我正在GCP中运行 Couchdb 2.1.1 ，并希望在Stackdriver中设置对CouchDB集群的监视。 CouchDB的现有 Stackdriver 插件不再起作用（已弃用）。
我已经尝试了多种方法来尝试解决此问题，包括尝试更新不建议使用的配置文件，但是我在系统日志中会得到我不确定如何解释的错误。
下面是一个配置文件，我仅用于使一个统计信息出现在Stackdriver中：
# This is the monitoring configuration for CouchDB.
# Look for COUCHDB_HOST and COUCHDB_PORT to adjust your configuration file.
LoadPlugin curl_json
<Plugin "curl_json">
<URL "http://localhost:5986/_stats">
Instance "couchdb"
User "foo"
Password "XXX"
<Key "couchdb/httpd/requests/value">

</Key>
</URL>
</Plugin>
LoadPlugin match_regex

这是我在系统日志中看到的错误：

有人可以帮忙弄清楚为什么这个配置文件不起作用吗？
