Prometheus_VMware_exporter

VMware监控的实现

安装VMware_exporter

组件GitHub地址：https://github.com/pryorda/vmware_exporter

详细的参数说明请查看Github项目仓库中的说明文件

本次使用容器部署，所以只要准备好配置文件添加到容器内启动即可，配置文件如下：

[root@VM-24-14-centos vmware_exporter]# pwd
/usr/local/vmware_exporter
[root@VM-24-14-centos  vmware_exporter]# cat config.env

    vsphere_user: "username"
    vsphere_password: "password"

Prometheus增加VMware监控任务

[root@VM-24-14-centos vmware_exporter]# tail -30 /etc/prometheus/prometheus.yml
  #VMware集群监控
  - job_name: 'vmware_vcenter_1'
    metrics_path: '/metrics'
    static_configs:
      - targets:
        - 'ip'
    params:
      section: [vcenter1]        #选择那个虚拟化集群
    relabel_configs:
      - source_labels: [__address__]
        target_label: Prometheus
      - source_labels: [Prometheus]
        target_label: instance
      - target_label: __address__
        replacement: PrometheusIP:9272
  ##exsi主机监控

Grafana图表配置

图表是从项目中grafana的图表json和grafana官网中图表下载，因公司集群字段与图表过滤字段不一致，需自定义配置。
