What is the difference between the two groups of NetApp Events below that are shown in the NetApp Template
NetApp File Access Rights Changed
NetApp File Ownership Changed
NetApp Folder Access Rights Changed
NetApp Folder Ownership Changed
NetApp File Access Rights Changed (no from-value)
NetApp File Ownership Changed (no from-value)
NetApp Folder Access Rights Changed (no from-value)
NetApp Folder Ownership Changed (no from-value)
The following are events that can be enabled in the NetApp Auditing template
Synchronous notifications
NetApp File Access Rights Changed
NetApp File Ownership Changed
NetApp Folder Access Rights Changed
NetApp Folder Ownership Changed
Asynchronous notifications
NetApp File Access Rights Changed (no from-value)
NetApp File Ownership Changed (no from-value)
NetApp Folder Access Rights Changed (no from-value)
NetApp Folder Ownership Changed (no from-value)
What synchronous and asynchronous communications are:
FPolicy sends notifications to external FPolicy servers via the FPolicy interface. The notifications are sent either in synchronous or asynchronous mode. The notification mode determines what Data ONTAP does after sending notifications to FPolicy servers.
Asynchronous notifications
With asynchronous notifications, the node does not wait for a response from the FPolicy server, which enhances overall throughput of the system. This type of notification is suitable for applications where the FPolicy server does not require that any action be taken as a result of notification evaluation. For example, asynchronous notifications are used when the Vserver administrator wants to monitor and audit file access activity.
Synchronous notifications
When configured to run in synchronous mode, the FPolicy server must acknowledge every notification before the client operation is allowed to continue. This type of notification is used when an action is required based on the results of notification evaluation. For example, synchronous notifications are used when the Vserver administrator wants to either allow or deny requests based on criteria specified on the external FPolicy server.
What this means is if the Change Auditor NetApp template has enabled any of the Synchronous notifications then all events in that template will become Synchronous notifications and this will delay NetApp sending the events to the template significantly and possibly impact end-user experience.
Support recommends only enabling the (no From-Value) events.
