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

            },
            "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,

            "scsi": {
                "bus": 0,
                "unit": 7
            },
            "label": "SCSI controller 0",
            "sharing": "NONE",
            "type": "LSILOGICSAS"
        }
    },
    "power_state": "POWERED_ON",
    "floppies": {},
"disks": {
        "2000": {
            "scsi": {
                "bus": 0,

                "vmdk_file": "[data01] TEST-WEAPP/TEST-WEAPP-000001.vmdk",
                "type": "VMDK_FILE"
            },
            "label": "Hard disk 1",

        },
        "2001": {
            "scsi": {
                "bus": 0,

            },
            "backing": {
                "vmdk_file": "[data01] TEST-WEAPP/TEST-WEAPP_1-000001.vmdk",

            },
            "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"
}
