ESX or vCenter warning icon under Host status

Table of contents

Updated September 23, 2016

Overview

ESX or vCenter server shows the following warning in yellow under Host status:

Polling status is ok.

Environment

All VIM versions

Detail

The Host status is based on the overallStatus property with which the value is in the API documentation:

"General health of this managed entity. The value combines the status of all the alarms attached to a managed entity. If any of the alarms has a gray status, the overall status of the managed entity is gray. Otherwise, if any of the alarms has a red status, the overall status of the managed entity is red. Otherwise, if any of the alarms has a yellow status, the overall status of the managed entity is yellow. Otherwise, the overall status of the managed entity is green."

Then in the VIM, the host status is mapped as follows:

  • Yellow - API Warning
  • Gray - API Unknown
  • Red - API Down
  • Green - API Up
  • Other - API Unknown


Virtual Machine is computed the same way as the ESX Host status.

We looked at some hosts and they are in "yellow" which means we already get that "warning" status from VMware. Connecting to vCenter or host by vSphere client should help find out what is going on
