We host an OpenTelemetry collector endpoint at https://otel.highlight.io:4318/v1/traces and https://otel.highlight.io:4318/v1/logs. Configure your OpenTelemetry SDK to send logs via OTLP HTTPS to this endpoint. Your Highlight Project ID should be included as an attribute with the highlight.project_id key. This configuration will depend on which SDK you use in your app.

import { NodeSDK } from '@opentelemetry/sdk-node'
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-http';
import { Resource } from '@opentelemetry/resources'
import type { Attributes } from '@opentelemetry/api'

const attributes: Attributes = {
	// Provide the highlight project ID as a resource attribute or via the exporter headers
    'highlight.project_id': '<YOUR_PROJECT_ID>'
}
const sdk = new NodeSDK({
	resource: new Resource(attributes),
	traceExporter: new OTLPTraceExporter({
		// NB: this is the url for trace exports. if you are using a language which supports
		// the opentelemetry logs format, use 'https://otel.highlight.io:4318/v1/logs'
		url: 'https://otel.highlight.io:4318/v1/traces'
		// In some OpenTelemetry implementations, it's easier to provide 
		// the project ID as a header rather than a resource attribute.
		// headers: { 'x-highlight-project': '<YOUR_PROJECT_ID>' }
	})
});
const tracer = trace.getTracer('my-service');
sdk.start();

const log = (level: string, message: string) => {
    const span = tracer.startSpan('main')
    span.setAttributes({ 
    	['highlight.session_id']: 'abc123',
    	['highlight.trace_id']: 'def456',
    	customer: 'vadim',
    	customer_id: 1234
    })
    
    span.addEvent('log', {
	    ['log.severity']: level,
	    ['log.message']: message
	}, new Date())
    span.end()
};

log('info', 'hello, world!')
