# Sentry OTel Repro
Based on a convo me and @AbhiPrasad had a few days ago. This repo provides 2 endpoint: `/fast` which just do
a fizzbuzz loop from 0 to 100, and `/slow` which makes tons of outgoing HTTP call.
Set your `SENTRY_DSN` as an environment variable.
On Linux: `export SENTRY_DSN=https://....ingest.sentry.io/123`
On Windows: `$env:SENTRY_DSN="https://....ingest.sentry.io/123"`
## Run steps
1. `pnpm install`
2. `cd tracing-otel && pnpm run start`, then it should be running at `localhost:3000`
```http
GET http://localhost:3000/slow
```
```http
GET http://localhost:3000/fast
```
3. `cd tracing-sentry && pnpm run start`, then it should be running at `localhost:5000`
```http
GET http://localhost:5000/slow
```
```http
GET http://localhost:5000/fast
```
Or if you have [k6](https://k6.io/) ready:
1. `cd benchmark`
2. `k6 run otel-fast.js`
3. `k6 run sentry-fast.js`
4. `k6 run otel-slow.js`
5. `k6 run sentry-slow.js`
## Benchmark Results
