The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected.

It is calculated using the Instance Volume Performance metric which in turn collects data from the GV$ASM_DISKGROUP_STAT and GV$ASM_VOLUME_STAT views.
To calculate the average write response time for each volume, the total write time is divided by the total number of write responses during the collection interval. The data is displayed for all instances that are part of the cluster.
No user action is required.
