湯糰出人意料

度量標準由 Ceilometer 等通過 Telemetry 收集，並最終發送到 Gnocchi，但 Gnocchi 不允許使用者使用命令，例如gnocchi metric list或gnocchi resource list同時使用等於 keystone 或 noauth 的 auth 方法。

所以我嘗試通過使用更簡單的命令來解決問題，只是為了獲取狀態 - gnocchi status。

不同的“AUTH_MODE”

在 gnocchi.conf 中使用不同的身份驗證方法時，結果gnocchi status如下所示：

auth_mode = 基本

(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 = 基石

(gnocchi) status

The request you have made requires authentication. (HTTP 401)

$$ keyston-authtoken $$在 gnocchi.conf 中

[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

不同 auth_modes 上的 TCPDUMP

基本的 ：

奇怪的是，在所有不同的方法中，發送的請求都使用基本的 YWRtaW46進行授權。

這並不奇怪：客戶端的預設設置是使用基本身份驗證。如果您沒有為客戶端提供正確的身份驗證機制。嘗試這樣做：

export OS_AUTH_TYPE=password

這樣 Keystone 就被用作身份驗證。
