OpenTelemetry integration

Example

// Minimal setup – environment variables must be set before import.
process.env.OTEL_SERVICE_NAME = 'my-app';
process.env.OTEL_TRACES_SAMPLER = 'always_on';
process.env.OTEL_TRACES_SAMPLER_ARG = '1';
process.env.OTEL_EXPORTER_OTLP_ENDPOINT = 'http://localhost:4317';
process.env.OTEL_SPAN_PROCESSOR = 'batch'; // 'batch' (default) | 'simple' | 'console'

import { scope, span } from '@biorate/opentelemetry';

@scope('1.0')
class Service {
  @span({ exclude: ['arguments.0.password', 'result.token'] })
  public authenticate(credentials: { password: string; login: string }) {
    return { token: 'jwt...', user: { id: 1 } };
  }
}

const svc = new Service();
svc.authenticate({ password: 'secret', login: 'admin' });
// span.arguments → '[{"login":"admin"}]' (password excluded)
// span.result    → '{"user":{"id":1}}'       (token excluded)

Span processor tuning (optional, defaults shown):

• OTEL_SPAN_PROCESSOR=batch|simple|console (default batch; unknown/empty values fall back to batch)
• OTEL_BSP_SCHEDULE_DELAY=5000, OTEL_BSP_MAX_QUEUE_SIZE=2048
• OTEL_BSP_MAX_EXPORT_BATCH_SIZE=512, OTEL_BSP_EXPORT_TIMEOUT=30000
• OTEL_SPAN_ATTR_MAX_LENGTH=2048 truncates string span attributes.
