonstrates tracing http request from client to server. The example
|
|
shows key aspects of tracing such as:
|
|
|
|
- Root Span (on Client)
|
|
- Child Span (on Client)
|
|
- Child Span from a Remote Parent (on Server)
|
|
- SpanContext Propagation (from Client to Server)
|
|
- Span Events
|
|
- Span Attributes
|
|
|
|
Example uses
|
|
- open-telemetry SDK as trace instrumentation provider,
|
|
- httptrace plugin to facilitate tracing http request on client and server
|
|
- http trace_context propagation to propagate SpanContext on the wire.
|
|
- stdout exporter to print information about spans in the terminal
|
|
|
|
### How to run?

|
|
|
#### Prequisites

#### 3 Start Client
|
|
```
