RemoveWeeklySnapshot

Vmware 虚拟机自动化程序：自动化导出虚拟机和快照信息，自动化删除旧快照。

Todo List

  • Yaml 文件保存配置信息
  • 通过 Yaml 文件信息连接vCenter/Esxi
  • 文件获取所有 vms
  • 获取所有 snapshots
  • 筛选出15天（半个月）前的 snapshots
  • 以上内容以 Excel 表格的形式导出，超出 15 天的快照蓝色底填充标识
  • 最后删除 15 天前的 snapshot，并同时记录删除的 snapshot 日志信息
  • 设置计划任务，每周六（或 每15 天）执行一次
  • 增加排除不能删除的 snapshots 信息，用红色底填充标识
  • 删除快照前/后发送邮件通知
  • 多线程删除（控制每台 vCenter 不可以同时删除超过 4 个快照）
  • 改用数据库保存管理节点账号密码（加密）

输出所有可用的属性和方法

你想获取 代码 示例输出
名称 vm.name "WebServer-01"
MOID vm._moId "vm-12"
电源状态 vm.runtime.powerState poweredOn / poweredOff
开机时间 vm.runtime.bootTime datetime 对象
CPU数 vm.config.hardware.numCPU 4
内存(MB) vm.config.hardware.memoryMB 8192
操作系统 vm.config.guestFullName "CentOS 7 (64-bit)"
IP地址 vm.guest.ipAddress "192.168.1.100"

  8. RevertToCurrentSnapshot / RevertToCurrentSnapshot_Task：将虚拟机恢复到当前快照的状态。
  9. Migrate / MigrateVM_Task：迁移虚拟机到不同的主机或数据存储。
  10. SetCustomValue：设置自定义属性值，以便在虚拟机上存储额外信息。

属性列表

这些属性通常包含关于虚拟机或其他资源的状态和配置信息。以下是一些关键属性的说明：

  1. name：虚拟机的名称。
  2. guest：关于虚拟机操作系统的信息，如操作系统类型、版本等。
  3. config：虚拟机的配置详情，例如 CPU、内存、硬盘等。
  4. runtime：虚拟机的运行时状态，包括电源状态（开机、关机、挂起等）。
  5. snapshot：当前虚拟机的快照信息。
  6. summary：虚拟机的概述信息，包括状态、资源使用情况等。
  7. resourcePool：虚拟机所在的资源池。
  8. datastore：虚拟机的存储位置，指向其使用的存储库。
  9. overallStatus：虚拟机的总体状态，可能是正常、警告、错误等。
  10. recentTask：最近执行的任务列表。

其他属性

  • capability：虚拟机支持的功能，如支持的虚拟硬件版本。
  • declaredAlarmState：声明的警报状态，用于监控虚拟机的健康状况。
  • triggeredAlarmState：触发的警报状态，显示当前激活的警报。
