```{index} graylog, препрод
```


# Автоматическое включение заглушки для graylog (на препроде)

Настроено на препроде на `с07-nginx01`.

Скрипт выбирает все файлы `*graylog*.conf` из `/etc/nginx/conf.d/` и создаёт
для них соответствующие флаги `.maintenance` в `/tmp/ramdisk`.

```{attention}
Cкрипт не будет работать корректно, если в именах файлов встретятся пробелы или
символы переноса строки!
```
