License capacity monitoring alarm triggered in VMware vCenter Server 5.x


Article ID: 328004


Updated On:




  • License capacity monitoring alarms are triggered in vCenter Server.
  • After upgrading to vCenter Server 5.x, license capacity monitoring alarms trigger.
  • This issue occurs even when license key counts in the Management tab are under capacity.

    Note: To access the Management tab, click Home > Administration > Licensing. Click the Management tab and select License key option.


This issue occurs because vCenter Server reports that vRAM licensing capacity is exceeded.


This issue is resolved in VMware vCenter Server 5.1 Update 2, available at VMware Downloads. For more information, see the vCenter Server 5.1 Update 2 Release Notes.

VMware has eliminated the vRAM restriction on licenses to VMware vSphere. For more information, see the Updated vRAM Policy. This alarm can be safely ignored or disabled.
To disable the alarm:
  1. Log in to vCenter Server.
  2. Select the vCenter Server at the top level (above Datacenter and Cluster).
  3. Select AlarmDefinition.
  4. Locate the License capacity monitoring alarm.
  5. Right-click the alarm and click Edit Settings.
  6. In General tab, deselect the Enable this alarm option.
