# Deno

本指南涵盖以下集成：

* **日志**

<Note>
  当前仅支持 OpenTelemetry 日志。如需链路追踪支持，[请参阅以下指南](https://dev.to/grunet/leveraging-opentelemetry-in-deno-45bj#a-minimal-interesting-example)。
</Note>

<div id="logging">
  ## 日志
</div>

可通过为 `std/log` 模块导出自定义日志记录器来启用日志功能。

**示例用法：**

```typescript theme={null}
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!');
```
