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

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

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

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

{     "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" }
