This metric indicates the performance of the volumes present in an Automatic Storage Management (ASM) instance. This metric shows the volume performance parameters for all the volumes created on all disk groups mounted on an ASM Instance. This metric is used to collect information, for example, total I/O and read/write requests, total I/O and read/write time, and the total number of bytes read/written to the volume. It also shows the response of the volume for read, write, and I/O throughput and the Read Write Errors.
