如何使用api获取Vcenter总体统计信息

from pyVim.connect import SmartConnect, Disconnect
from pyVmomi import vim
import ssl

# 替换为您的vCenter信息
vcenter_host = "your_vcenter_host"
vcenter_user = "your_vcenter_user"
vcenter_password = "your_vcenter_password"

# 忽略SSL证书验证
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_NONE

# 连接到vCenter
si = SmartConnect(host=vcenter_host, user=vcenter_user, pwd=vcenter_password, sslContext=context)

# 获取vCenter的根文件夹
content = si.RetrieveContent()
root_folder = content.rootFolder

# 获取总体统计信息
stats_manager = content.statsManager
summary = stats_manager.QueryPerfSummaryData()

# 打印总体统计信息
print("Total Memory Usage: {} MB".format(summary.memory.usage / (1024 * 1024)))
print("Total CPU Usage: {} MHz".format(summary.cpu.usage / 1000))

# 断开与vCenter的连接
Disconnect(si)
