![意想不到的是,gnocchi 的行为](https://linux22.com/image/706055/%E6%84%8F%E6%83%B3%E4%B8%8D%E5%88%B0%E7%9A%84%E6%98%AF%EF%BC%8Cgnocchi%20%E7%9A%84%E8%A1%8C%E4%B8%BA.png)
指标由 Ceilometer 等设备的遥测收集,最后发送给 Gnocchi,但 Gnocchi 不允许用户在使用等于 keystone 或 noauth 的身份验证方法时使用诸如gnocchi metric list
或之类的命令。gnocchi resource list
因此,我尝试使用一个更简单的命令来获取状态以解决问题gnocchi status
。
不同的“AUTH_MODE”
在 gnocchi.conf 中使用不同的身份验证方法时,结果gnocchi status
将如下所示:
auth_mode = basic
(gnocchi) status
+--------------------------------------------------+-------+
| Field | Value |
+--------------------------------------------------+-------+
| storage/number of metric having measures to | 13 |
| process | |
| storage/total number of measures to process | 444 |
+--------------------------------------------------+-------+
auth_mode = noauth
(gnocchi) status
Forbidden (HTTP 403)
auth_mode = keystone
(gnocchi) status
The request you have made requires authentication. (HTTP 401)
gnocchi.conf 中的 [keyston-authtoken]
[keystone_authtoken]
auth_type = password
auth_url = http://mng-kh-lab-ctrl-vip-01.ocloud.ir:5000/v3
auth_uri = http://mng-kh-lab-ctrl-vip-01.ocloud.ir:35357
memcached_servers = mng-kh-lab-ctrl-01.ocloud.ir:11211,mng-kh-lab-ctrl-02.ocloud.ir:11211
project_domain_name = default
user_domain_name = default
project_name = service
username = gnocchi
password = 123456
interface = internalURL
region_name = Region_KH_LA

在所有不同的方法中,发送的请求都是使用基本 YWRtaW46以获得其授权。
答案1
在所有不同的方法中,发送的请求都使用基本的 YWRtaW46 进行授权,这真的很奇怪。
这并不奇怪:客户端默认使用基本身份验证。如果您没有为客户端提供正确的身份验证机制。请尝试执行以下操作:
export OS_AUTH_TYPE=password
这样就可以使用 Keystone 作为身份验证。
