# grove.log()

## Signature

```ts
grove.log(message: string, level?: 'log' | 'info' | 'warn' | 'error' | 'debug'): void
```

## Availability

All packaged runtimes. No capability required.

## Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| `message` | Yes | Diagnostic text. The facade converts it with String. |
| `level` | No | Exact lower-case level; omitted or unknown values use log. |

## Return value

Returns `undefined`.

## Behavior and errors

Mango attributes output to the running instance in its local and global Grove consoles. Standard console methods and uncaught JavaScript errors are also captured. Keep tokens, keys, message bodies, and private response payloads out of diagnostics. This method provides no persistence or delivery acknowledgement.

## Example

```js
try {
  await grove.secrets.application.get('service-token')
} catch {
  grove.log('Could not read the service credential.', 'error')
}
```
