vfsops

Dump out vfs op buckets for all running zones.

The first output shows historic "since boot" data, while the following output shows you the difference since the last interval (currently hardcoded at 5s).

Usage

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.
