通过调用Vcenter-Api获取Vcenter中服务器信息

文章目录

通过调用Vcenter-Api获取Vcenter中服务器信息
1. 获取Vmware API帮助文档
2. 获取访问凭证
3. 获取服务器清单
4. 获取服务器更多信息
5. 获取虚机更多信息
6. 获取磁盘信息
7. 获取操作系统相关

1. 获取Vmware API帮助文档

https://developer.vmware.com/apis/vsphere-automation/latest/

2. 获取访问凭证

文档对应url:https://developer.vmware.com/apis/vsphere-automation/latest/cis/api/session/post/
注意这里获取凭证应该是使用post方式
在这里插入图片描述
将调用地址复制出来:https://{api_host}/api/session
将{api_host}替换成我们实际Vcenter地址192.168.0.200
替换后就成了https://192.168.0.200/api/session
方法设置为POST

3. 获取服务器清单

url替换成https://192.168.0.200/api/vcenter/vm
方法改为GET
Headers中key为vmware-api-session-id
value为我们刚才拿到的token

在这里插入图片描述
这样我们就拿到了这个Vc上的服务器清单

4. 获取服务器更多信息

以下内容是通过https://192.168.0.200/api/vcenter/vm查询到的某一个服务器的信息

    {"memory_size_MiB": 8192,"vm": "vm-12311","name": "TEST-WEAPP","power_state": "POWERED_ON","cpu_count": 2},

key	含义
memory_size_MiB	虚拟机总内存
vm	虚拟机ID(这个后续会用到)
name	虚拟机在Vcenter中的名字
power_state	电源状态
cpu_count	虚拟机CPU个数

5. 获取虚机更多信息

方法GET,URL https://192.168.0.200/api/vcenter/vm/vm-12311
在这里插入图片描述
以下是返回的部分内容

{"instant_clone_frozen": false,"cdroms": {"16000": {"start_connected": false,"backing": {"iso_file": "[back01] ISO/Windows Server/2016_64.ISO","type": "ISO_FILE"},"allow_guest_control": true,"label": "CD/DVD drive 1","state": "CONNECTED","type": "SATA","sata": {"bus": 0,"unit": 0}}},"memory": {"hot_add_increment_size_MiB": 4,"size_MiB": 8192,"hot_add_enabled": true,"hot_add_limit_MiB": 131072},略"cpu": {"hot_remove_enabled": false,"count": 2,"hot_add_enabled": true,"cores_per_socket": 1},"scsi_adapters": {"1000": {"pci_slot_number": 160,"scsi": {"bus": 0,"unit": 7},"label": "SCSI controller 0","sharing": "NONE","type": "LSILOGICSAS"}},"power_state": "POWERED_ON","floppies": {},
"disks": {"2000": {"scsi": {"bus": 0,"unit": 0},"backing": {"vmdk_file": "[data01] TEST-WEAPP/TEST-WEAPP-000001.vmdk","type": "VMDK_FILE"},"label": "Hard disk 1","type": "SCSI","capacity": 53687091200},"2001": {"scsi": {"bus": 0,"unit": 1},"backing": {"vmdk_file": "[data01] TEST-WEAPP/TEST-WEAPP_1-000001.vmdk","type": "VMDK_FILE"},"label": "Hard disk 2","type": "SCSI","capacity": 107374182400}},"nvme_adapters": {},"name": "TEST-WEAPP",
网卡信息,略"boot": {"delay": 0,"retry_delay": 10000,"enter_setup_mode": false,"type": "BIOS","retry": false},"serial_ports": {},"boot_devices": [],"guest_OS": "WINDOWS_9_SERVER_64","hardware": {"upgrade_policy": "NEVER","upgrade_status": "NONE","version": "VMX_19"}
}

我们可以在这段json中拿到大部分关于这台服务器的信息,比如:

KEY	含义
cdroms	关于虚拟光驱的内容,可以看到我们这里用了ISO
memory	内存详细信息
cpu	cpu相关信息
nics	网卡的一些信息,这里我隐藏掉了
disks	磁盘的一些信息

6. 获取磁盘信息

这里我们拿到了部分磁盘的信息,磁盘的总大小,还有存储位置
但和我们实际想要的内容是有差距的

"disks": {"2000": {"scsi": {"bus": 0,"unit": 0},"backing": {"vmdk_file": "[data01] TEST-WEAPP/TEST-WEAPP-000001.vmdk","type": "VMDK_FILE"},"label": "Hard disk 1","type": "SCSI","capacity": 53687091200},"2001": {"scsi": {"bus": 0,"unit": 1},"backing": {"vmdk_file": "[data01] TEST-WEAPP/TEST-WEAPP_1-000001.vmdk","type": "VMDK_FILE"},"label": "Hard disk 2","type": "SCSI","capacity": 107374182400}},

我们更像要的内容是,盘符,分区格式,磁盘总大小,剩余空间这些信息.
我们可以用GET方式取https://192.168.0.200/api/vcenter/vm/vm-12311/guest/local-filesystem
在这里插入图片描述

{"C:\\": {"mappings": [{"disk": "2000"}],"free_space": 16884203520,"filesystem": "NTFS","capacity": 53159653376},"D:\\": {"mappings": [{"disk": "2001"}],"free_space": 60841975808,"filesystem": "NTFS","capacity": 107371032576}
}

KEY	含义
free_space	可用空间KB
filesystem	文件系统格式
capacity	分区总大小KB
C:\或D:\	Windows盘符
/home或则/data	linux盘符

现在我们可以很简单的通过遍历json进行简单的加工就能获取到我们想要的具体数据

7. 获取操作系统相关

get访问https://192.168.0.200/api/vcenter/vm/vm-12311/guest/identity

{"full_name": {"args": [],"default_message": "Microsoft Windows Server 2016 (64-bit)","id": "vmsg.guestos.windows444rver64Guest.label"},"name": "WINDOWS_9_SERVER_64","ip_address": "192.168.2.25","family": "WINDOWS","host_name": "TEST-WEAPP"
}
