ceilometer与gnocchi

ceilometer项目是openstack中用来做计量计费功能的一个组件，后来又逐步发展增加了部分监控采集、告警的功能。由于种种原因，ceilometer项目在Openstack中已经处于一种没落的状态，基本没有什么新的特性开发了，原本该项目的PTL也另起炉灶开始在做Gnocchi项目(ceilometer的后端存储系统)。虽然该项目已经没有前几年活跃，但是还是在很多公有云场景中有比较多的应用，而生产环境中，可能很多公司还用的是M、N版本。

gnocchi解决的问题是大规模地存储和索引时间序列数据和资源。
http://gnocchi.xyz

ceilometer收集虚拟机数据然后将数据存储到gnocchi数据库，最后由grafana 前端展示数据图表。

不过grafana高版本似乎对gnocchi的兼容不足，3-6版本之间的可以实现兼容。grafana6以上的似乎无法兼容 gnocchi 数据源。因此部署时需重新安装6版本以下的grafana实现 gnocchi数据源的添加展示。
且ceilometer有时在主机重启后需要重新启动相关服务才会继续收集数据。

docker restart ceilometer_ipmi ceilometer_compute ceilometer_central ceilometer_notification

部署相关组件

train版本自动安装的grafana 版本7.3.7。无法添加gnocchi的dataresource。。。（一致testing无法成功）
因此想要使用grafana展示gnocchi中数据的话。需要安装更低版本的grafana。
如安装6.3.4版本的grafana，端口号设置为3002避免和通过kolla部署的冲突。

编辑配置文件。

vim /etc/kolla/globals.yml

enable_ceilometer: "yes"
enable_ceilometer_ipmi: "yes"
enable_gnocchi: "yes"
enable_grafana: "yes"

部署安装

kolla-ansible deploy -i /etc/kolla/all-in-one

安装完成查看相关容器运行

安装gnocchiclient 查看数据。

默认部署 ceilometer 数据保存到gnocchi中保存策略是low。基本上5分钟保存一次数据。。。所以数据有时候需要等一下。
长时间无数据且查看相关容器正常运行后或者宿主机重启后建议重启ceilometer_notification容器可能解决问题。

docker restart ceilometer_notification

或者重启 ceilemeter 相关所有容器

docker restart ceilometer_ipmi ceilometer_compute ceilometer_central ceilometer_notification

1.安装gnocchiclient

pip install gnocchiclient

2.加载认证

source /etc/kolla/admin-openrc.sh

3.通过gnocchi-api查看gnocchi中存储数据。
当前采集的资源列表

gnocchi resource list

列出支持资源类别列表

gnocchi resource-type list

列出某个资源的数据采集单元（resource_ID)

gnocchi metric list | grep 511483be-89a2-4b7e-91b8-41adf4276651

显示单个metric的记录数据，（metric_ID）

gnocchi measures show e45156e4-7544-49a1-ab9a-a22fdc1f56e2

数据保存完成且可查看，下一步是通过grafana展示

Grafana展示

安装完成添加gnocchi数据源后使用dashboard模板展示数据。
https://grafana.com/grafana/dashboards/12536

使用kolla部署的grafana版本过高似乎不再支持gnocchi 的数据源插件了。
只好额外安装一个更低版本的grafana软件。6.4.3。。。

yum -y install wget
wget https://dl.grafana.com/oss/release/grafana-6.4.3-1.x86_64.rpm 
sudo yum -y install grafana-6.4.3-1.x86_64.rpm

修改端口为3002，因为kolla部署的grafana容器组件占用了3000

vim /etc/grafana/grafana.ini

[server]
http_port = 3002

修改完成保存。启动grafana6.4.3

systemctl enable grafana-server
systemctl start grafana-server

grafana安装gnocchi 数据源插件

sudo grafana-cli plugins install gnocchixyz-gnocchi-datasource

安装完成重启grafana

systemctl restart grafana-server

设置配置文件，允许grafana6.4.3读取gnocchi数据。

cp /etc/kolla/keystone/keystone.conf /etc/kolla/config/
cp /etc/kolla/gnocchi-api/gnocchi.conf /etc/kolla/config/

配置gnocchi

vim /etc/kolla/config/gnocchi.conf

原来是默认设置了 3000端口，但是默认的grafana 添加gnocchi数据源时一直testing 无法成功。只好使用6.4.3版本grafana的3002 端口。

[cors]
allowed_origin = http://192.168.199.90:3002

配置 keystone

vim /etc/kolla/config/keystone.conf

[cors]
allowed_origin = http://192.168.199.90:3002

设置完成 kolla重新加载配置

kolla-ansible reconfigure -i /etc/kolla/all-in-one

设置gnocchi数据源。使用dashboard模板展示数据。

等待配置重新加载完成后。网页登录进入grafana6.4.3
192.168.199.90:3002

由于这个grafana不是通过kolla 部署的，所以未设置密码。初次登录的话，账户密码都是admin。

添加数据源 Add data source 选择gnocchi

Name Gnocchi
HTTP
	URL http://192.168.199.90:5000
Gnocchi Details
	Auth Mode	keystone
	Domain		default
	Project	User 和Password可以根据根据gnocchi配置文件中的认证填写
	也可以是Project和User选择填写admin, password填写Openstack中admin用户的登录密码

[root@ALLInOne-Kolla ~]# cat /etc/kolla/gnocchi-api/gnocchi.conf 
。。。。。。
[keystone_authtoken]
www_authenticate_uri = http://192.168.199.90:5000/v3
project_domain_id = default
project_name = service
user_domain_id = default
username = gnocchi
password = 928futiqdqBWBzcmjN7lRTr6HesCEz259rtthtIZ
auth_url = http://192.168.199.90:35357
auth_type = password
memcache_security_strategy = ENCRYPT
memcache_secret_key = TA1Zu3xlEbytDYCNyKhyWa1PWaGYOxRzB6oyDH50
memcached_servers = 192.168.199.90:11211

认证没问题即可成功添加 gnocchi的数据源。
数据源添加成功

选择导入相应的 dashboard 模板。

由于个人对 gnocchi的查询语法不熟悉，所以使用了grafana公开的gnocchi dashboard模板来展示

https://grafana.com/grafana/dashboards?dataSource=gnocchixyz-gnocchi-datasource

使用的是模板 12536
选择模板12536
输入模板ID 后按enter 。等待一会后即可导入模板，会让选择数据源，选择刚添加的gnocchi数据源即可。
当然可以自己根据数据源设置dashboard，只是我gnocchi查询不熟。所以直接使用他人的模板了。

效果大致如下
数据展示1
数据展示2

设置保存策略。

5分钟记录一次数据太慢尝试修改保存策略。
通过gnocchi查看已知的保存策略

基本保存策略都是ceilometer，特别的如网络磁盘等数据累加的使用ceilometer-low-rate策略。

修改保存策略

通过docker exec 命令进入ceilometer 相应的容器，查看保存策略的设置。。。

进入ceilometer_notification 查看保存策略

[root@ALLInOne-Kolla ~]# docker exec -it ceilometer_notification bash
(ceilometer-notification)[ceilometer@ALLInOne-Kolla /]$

查看保存策略

cat /etc/ceilometer/gnocchi_resources.yaml

可以看到默认的保存策略为ceilometer-low，特别的metric 有单独的保存策略设置。
可以将该配置文件复制到宿主机的config 配置目录中。修改一定的保存策略设置，然后kolla重新加载配置，即可设置ceilometer新的保存策略。
gnocchi_resources.yaml 配置文件。
https://download.csdn.net/download/dandanfengyun/15501637

mkdir -p /etc/kolla/config/ceilometer
cd /etc/kolla/config/ceilometer

将gnocchi_resources.yaml配置文件复制进去并设置。

vim /etc/kolla/config/ceilometer/gnocchi_resources.yaml

只修改网络相关保存策略为ceilometer-high-rate，其余配置不变。

archive_policy_default: ceilometer-low
archive_policies:

  - resource_type: instance_network_interface
    metrics:

        archive_policy_name: ceilometer-high-rate
    attributes:
      name: resource_metadata.vnic_name
      instance_id: resource_metadata.instance_id

kolla重启加载配置策略

kolla-ansible reconfigure /etc/kolla/all-in-one

配置完成后，已经存在得metric保存策略不变，新建的虚拟实例的相关 metric 保存策略使用新的。
如

尽管修改了保存策略，新创建实例的metric的保存策略也使用的新的策略。但是数据保存还是有问题，还是五分钟保存一次，只是有三个不同的 granularity。。。这好像没什么用。

问题

gnocchi相应的dashboard模板不太好用。且数据保存总是 5min保存一次。

似乎还是使用collectd收集数据到influxdb更合适。
