Knowledge Base article:

Summary

The host state monitor indicates whether a virtualization host that is managed by Virtual Machine Manager (VMM) is in a state which requires administrator attention. If the state is unknown, monitoring has not yet begun for the virtualization host.

Causes

A host which is labeled as needs attention by Virtual Machine Manager will cause this monitor to go into a critical state.

Resolutions

In the Virtual Machine Manager console, locate the host in the fabric attention and access the status tab of its properties to effectively troubleshoot the issue requiring attention.
