Monitoring File System Latency with fsstat

in Oracle Solaris Performance, Panics, Hangs, and Dtrace (MOSC)

Solaris 11.4 (beta) comes with a new version of the fsstat command. Why is this interesting? Because with the newly added -l option now fsstat is able to report latency information on read, write, and readdir operations for file system types or individual file systems.

The latency information is independent of physical I/O operations.

Therefore it is representative of file system performance, as seen by applications which helps improving troubleshooting performance issues in that area.

Howdy, Stranger!
