Native OpenTelemetry Logging
Learn how to export logs to highlight.io via one of the OpenTelemetry SDKs.
1
Export your logs to the highlight.io collector.
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 = {
'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'
})
});
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!')

Verify your backend logs are being recorded.
Visit the highlight logs portal and check that backend logs are coming in.
