## appsettings.json

```json
{
  "Logging": {
    "Serilog": {
      "Elasticsearch": {
        "IndexFormat": "logstash-{0:yyyy.MM.dd}"
      }
    }
  }
}
```

## Important Notes

The IndexFormat configuration must be consistent between your Serilog settings and this module's configuration to ensure proper log retrieval. The default format is "logstash-{0:yyyy.MM.dd}".
