注意事項

在安裝過程發現 Queens 版官方的套件有問題，導致在安裝 gnocchi-api 時會有python2 和 python3 套件衝突，導致刪除 cinder-api、 keystone、libapache2-mod-wsgi、 nova-placement-api、 openstack-dashboard，因此需要加入新的 repository

Ubuntu 16.04版本要安裝 gnocchi-api 需要加入

add-apt-repository cloud-archive:queens-proposed

官方 BUG: :

建立資料庫

請注意你的使用者和密碼

# mysql -u root -p
MariaDB [(none)]> CREATE DATABASE gnocchi;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'localhost' \
  IDENTIFIED BY 'GNOCCHI_DBPASS';
  
MariaDB [(none)]> GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'%' \
  IDENTIFIED BY 'GNOCCHI_DBPASS';

建立服務

建立 OpenStack gnocchi 和 ceilometer 使用者及服務

請將 $ALL_HOST 改為 controller IP

# openstack user create --domain default --password-prompt ceilometer
# openstack user create --domain default --password-prompt gnocchi

# openstack role add --project service --user ceilometer admin
# openstack role add --project service --user gnocchi admin

# openstack service create --name gnocchi --description "Metric Service" metric

# openstack endpoint create --region RegionOne metric public http://$ALL_HOST:8041
# openstack endpoint create --region RegionOne metric internal http://$ALL_HOST:8041
# openstack endpoint create --region RegionOne metric admin http://$ALL_HOST:8041

修改 gnocchi.conf

修改 /etc/gnocchi/gnocchi.conf

根據你的環境，修改下面參數

[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.1.10

[api]
auth_mode = keystone
middlewares = oslo_middleware.cors.CORS
middlewares = keystonemiddleware.auth_token.AuthProtocol
auth_mode = keystone

[indexer]
url = mysql+pymysql://openstack:openstack@192.168.1.10/gnocchi

[keystone_authtoken]
auth_host = http://192.168.1.10:5000/v3/
auth_protocol = http
admin_user = admin
admin_password = openstack
admin_tenant_name = admin
auth_url = http://192.168.1.10:5000/v3
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = gnocchi
password = openstack
interface = internalURL
region_name = RegionOne

[storage]
coordination_url = file:///var/lib/gnocchi/locks
file_basepath = /var/lib/gnocchi
driver = file

新增 gnocchi-api.conf

新增 /etc/apache2/sites-available/gnocchi-api.conf

Listen 8041

</VirtualHost>

建立 gnocchi 資料表

使用 gnocchi-upgrade 建立資料表

# gnocchi-upgrade

重啟 gnocchi 服務

# service apache2 restart
# service gnocchi-metricd restart

修改 /var/lib/gnocchi 權限

請將 /var/lib/gnocchi 權限設為 gnocchi

# chown -R gnocchi:gnocchi /var/lib/gnocchi

修改 admin-openrc

如果要使用 gnocchi 的指令，需要將 admin-openrc 加入以下參數，才能使用指令

export OS_AUTH_TYPE=password

安裝 ceilometer

Controller 節點

# apt install -y ceilometer-agent-notification ceilometer-agent-central

修改 ceilometer.conf

跟據環境，修改以下參數

修改 /etc/ceilometer/ceilometer.conf

[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.1.10

[dispatcher_gnocchi]
filter_service_activity = False
archive_policy = high

[service_credentials]
auth_url = http://10.50.2.10:5000/v3
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = ceilometer
password = openstack
interface = internalURL
region_name = RegionOne

建立 ceilometer resource

在 gnocchi 裡建立 ceilometer 的 resource

# ceilometer-upgrade

重啟 ceilometer 服務

# service ceilometer-agent-central restart
# service ceilometer-agent-notification restart

修改 glance-api.conf 和 glance-registry.conf

修改 /etc/glance/glance-api.conf 和 /etc/glance/glance-registry.conf

[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.1.10

[oslo_messaging_notifications]
driver = messagingv2

修改 neutron.conf

修改 /etc/neutron/neutron.conf

[oslo_messaging_notifications]
driver = messagingv2

修改 cinder.conf

修改 /etc/cinder/cinder.conf (volume節點上的也需要修改)

[oslo_messaging_notifications]
driver = messagingv2

修改 heat.conf

修改 /etc/heat/heat.conf

[oslo_messaging_notifications]
driver = messagingv2

重啟上述服務

# service glance-registry restart
# service glance-api restart

# service neutron-server restart

# service apache2 restart
# service cinder-api restart
# service cinder-scheduler restart
# service cinder-volume restart

# service heat-api restart
# service heat-api-cfn restart
# service heat-engine restart

Compute 節點

安裝 ceilometer-agent-compute

# apt-get install ceilometer-agent-compute

修改 ceilometer.conf

根據環境，修改以下參數

修改 /etc/ceilometer/ceilometer.conf

[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.1.10
[service_credentials]
auth_url = http://10.50.2.10:5000/v3
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = ceilometer
password = openstack
interface = internalURL
region_name = RegionOne

修改 nova.conf

修改 /etc/nova/nova.conf

[DEFAULT]
instance_usage_audit = True
instance_usage_audit_period = hour
notify_on_state_change = vm_and_task_state

[oslo_messaging_notifications]
driver = messagingv2

重啟服務

# service ceilometer-agent-compute restart
# service nova-compute restart

修改 polling.yaml

為了監測 VM 的 disk，增加下列至 /etc/ceilometer/polling.yaml 的 some_pollsters

        - disk.usage
        - disk.device.usage
        - disk.device.read.bytes
        - disk.device.read.requests
        - disk.device.write.bytes
        - disk.device.write.requests

其他事項

監測的間隔預設為5分鐘，政策為 low，可以使用 gnocchi 查看其他監測的政策，預設有三種: low, medium , high ，granularity 為間隔時間，也可以建立自己的政策，目前尚未嘗試。

# gnocchi archive-policy list

|        |             | - points: 8760, granularity: 1:00:00, timespan: 365 days, 0:00:00     |                                 |
| low    |           0 | - points: 8640, granularity: 0:05:00, timespan: 30 days, 0:00:00      | std, count, min, max, sum, mean |
| medium |           0 | - points: 10080, granularity: 0:01:00, timespan: 7 days, 0:00:00      | std, count, min, max, sum, mean |
|        |             | - points: 8760, granularity: 1:00:00, timespan: 365 days, 0:00:00     |                                 |
+--------+-------------+-----------------------------------------------------------------------+---------------------------------+

若要修改間隔，請修改 ceilometer.conf 的 [dispatcher_gnocchi]，以及/etc/ceilometer/polling.yaml

ceilometer.conf
[dispatcher_gnocchi]
archive_policy = high

polling.yaml (interval原為300，compute上的也要修改)

polling.yaml
sources:
    - name: some_pollsters
      interval: 60

conteroller 重啟服務

# service ceilometer-agent-central restart
# service ceilometer-agent-notification restart

compute 重啟服務

# service ceilometer-agent-compute restart

透過 gnocchi 的指令，可以取得 VM 的監控值，用 resource show --type instance VM_UUID， 可以得到此 VM 的各資源監測的 ID

# gnocchi resource show --type instance 7e157c6a-7b2a-4893-8819-bfc033e37f39

再透過 gnocchi measures show METRICS_ID，查詢上面的 metrics 的監測值，例如要查詢上述 VM 的 cpu_util (CPU 使用率)

若要取得 VM 網路的監測值，使用 gnocchi resource list --type instance_network_interface， 取得 ID

# gnocchi resource list --type instance_network_interface | grep 7e157c6a-7b2a-4893-8819-bfc033e37f39

再使用 gnocchi resource show 取得監測資源 ID

接下來用gnocchi measures show METRICS_ID，根據上述的 ID 取得監測值

更快的查詢方式，根據VM ID查詢，查詢 instance 相關監測值: (resource-type 為 instance，最後面的參數為要查詢的 metrics，範例為 cpu_util)

# gnocchi measures aggregation --resource-type instance --query 'instance_id="7e157c6a-7b2a-4893-8819-bfc033e37f39"' --granularity 60 --aggregation mean -m cpu_util

查詢 instance network interface 相關監測值:(resource-type為 instance_network_interface，最後面的參數為要查詢的metrics， 範例為network.incoming.bytes

# gnocchi measures aggregation --resource-type instance_network_interface  --query 'instance_id="7e157c6a-7b2a-4893-8819-bfc033e37f39"' --granularity 60 --aggregation mean -m network.incoming.bytes
