These are also available in the 'mountstats-improvements-v4' branch at https://github.com/scottmayhew/nfs-utils.git v4 changes: - SteveD was not a fan of the ms-iostat and ms-nfsstat command names. Rather than think up new names, I decided to make these all sub-commands. If no sub-command is given by the user then the 'mountstats' sub-command will run by default (so any existing scripts that run older versions of the mountstats command should still work). - Rather than have 3 tiny man pages, I documented the main command and the three sub-commands on a single man page. v3 changes: - Rebased on top of the lastest mountstats version - Added exception processing to fail more gracefully when the argparse module is not installed - Corrected some issues with the man pages (filenames not italicized, unmatched braces in the synopses) v2 changes: - Changed the parsing to use the argparse module instead of optparse - Added per-mountpoint headers to the output of 'mountstats --rpc' - Revamped the ms-nfsstat command to take a variable list of mountpoints (so now mountstats, ms-iostat, and ms-nfsstat all behave in the same manner). Added -3 and -4 options which behave the same way they do in nfsstat.c. The output doesn't still doesn't match up 100% with that of nfsstat.c though (I'm just taking the first 12 characters of the operation name and converting them to lowercase to use as labels, while nfsstat.c defines its own labels, but also it looks to me like nfsstat.c is missing some operations altoegether). - Updated the man page for mountstats and added man pages for ms-iostat and ms-nfsstat. Original cover letter: -------------------8<------------------ The following patches add a couple of enhancements to mountstats.py. I also fixed a few bugs I encountered along the way. Highlights include: - added support for -f/--file to allow stats to be parsed from an aritrary input file instead of /proc/self/mountstats - added support for -S/--since to show just the changes that have occurred between the current and a previous set of statisics (works with and without the -f option) - added support for -R/--raw to generate 'raw' statistics (i.e. in the same format as /proc/self/mountstats). It's intended to be used with the -f and -S options. - implemented the ms-nfsstat command to generate client-side nfsstat-like statisics (only works with a single mountpoint) My motivation for these changes was so that I could take various copies of /proc/self/mountstats and massage them into data that I could feed into the 'report' option of Dros's nfsometer tool for scenarios where it's not feasible to run nfsometer itself (e.g. systems where we can't start with an 'idle' state (i.e. no NFS filesystems initially mounted), systems with multiple NFS filesystems mounted, and workloads that can't easily be boiled down into an nfsometer workload file or run via the custom workload environment variables).
