Sstat is a kernel module for Linux 2.6 aimed at providing basic SCSI I/O statistics. While better tools exist for monitoring disk activity, SCSI (or Fibre Channel) tapes have been neglected so far. This module compiles out-of-tree and uses Kprobes to access the information needed so it can be used with "enterprise" kernels as well (where recompilation or rebooting are not acceptable).

Release Notes: Sstat now works on RHEL5 kernels as well as recent vanillas, while maintaining compatibility with older kernels (like in RHEL4).
Release Notes: The code was tested under heavy load (and it survived). It is SMP safe and has a low performance overhead.
