1.概述

Ceilometer是OpenStack中的一个子项目,它像一个漏斗一样,能把OpenStack内部发生的几乎所有的事件都收集起来,然后为计费和监控以及其它服务提供数据支撑。Ceilometer的核心架构图如下:

2.安装

2.1安装服务

apt-get install ceilometer-api
ceilometer-collector ceilometer-agent-central python-ceilometerclient

2.2配置

/etc/ceilometer/ceilometer.conf

[DEFAULT]

#rabbitMQ

rabbit_host = client

rabbit_password = 12345

rabbit_hosts = client:5672

rabbit_userid = guest

[database]

connection = mysql://ceilometer:12345@client/ceilometer

[publisher_rpc]

metering_secret = ADMIN

[keystone_authtoken]

auth_host = client

auth_port = 35357

auth_protocol = http

admin_tenant_name = service

admin_user = ceilometer

admin_password = ceilometers

2.3在keystone中创建ceilometer用户和服务endpoint

keystone user-create –name=ceilometer
–pass=CEILOMETER_PASS –email=ceilometer@example.com

keystone user-role-add –user=ceilometer
–tenant=service –role=admin

keystone service-create –name=ceilometer
–type=metering –description=”Ceilometer Telemetry Service”

keystone endpoint-create
–service-id=the_service_id_above
–publicurl=http://controller:8777/
–internalurl=http://controller:8777/
–adminurl=http://controller:8777/

2.4创建ceilometer的mysql数据表

ceilometer-dbsync

2.5重启服务

service ceilometer-agent-central restart

service ceilometer-api restart

service ceilometer-collector restart

At present, most of the Nova meters will
only work with libvirt front-end hypervisors while test coverage was mostly
done based on KVM. Contributors are welcome to implement other virtualization
backends’ meters or complete the existing ones.
