OpenStack Telemetry 数据收集服务

1 安装配置计算服务

在所有计算节点上:

1.1 安装配置组件

安装包:

# yum install -y openstack-ceilometer-compute

编辑配置文件/etc/ceilometer/ceilometer.conf

[DEFAULT]
...
transport_url = rabbit://openstack:pass123456@controller3  
auth_strategy = keystone

[keystone_authtoken]
...
auth_uri = http://controller3:5000  
auth_url = http://controller3:35357  
memcached_servers = controller3:11211  
auth_type = password  
project_domain_name = default  
user_domain_name = default  
project_name = service  
username = ceilometer  
password = pass123456

[service_credentials]
...
auth_url = http://controller3:5000  
project_domain_id = default  
user_domain_id = default  
auth_type = password  
username = ceilometer  
project_name = service  
password = pass123456  
interface = internalURL  
region_name = RegionOne  

1.2 配置计算节点使用Telemetry

编辑配置文件/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  

1.3 完成安装

开启代理和配置开机启动,并重启计算服务:

# systemctl enable openstack-ceilometer-compute.service
# systemctl start openstack-ceilometer-compute.service

# systemctl restart openstack-nova-compute.service

2 安装配置控制服务

以下操作在控制节点上进行:

2.1 Ceilometer服务:

2.1.1 创建gnocchi数据库

# 用root用户登录数据库
$ mysql -u root -p

# 创建gnocchi数据库
MariaDB [(none)]> CREATE DATABASE gnocchi;

# 赋予用户操作数据库最高权限
MariaDB [(none)]> GRANT ALL PRIVILEGES ON  gnocchi.* TO 'gnocchi'@'controller3' IDENTIFIED BY 'pass123456';  
MariaDB [(none)]> GRANT ALL PRIVILEGES ON  gnocchi.* TO 'gnocchi'@'%' IDENTIFIED BY 'pass123456';

MariaDB [(none)]> exit  

2.1.2 配置Ceilometer服务

2.1.2.1 创建ceilometer用户
$ . admin-openrc

$ openstack user create --domain default --password-prompt ceilometer
User Password:  
Repeat User Password:

$ openstack role add --project service --user ceilometer admin
2.1.2.2 创建ceilometer服务实体
$ openstack service create --name ceilometer \
  --description "Telemetry" metering

2.1.3 配置Gnocchi服务

2.1.3.1 创建gnocchi用户
$ openstack user create --domain default --password-prompt gnocchi
User Password:  
Repeat User Password:

$ openstack role add --project service --user gnocchi admin
2.1.3.2 创建gnocchi服务实体
$ openstack service create --name gnocchi \
  --description "Metric Service" metric
2.1.3.3 创建gnocchi API端点
$ openstack endpoint create --region RegionOne \
  metric public http://controller3:8041

$ openstack endpoint create --region RegionOne \
  metric internal http://controller3:8041

$ openstack endpoint create --region RegionOne \
  metric admin http://controller3:8041

2.1.4 安装组件

2.1.4.1 安装gnocchi组件

首先安装编译所需要的工具和开发包:

$ yum install -y gcc python-devel

安装包:

$ pip install gnocchi[postgresql,keystone]
2.1.4.2 安装ceilometer组件

安装包:

# yum install -y openstack-ceilometer-collector openstack-ceilometer-notification \
  openstack-ceilometer-central python-ceilometerclient

2.1.5 配置组件

2.1.5.1 配置ceilometer服务

编辑配置文件/etc/ceilometer/ceilometer.conf

[DEFAULT]
...
meter_dispatchers=gnocchi  
event_dispatchers=gnocchi

transport_url = rabbit://openstack:pass123456@controller3

[dispatcher_gnocchi]
filter_service_activity = False  
archive_policy = low

[service_credentials]
...
auth_type = password  
auth_url = http://controller3:5000/v3  
project_domain_name = default  
user_domain_name = default  
project_name = service  
username = ceilometer  
password = pass123456  
interface = internalURL  
region_name = RegionOne  
2.1.5.2 配置gnocchi服务

编辑/etc/gnocchi/gnocchi.conf文件

[DEFAULT]
debug = true  
verbose = true  
log_dir = /var/log/gnocchi

[api]
auth_mode = keystone

[keystone_authtoken]
auth_type = password  
auth_url = http://controller3:5000/v3  
project_domain_name = Default  
user_domain_name = Default  
project_name = service  
username = gnocchi  
password = pass123456  
interface = internalURL  
region_name = RegionOne

[database]
backend = sqlalchemy

[storage]
driver = file  
file_basepath = /opt/gnocchi/

[indexer]
url = mysql+pymysql://gnocchi:pass123456@controller3/gnocchi?charset=utf8  

创建一些会使用到的文件夹

$ mkdir /opt/gnocchi
$ mkdir /var/log/gnocchi

初始化gnocchi的indexer和storage

$ gnocchi-upgrade

运行gnocchi:

$ gnocchi-api
$ gnocchi-statsd
$ gnocchi-metricd

创建在gnocchi中Ceilometer资源:

# ceilometer-upgrade --skip-metering-database

2.1.3 完成安装

开启Telemetry服务并且配置随系统启动:

# systemctl enable openstack-ceilometer-notification.service \
  openstack-ceilometer-central.service \
  openstack-ceilometer-collector.service
# systemctl start openstack-ceilometer-notification.service \
  openstack-ceilometer-central.service \
  openstack-ceilometer-collector.service

2.2 块服务

2.2.1 配置Cinder使用Telemetry

编辑配置文件/etc/cinder/cinder.conf

[oslo_messaging_notifications]
...
driver = messagingv2  
$ cinder-volume-usage-audit  --start_time='YYYY-MM-DD HH:MM:SS' \
  --end_time='YYYY-MM-DD HH:MM:SS' --send_actions

2.2.2 完成安装

在控制节点重启块存储服务:

# systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service

在存储节点重启块服务:

# systemctl restart openstack-cinder-volume.service

2.3 镜像服务

2.3.1 配置Glance使用Telemetry

编辑配置文件/etc/glance/glance-api.conf/etc/glance/glance-registry.conf

[DEFAULT]
...
transport_url = rabbit://openstack:pass123456@controller3

[oslo_messaging_notifications]
...
driver = messagingv2  

2.3.2 完成安装

重启镜像服务:

# systemctl restart openstack-glance-api.service openstack-glance-registry.service

2.4 网络服务

2.4.1 配置Neutron使用Telemetry

编辑配置文件/etc/neutron/neutron.conf

[oslo_messaging_notifications]
...
driver = messagingv2  

2.4.2 完成安装

重启网络服务:

# systemctl restart neutron-server.service

3 验证操作
