如何在Openstack rocky上使用Gnocchi API

Question

我正在尝试使用gnocchi API来读取度量数据。

所以我安装了Openstack和devstack(我附加了一个配置文件(local.conf) )。我想我安装了ceilometer和gnocchi来收集数据。但是当我尝试读取API服务器和CLI上的数据时，它不起作用。你能解释一下为什么它不工作吗？

命令'openstack指标列表‘运行良好，但'gnocchi指标列表’根本不起作用。下面的消息。

无法建立与http://localhost:8041/v1/metric的连接？：HTTPConnectionPool(host='localhost'，port=8041)：超过了url: /v1/http://localhost:8041/v1/metric的最大重试次数(由NewConnectionError引起(‘：无法建立新连接: Errno 111连接被拒绝’，))

另外，当我发布带有X-Auth-Token的https://localhost/metric/v1/metric (这是API Access的公制URL)时，如下面的gnocchi api所说，它不起作用。

gnocci cli正在寻找像http://servername:8041这样端点。您应该按照文档https://docs.openstack.org/ceilometer/rocky/install/install-base-rdo.html中的说明为gnocci服务创建新的端点，还应该确保redis或其他后端服务已启用并处于活动状态。
