X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 11 Oct 2005 18:03:53 -0000 I've just finished the first version of ufsstat, a tool to show local filesystem statistics much like nfsstat does for NFS. The patch and tool is against 6.0, but it will probably apply and work fine under -CURRENT and possibly 5.x as well. I'm looking for bug reports, comments/suggestions on style(9), and anything else, since this is my first C project, and of course first real FreeBSD contribution. :) To use it, do this: cd /tmp fetch http://www.googlebit.com/software/ufsstat/ufsstat-20051011.tar.gz cd /usr tar xvzf /tmp/ufsstat-20051011.tar.gz patch <./ufsstats.patch add: OPTIONS UFSSTAT to your kernel. Rebuild and install world/kernel. Now, you can use ufsstat to show you statistics from your local filesystems, like this: # ufsstat Create Remove Link Symlink Mkdir Rmdir Rename 289048 794043 4361 12558 25796 117739 0 GetAttr SetAttr Open Close ReadDir ReadLink VInit 64868230 759824 10701553 9891642 5042948 0 45315645 Chmod Chown Whiteout Strategy Access Mknod NewInode 409782 79612 0 4020035 0 3 0 Fsync SyncVnode LockVnode RdVnode WrVNode 0 0 0 0 0 ExtRead Extwrite FndExtAtt RdExtAttr OpnExtAtt ClseExtAt ExtStrtgy 0 0 0 0 0 0 0 or watch over time with the -w switch. I have not done any performance testing yet to see if it impacts filesystem performance by any measurable amount, so if someone does do this testing before I do, please post your results! Thanks in advance!
