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).
