grafana+telegraf+influxdb监控vcenter6.7环境

目的

通过grafana平台展示vcenter6.7里面的数据

环境描述

1台vcenter appliance+3台esxi6.7+若干台虚拟机组成的vsan环境
grafana+telegraf+influxdb所在环境为一台centos7.4虚拟机
- grafana版本7.3.4
- telegraf版本1.16.3
- influxdb版本1.8.3

安装并配置过程

1.安装grafana

添加yum库

# vim /etc/yum.repos.d/grafana.repo

[grafana]
name=grafana
baseurl=https://packages.grafana.com/oss/rpm
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packages.grafana.com/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt

启动grafana-server服务

sudo systemctl daemon-reload
sudo systemctl start grafana-server
sudo systemctl status grafana-server

设置开机自启动
```
systemctl enable grafana-server
```
开机浏览器访问http://ip:3000
默认用户名和密码都是admin
首次登陆会要求更换密码官网文档https://grafana.com/docs/grafana/latest/installation/rpm/

2.安装并配置influxdb

创建influxdb yum配置文件

# cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo
[influxdb]
name = InfluxDB Repository - RHEL \$releasever
baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key
EOF

更新yum缓存
```
# sudo yum makecache fast
```

安装influxdb

# sudo yum -y install influxdb vim curl

开启influxdb服务并设置成开机自启动

# sudo systemctl start influxdb && sudo systemctl enable influxdb

参考文档

3.安装并配置telegraf

安装telegraf并配置和influxdb连接方式
```
# sudo yum -y install telegraf
```

配置vsphere output插件

# sudo vim /etc/telegraf/telegraf.conf
# Configuration for sending metrics to InfluxDB
[[outputs.influxdb]]
  urls = ["http://127.0.0.1:8086"]
  database = "vmware"
  timeout = "0s"

配置vsphere input插件,将其中的vcenter信息换成你的

  [[inputs.vsphere]]
  #### List of vCenter URLs to be monitored. These three lines must be uncommented
  ### and edited for the plugin to work..
  interval = "20s"
  vcenters = [ "https://10.10.90.165/sdk" ]
  username = "administrator@vsphere.local"
  password = "******"

  vm_metric_include = []
  host_metric_include = []
  cluster_metric_exclude = ["*"]
  datastore_metric_exclude = ["*"]

  max_query_metrics = 256
  timeout = "60s"
  insecure_skip_verify = true

  ## Historical instance
  [[inputs.vsphere]]
  interval = "300s"
  vcenters = [ "https://10.10.90.165/sdk" ]
  username = "administrator@vsphere.local"
  password = "******"

  datastore_metric_include = [ "disk.capacity.latest", "disk.used.latest", "disk.provisioned.latest"]
  insecure_skip_verify = true
  force_discover_on_init = true
  cluster_metric_include = ["*"]
  datacenter_metric_include = ["*"]
  host_metric_exclude = ["*"] # Exclude realtime metrics
  vm_metric_exclude = ["*"] # Exclude realtime metrics

  max_query_metrics = 256
  collect_concurrency = 3

重新启动服务，加载刚修改的配置

sudo systemctl restart telegraf
sudo systemctl enable telegraf

验证是否有InfluxDB Metrics

[root@localhost ~]# influx
Connected to http://localhost:8086 version 1.8.3
InfluxDB shell version: 1.8.3

如查看到有以上metrics输出，说明telegraf能够正确获取vcenter数据并存入到influxdb中
参考文档

4.添加influxdb数据源
添加数据源

选择influxdb数据源

添加influxdb信息

5.添加granafa上关于vcenter6.7的dashboard

通过granafa官网dashboard库，下载对应的dashboard,并上传,dashboard地址下载dashboard 其他dashboard下载位置通过granafa上传dashboard的json文件
添加influxdb数据源

6.默认dashboard存在的问题及解决办法

安装后datastore dashboard报错

解决办法:

# wget https://grafana.com/api/plugins/grafana-piechart-panel/versions/1.6.1/download
# unzip unzip grafana-piechart-panel-1.6.1.zip
# mv grafana-piechart-panel/ /var/lib/grafana/plugins/grafana-piechart-panel/
