1 准备虚拟环境

yum install -y python-setuptools python-devel

easy_install virtualenv virtualenvwrapper pip

pip install Flask -i http://pypi.douban.com/simple

mkdir ~/workspaces

echo "export WORKON_HOME=~/workspaces" >> .bashrc

source /usr/bin/virtualenvwrapper.sh

2 分别安装Ceilometer(kilo)和Goncchi(master)

源码安装ceilometer：

(env)#git clone https://github.com/openstack/ceilometer.git

(env)#cd ceilometer

(env)#git checkout -b kilo remotes/origin/stable/kilo

(env)#python setup.py install

(env)#tox -e genconfig

(env)#mkdir /etc/ceilometer

(env)#cp etc/ceilometer/* /etc/ceilometer/

(env)# ls /etc/ceilometer/

api_paste.ini  event_definitions.yaml  pipeline.yaml      policy.json  ceilometer.conf  event_pipeline.yaml

同样方法安装python-ceilometerclient

(env)#git clone https://github.com/openstack/python-ceilometerclient

(env)#cd python-ceilometerclient/

(env)#git checkout -b kilo remotes/origin/stable/kilo

(env)#python setup.py install

源码安装gnocchi：

请参考：http://blog.sina.com.cn/s/blog_6de3aa8a0102vgop.html

(env)#python setup.py install

(env)#tox -e genconfig

3 整合配置

gnocchi的配置基本按照http://blog.sina.com.cn/s/blog_6de3aa8a0102vgop.html即可。

ceilometer的配置如下：vim /etc/ceilometer/ceilometer.conf

[DEFAULT]

rabbit_host=192.168.10.120

rabbit_port=5672

rabbit_hosts=192.168.10.120:5672

policy_file=policy.json

[alarm]

record_history=True

evaluation_service=ceilometer.alarm.service.SingletonAlarmService

[api]

port=8777

host=0.0.0.0

[coordination]

backend_url=redis://192.168.10.120:6379

[database]

metering_connection = mysql://root:password@127.0.0.1/ceilometer?charset=utf8

event_connection = mysql://root:password@127.0.0.1/ceilometer?charset=utf8

alarm_connection = mysql://root:password@127.0.0.1/ceilometer?charset=utf8

[event]

os_tenant_name=services

os_auth_url=http://192.168.10.120:35357/v2.0

os_region_name=RegionOne

[alarms]

gnocchi_url = http://192.168.10.120:8041

[dispatcher_gnocchi]

filter_project = admin

filter_service_activity = False

archive_policy = low

url = http://192.168.10.120:8041

archive_policy_file = /etc/ceilometer/gnocchi_archive_policy_map.yaml

在/etc/ceilometer/目录下创建gnocchi_archive_policy_map.yaml文件

# cat /etc/ceilometer/gnocchi_archive_policy_map.yaml

# This file is used to map a metric name to corresponding archive policy

# and used by the ceilometer dispatcher.

# Format: :

cpu_utils: "high"

disk.*: "low"

volume.*: "high"

4 配置其它组件服务实现ceilometer的监控功能

Compute

Image

Block Storage

Networking

Object Stroage

以上配置请参考官方文档。

http://docs.openstack.org/juno/install-guide/install/yum/content/ch_ceilometer.html

5 启动ceilometer和gnocchi的相关进程

首先创建archive_policy，可以参考以下脚本

# cat post_archive_policy.sh

RAW_TOKEN=`curl -s -X POST http://127.0.0.1:5000/v2.0/tokens -H "Content-Type: application/json"  -d '{"auth": {"tenantName": "'"$OS_TENANT_NAME"'", "passwordCredentials":{"username": "'"$OS_USERNAME"'", "password": "'"$OS_PASSWORD"'"}}}'`

#echo $RAW_TOKEN

TOKEN=`echo $RAW_TOKEN | python -c "import sys; import json; tok = json.loads(sys.stdin.read()); print tok['access']['token']['id'];"`

#echo $TOKEN

curl -H "Content-Type: application/json" \

     -H "X-Auth-Token: $TOKEN" \

     -X POST \

     -d '{  "name": "low",

            "back_window": 0,

            "definition": [

                {

                    "granularity": "1s",

                    "timespan": "1 hour"

                },

                {

                    "points": 48,

                    "timespan": "1 day"

                }

              ]

            }' \

       http://192.168.10.120:8041/v1/archive_policy  \

| python -m json.tool

若创建成功，则可以在数据库表中查询到。

启动各个服务

(env)#gnocchi-api

(env)#ceilometer-polling

(env)#ceilometer-collector

(env)#ceilometer-agent-central

(env)#ceilometer-agent-notification

(env)#ceilometer-agent-compute

(env)#ceilometer-api

(env)#ceilometer-agent-ipmi

(env)#ceilometer-alarm-evaluator

(env)#ceilometer-alarm-notifier

6 修订一些问题和bug

（1）      ceilometer-agent-compute报错如下：

解决办法：

说明ceilometer+gnocchi的虚拟环境中确实libvirt库，执行安装即可

(env) # easy_install pyton-libvirt 

另外需要注意的是上面配置文件中涉及到的目录或文件，当系统没有时需要手动创建，以免带来不必要的麻烦。

（2）如果你发现各个表中都没有数据，resource表，metric表等全是空的（不像下图那样）。

解决方法：

请参考https://review.openstack.org/#/c/180409/ 中我提的patch.

修改env/lib/python2.7/site-packages/gnocchi/ceilometer/dispatcher.py +158

将 for metric, policy in enumerate(self.gnocchi_archive_policy_data):

换为 for metric, policy in self.gnocchi_archive_policy_data.items():

因为在处理gnocchi_archive_policy_map.yaml文件时进行正则表达宽匹配时，函数fnmatch.fnmatch(metric_name, metric)传入的参数metric是整数据(0,1,2….)，固没有len()方法，根源是使用了enumerate()函数，获得metric的值不是预期的。

（3）当你创建虚拟机用的flavor其ID是自动生成类似于'9212d3f4-58e3-4a3a-8f2a-eec60f2e717a'时：

ceilometer-collector进程报错，如下：

oslo_messaging.notify.dispatcher ValueError: invalid literal for int() with base 10: '9212d3f4-58e3-4a3a-8f2a-eec60f2e717a'

解决方法：

请参考https://review.openstack.org/#/c/180380/ 中我提的patch.

修改env/lib/python2.7/site-packages/gnocchi/ceilometer/resources/instance.py文件第33和37行，将int(metadata['instance_flavor_id'])换为metadata['instance_flavor_id']

       将int(metadata["flavor"]["id"])换为metadata["flavor"]["id"]

并且，修改env/lib/python2.7/site-packages/gnocchi/rest/__init__.py +765

       将"flavor_id": int 换为 "flavor_id": six.text_type

最后，将gnocchi数据库instance表中的flavor_id字段的类型改为VARCHAR 255，或者将gnocchi数据库中的表全部删去，重新执行gnocchi-dbsync。

（4）当你创建的volume或者image没有名称时(openstack命令行下是允许的)，默认是None，其它字段也类似，这样的资源gnocchi无法记录监控数据，因为在创建resource和meitric时报错创建失败。

原因是在env/lib/python2.7/site-packages/gnocchi/ceilometer/resources目录下image.py  ，instance.py，network.py，volume.py这些文件中都有extra_attributes，在获得其值的时候没有将None转换为Unicode类型，其代码默认这些字段都是完整的，正常的string，非None的。所以如有必要可以加str()强制转换为Unicode来避免错误。
