Manage Messages


The VSS API runs periodic checks to ensure the VSS Guidelines are in compliance. This is the case for Virtual Machine snapshot life time, Virtual Machine disk consolidation, VMware Tools version status and running status, session invalidation, etc. Also, the API notifies via email upon every request submission/completion or error. However, these checks could produce a considerable amount of emails and in order to address this issue, the API introduced User Messages, which hold simple subject/body objects.

By the end of the week, you can receive a Messages Digest containing all messages which have not been read. This reduces a daily email message per VM to one every seven days. This feature is even more useful when your Request Notification has been set to message or even optimized by following Manage Object Request Notifications to update your notification settings.

If you would like to receive the Messages Weekly Digest, please update your notification settings via either the Cloud Portal, VSS CLI or VSS API.
