从 NSX Manager 集中式 CLI 中，您可以检查每个 ESXi 主机的运行状况。

运行状况将报告为严重、不正常或正常。还可以通过 NSX Manager API 调用 host health-check 命令。

例如： 

nsxmgr> show host host-30 health-status
status: HEALTHY

nsxmgr> show host host-29 health-status
UNHEALTHY, Standard Switch vSwitch1 has no uplinks.

UNHEALTHY, Host host-29 mount point /vmfs/volumes/58e2c6d5-83319ac1-7830-005056014d86
volume "local_esx-06a" free percentage less than 20%: 0%.
Status: UNHEALTHY

nsxmgr> show host host-28 health-status
CRITICAL, VXLAN VDS vds-site-a VNI 200000 multicast addr is not synchronized with VSM: 0.0.0.0.
CRITICAL, VXLAN VDS vds-site-a VNI 200003 multicast addr is not synchronized with VSM: 0.0.0.0.
CRITICAL, VXLAN VDS vds-site-a VNI 5000 multicast addr is not synchronized with VSM: 0.0.0.0.
Status: CRITICAL

CRITICAL, Control plane agent on host is not in established state with controller. Please
investigate host connection issue with esxcli network ip connection
command.
CRITICAL, VXLAN VDS RegionA01-vDS-MGMT VNI 5007 connection to controller is down: 0.0.0.0
(down).

您可以使用 show host hostID health-status detail 命令针对每个参数查看指定主机的详细运行状况。
