我是靠谱客的博主还单身麦片，最近开发中收集的这篇文章主要介绍Ceilometer + Gnocchi + Aodh，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

本处主要讲述Gnocchi 的安装及配置，其它Module的安装可以参考 http://docs.openstack.org/mitaka/install-guide-rdo/

部署环境

系统版本： CentOS7

Openstack版本： Mitaka

1.创建Gnocchi的数据库

1 CREATE DATABASE gnocchi;
2 GRANT ALL PRIVILEGES ON gnocchi.* TO '$USERNAME'@'localhost' IDENTIFIED BY '$PASSOWRD';
3 GRANT ALL PRIVILEGES ON gnocchi.* TO '$USERNAME'@'%' IDENTIFIED BY '$PASSOWRD';

2.控制节点安装Gnocchi

1 sudo yum install openstack-gnocchi-api openstack-gnocchi-metricd openstack-gnocchi-statsd

3.创建Username及Service

1 openstack user create --domain default --password-prompt gnocchi
2 openstack role add --project service --user gnocchi admin
3  
4 openstack service create --name gnocchi --description "OpenStack Metric"  metric
5 openstack endpoint create --region RegionOne metric public http://$CONTROLLER_IP:8041
6 openstack endpoint create --region RegionOne metric admin http://$CONTROLLER_IP:8041
7 openstack endpoint create --region RegionOne metric internal http://$CONTROLLER_IP:8041

4. 配置Gnocchi

 1 vim /etc/gnocchi/gnocchi.conf
 2  
 3 [database]
 4 backend = sqlalchemy    #配置存储index的数据库类型
 5  
 6  
 7 [indexer]
 8 url = mysql+pymysql://$USERNAME:$PASSWORD@$CONTROLLER_ip/gnocchi
 9  
10  
11 [keystone_authtoken]    #配置gnocchi服务的权限信息
12 auth_uri = http://$CONTROLLER_IP:5000/v3
13 identity_uri = http://$CONTROLLER_IP:35357/
14 admin_user = $USERNAME
15 admin_password = $PASSWORD
16 admin_tenant_name = service
17 signing_dir = /var/cache/gnocchi
18  
19  
20 [statsd]               #配置gnocchi服务的标识信息（忽略Gnocchi的采样数据），Gnocchi服务相关的信息
21 resource_id = 
22 user_id =
23 project_id =
24 archive_policy_name = low
25  
26  
27 [storage]              #配置storage的后端driver，默认是file
28 coordination_url = file:///var/lib/gnocchi/locks
29 driver = file
30 file_basepath = /var/lib/gnocchi
31  
32 ---------------------------------------------------------------------------------------------------
33 vim /etc/gnocchi/api-paste.ini
34  
35 [pipeline:main]        #鉴权请求，否则无法执行policy.conf指定admin的操作
36 pipeline = gnocchi+auth
37 
38 #创建gnocchi服务需要的目录
39 mkdir /var/cache/gnocchi  && chown gnocchi:gnocchi -R  /var/cache/gnocchi
40 mkdir /var/lib/gnocchi  && chown gnocchi:gnocchi -R  /var/lib/gnocchi

5.初始化Gnocchi 服务的数据库

1 gnocchi-upgrade

6.启动Gnocchi服务

1 systemctl enable openstack-gnocchi-api.service openstack-gnocchi-metricd.service openstack-gnocchi-statsd.service
2   
3 systemctl start openstack-gnocchi-api.service openstack-gnocchi-metricd.service openstack-gnocchi-statsd.service
4 #Mitaka版本初始化数据库时，并创建默认的archive-policy  https://review.openstack.org/#/c/290626/
5 gnocchi archive-policy create -d granularity:5m,points:12 -d granularity:1h,points:24 -d granularity:1d,points:30 low
6 gnocchi archive-policy create -d granularity:60s,points:60 -d granularity:1h,points:168 -d granularity:1d,points:365 medium
7 gnocchi archive-policy create -d granularity:1s,points:86400 -d granularity:1m,points:43200 -d granularity:1h,points:8760 high
8 gnocchi archive-policy-rule create -a low -m "*" default

7.修改Ceilometer配置文件

 1 vim  /etc/ceilometer/ceilometer.conf
 2  
 3 [DEFAULT]
 4 meter_dispatchers = gnocchi
 5  
 6 [api]
 7 gnocchi_is_enabled = true
 8  
 9 [dispatcher_gnocchi]              
10 filter_project = service              
11 filter_service_activity = True
12 url = http://$CONTROLLER_IP:8041

8.重启Ceilometer服务

1 systemctl restart openstack-ceilometer-api.service openstack-ceilometer-collector.service openstack-ceilometer-notification.service

9.示例

创建Ceilometer告警

1 gnocchi metric list
2 gnocchi resource list
3  
4  
5 ceilometer alarm-gnocchi-resources-threshold-create --name gnocchi_test_network   --description 'storage.objects.containers' --alarm-action 'log://' --evaluation-periods 2 
6 --aggregation-method max --comparison-operator gt --threshold 5871354.0 -m network.incoming.bytes --resource-type instance_network_interface 
7 --resource-id addbb3ba-5b1e-543f-ba8a-1010e5d36dbc --repeat-actions true
