opentelemetry-tide
[OpenTelemetry] integration for [Tide]
Add OpenTelemetry tracing and metrics support to your tide application.
Be part of the new observability movement!
## Notes
* It only implements very basic request tracing on the middleware layer.
If you need spans for your executed code, you need to add them yourself.
* It provides basic prometheus metrics, based on the [RED method].
* This project got inspired by .
* You probably do not want to use it in production. 🤷
## How to use
```sh
# Run jaeger in background
docker run -d \
-p6831:6831/udp -p6832:6832/udp -p16686:16686 -p14268:14268 \
jaegertracing/all-in-one:latest
# Run server example with tracing middleware
cargo run --example server
# Make a request or two ...
curl http://localhost:3000/
# Open browser and view the traces
firefox http://localhost:16686/
# Check the prometheus metrics endpoint
curl http://localhost:3000/metrics
```
## Example
### `Cargo.toml`
```toml
# ...
[dependencies]
async-std = { version = "1.10", features = ["attributes"] }
opentelemetry = { version = "0.17.0", features = ["rt-async-std"] }
opentelemetry-jaeger = { version = "0.16.0", features = ["rt-async-std"] }
opentelemetry-tide = "0.12"
tide = "0.16"
```
### `server.rs`
```rust
use opentelemetry::{global, KeyValue, runtime};
use opentelemetry_semantic_conventions::resource;
use opentelemetry_tide::TideExt; // import trait
const VERSION: &'static str = env!("CARGO_PKG_VERSION");
#[async_std::main]
async fn main() -> Result<(), Box> {
tide::log::with_level(tide::log::LevelFilter::Warn);
let tags = [resource::SERVICE_VERSION.string(VERSION)];
let _tracer = opentelemetry_jaeger::new_pipeline()
.with_tags(tags.iter().map(ToOwned::to_owned))
.install_batch(runtime::AsyncStd)
.expect("pipeline install failure");
let tracer = global::tracer("example-server");
let metrics_kvs = vec![KeyValue::new("K", "V")];
let mut app = tide::new();
// use the trait
app.with_middlewares(tracer, Some(metrics_kvs));
app.at("/").get(|_| async move {
Ok("Hello, OpenTelemetry!")
});
app.listen("0.0.0.0:3000").await?;
global::shutdown_tracer_provider();
Ok(())
}
```
