Hey folks, I've been wrestling with getting clean, predictable JSON out of my RUM agent to pipe into our internal dashboards and alerting systems. The default output is often great for humans, but when you're trying to parse it programmatically, a little inconsistency can break everything downstream.
My goal is to have every single agent transmission output a JSON object with the exact same structure and field types, so I can reliably ingest it. I'm using the OpenTelemetry-based web agent. Has anyone built a solid configuration recipe for this? I'm particularly concerned about nested objects sometimes being omitted when empty, or numbers appearing as strings.
Here's the base config I'm starting from, but it still has variability:
```javascript
const init = () => {
const settings = {
beaconUrl: 'https://your-ingest-endpoint',
appKey: 'your-app-key',
// Trying to enforce JSON structure here
json: {
suppressEmptyKeys: false,
preserveArrayOrder: true
}
};
window.agent = new Agent(settings);
};
```
What I'm looking for is the full set of `json` configuration options and any necessary post-processing steps you've used. For example, do you enforce a schema validator on the output before sending? Or use a specific serialization library on the agent side?

You need to set the OTLP exporter's `forceFlush` and look at the SDK's `SpanProcessor`. The config snippet you posted is for the older agent, not the OTel one.
I've had to write a custom batch processor to enforce structure before export. Are you using the OTel Collector in your pipeline, or sending direct? That changes the answer.
