Zabbix Сервер не получает данные от самого себя (127.0.0.1)

[OWLSLY]

Добрый день! Не знаю, как более правильно сформулировать данный вопрос. поэтому пока так.

Есть Zabbix Server 5.0.20 на CentOS 8 + MySQL. Работает исправно, мониторит, пока что, все наши сетевые устройства. Как известно, при установке Zabbix сервера по умолчанию создаётся хост Zabbix server с агентом 127.0.0.1 и он занимается "самомониторингом". Вот у меня этот "самомониторинг" не работает, ни в последних данных ни в графиках ничего нет. Я не очень понимаю, куда смотреть, так как в конфиге агента всё корректно, в конфиге сервера тоже, ошибок в логе агента не вижу и в логе сервера, помимо известных для меня "не найденных" хостов тоже нет ошибок. Подскажите, куда копать и куда смотреть. По запросу дам данные с выводом необходимой информации.

Насколько я понял, хост с именем "Zabbix server" в веб-интерфейсе Zabbix присутствует.
А определены ли для него какие-то метрики, т.е. элементы данных (Items)? Обычно они наследуются от шаблона "Template App Zabbix Server", он у вас привязан к этому хосту?

Для хоста не определены элементы данных. Вот что я вижу внутри.

Проверил шаблоны, которые присоединены к хосту - они пустые, там нет ничего внутри. Не знаю, как такое могло произойти. Может есть где-то дефолтные эти шаблоны, где их можно скачать?

Скачать можно где-то здесь (ссылка раз и ссылка два).
Заходите в нужную папку (например, "zabbix_server"), затем слева вверху (под словом "Source") выбираете нужную ветку: вместо "master" (которая указана по умолчанию) нужно выбрать релиз для вашей версии (например, "release/5.0"). И тогда уже можно скачивать и затем импортировать шаблон.

Спасибо Вам огромное. Помогло удаление старых и добавление новых шаблонов. Добра и мира Вам!)
