Elasticsearch (). Ping () отображает ошибки из urllib3, если сервер не работает

У меня есть ожидание Elasticsearch.ping: должно возвращаться True, если можно связаться с Elasticsearch, и False, если это невозможно.Однако, если соединение не может быть установлено, ping покажет кучу ошибок, прежде чем окончательно вернет False.Есть ли способ предотвратить это?Мне действительно все это не нужно, я просто хочу свои False.

Похоже на ошибку, с которой столкнулись некоторые люди: https://github.com/elastic/elasticsearch-py/issues/666

, чтобы подвести итог вышеприведенному обсуждению, попытайтесь подавить регистратор в упругом поиске только для регистрации ошибок, например: 

import logging
logging.basicConfig(level=logging.ERROR)

и посмотрите, поможет ли это вам.

РЕДАКТИРОВАТЬ: ОП исправила проблему, более конкретно: elasticsearch с помощью: 

import logging; 
logging.getLogger('elasticsearch').level = logging.ERROR

оба способа работают.
