- [com.vmware.vc.sms.ThinProvisionedLunThresholdInitEvent](com.vmware.vc.sms.thinprovisionedlunthresholdinitevent.md)
- [com.vmware.vc.sms.ThinProvisionedLunThresholdClearedEvent](com.vmware.vc.sms.thinprovisionedlunthresholdclearedevent.md)
- [com.vmware.vc.sms.ThinProvisionedLunThresholdCrossedEvent](com.vmware.vc.sms.thinprovisionedlunthresholdcrossedevent.md)
