## Name

The plug-in can automatically rotate access and error log files in the log directory at regular intervals.

Specify how often logs are rotated every interval and how many logs have been kept recently.
When the number of log files exceeds the remaining number, the old files are automatically deleted.

## Attributes

| Name     | Type    | Requirement | Default | Valid | Description                                                                                                          |
| -------- | ------- | ----------- | ------- | ----- | -------------------------------------------------------------------------------------------------------------------- |
| interval | integer | required    | 60 * 60 |       | How often to rotate the log in seconds                                                                               |
| max_kept | integer | required    | 24 * 7  |       | How many historical logs can be kept at most. When this number is exceeded, old files will be deleted automatically. |

After this plug-in is enabled, the log file will be automatically rotated according to the configuration.
For example, the following example is a sample based on `interval: 10` and `max_kept: 10`.

```shell
$ ll logs

### Example

#### Enable plugin

Enable the plug-in `log-rotate` in `conf/config.yaml`, then this plugin can work fine.
It does not need to be bound in any route or service.

Here is an example of `conf/config.yaml`:

```yaml
plugins:
    # the plugins you enabled
    - log-rotate

plugin_attr:
    log-rotate:
        interval: 3600    # rotate interval (unit: second)
        max_kept: 168     # max number of log files will be kept
```

#### Disable plugin

Remove the plugin `log-rotate` from `conf/config.yaml`.
