The vfsops utility reports vfs operation outliers. A count of the number of operations are grouped
into 10ms, 100ms, 1s, and 10s buckets. The first line of output represents a zone's outliers since
boot, while sequential lines show how many operations have occured during the INTERVAL. By default
vfsops will only output zones that have a non zero value for all buckets.
