Я использую Couchdb 2.1.1 в GCP и собираюсь настроить мониторинг нашего кластера CouchDB в Stackdriver. Существующий плагин Stackdriver для CouchDB больше не работает (и устарел).
Я пробовал много разных способов решить эту проблему, в том числе обновить устаревший файл конфигурации, но в системном журнале я получал ошибки, которые я не знал, как их интерпретировать.
Ниже приведен файл конфигурации, который я использую только для того, чтобы одна статистика появилась в Stackdriver:
# This is the monitoring configuration for CouchDB.
# Look for COUCHDB_HOST and COUCHDB_PORT to adjust your configuration file.

Это ошибка, которую я вижу в системном журнале:

Может кто-нибудь помочь выяснить, почему этот конфигурационный файл не работает?
