Start Host-LU QoS Performance Monitoring
Overview
This function starts performance monitoring of Host-LU QoS.
Target ports for monitoring performance
- If this function is started from the [Host-LU QoS] screen, this function starts performance monitoring of the ports that satisfy all the following conditions.
All FC, iSCSI, and SAS ports that are installed in the storage system
Ports which port mode are "CA" or "CA/RA"
Ports without "Undefined" or "Undefined (Error)" state
If this function is started from each [Port QoS] screen of the FC, iSCSI, or SAS, this function starts performance monitoring of the selected port (multiple selections can be made).
When this function is started after port selection, ports with different host interfaces cannot be selected at the same time.
This function can be used, irrespective of whether the QoS mode has been enabled or disabled.
Performance monitoring can be started even if other performance information is being obtained. If performance monitoring is restarted, the performance information that is already obtained is deleted and the collection of performance starts again. The start time is changed to the last time when performance monitoring was restarted.
