SVI

The server vnode interface component handles this call. The example report that is shown in Figure 1 displays the total number of calls the server received from the specific client and the average server response time in milliseconds, including the XCF transmit and CPU time of the reply. XCF Req is the count of XCF messages that had to be sent to other systems (most likely for token revokes) to process the client request. Qwait counts the number of times a wait was done for an available zFS thread to process the client request.

Note: The output is displayed only when the zFS svi component on this system has received a message from another system.
