vCenter Server 5.0管理启动一台ESXi 5.0（从ESXi 4.1升级）性能数据只能显示实时数据，其他主机正常，处理方法如下：

一、重新启动故障ESXi 5.0管理网络服务

在ESXi主机上重启管理网络服务

1. Connect to the console of your ESXi host.

2. Press F2 to customize the system.

3. Login as root.

4. Using the Up/Down arrows navigate to Restart Management Agents.

 Note: In ESXi 4.1 and ESXi 5.0, this option is available under Troubleshooting Options .

5. Press Enter.

6. Press F11 to restart the services.

7. When the service has been restarted, press Enter.

8. Press Esc to logout of the system.

或

在控制台上执行services.sh restart

在ESX主机上重启管理网络服务

1.Log in to your ESX host as root from either an SSH session or directly from the console.
2.Run this command:


service mgmt-vmware restart

Caution: Ensure Automatic Startup/Shutdown of virtual machines is disabled before running this command or you risk rebooting the virtual machines. For more information, see Restarting hostd (mgmt-vmware) on ESX hosts restarts hosted virtual machines where virtual machine Startup/Shutdown is enabled (1003312) and Determining whether virtual machines are configured to autostart (1000163).
3.Press Enter.
Run this command:

service vmware-vpxa restart

5.Press Enter.
6.Type logout and press Enter to disconnect from the ESX host.
If this process is successful, it appears as:

[root@server]# service mgmt-vmware restart
Stopping VMware ESX Server Management services:
VMware ESX Server Host Agent Watchdog [ OK ]
VMware ESX Server Host Agent [ OK ]
Starting VMware ESX Server Management services:
VMware ESX Server Host Agent (background) [ OK ]
Availability report startup (background) [ OK ]
[root@server]# service vmware-vpxa restart
Stopping vmware-vpxa: [ OK ]
Starting vmware-vpxa: [ OK ]
[root@server]#

二、将ESXi点击断开，然后从清单中移除，然后再次加入vCenter Server

等待一段时间后，天、周的性能数据可以正常显示出来。
