Logging

Logging is supported by exporting a custom logger for the std/log module.

Example usage:

import * as log from 'https://deno.land/std@0.203.0/log/mod.ts';
import { OpenTelemetryHandler } from 'npm:@hyperdx/deno';

log.setup({
  handlers: {
    otel: new OpenTelemetryHandler('DEBUG'),
  },

  loggers: {
    'my-otel-logger': {
      level: 'DEBUG',
      handlers: ['otel'],
    },
  },
});

log.getLogger('my-otel-logger').info('Hello from Deno!');
