sighandler() should take 2 arguments

2014-03-20T18:03:46+00:00

Stopping arcstat.py with ^C always ends up with error:
TypeError: sighandler() takes no arguments (2 given)

Since no special signal handling was done in sighandler(),
it's simpler to just set SIGINT handler to SIG_DFL, which
terminates the script.

sighandler() should take 2 arguments

2014-03-12T16:00:18+00:00

Stopping arcstat.py with ^C always ends up with error:

  TypeError: sighandler() takes no arguments (2 given)

This patch corrects the error by updating the signal handler
to take the correct number of arguments.

Make arcstat.py default to one header per screen

2014-03-12T15:56:12+00:00

Today arcstat.py prints one header every hdr_intr (20 by default)
lines. It would be more consistent with out utilities like vmstat
if hdr_intr defaulted to terminal window size, i.e.  one header
per screenful of outputs.

Add dbufstat.py command

2013-10-25T21:52:45+00:00

The dbufstat.py command was added to provide a conveniant way to
easily determine what ZFS is caching.  The script consumes the
raw /proc/spl/kstat/zfs/dbufs kstat data can consolidates it in
to a more human readable form.  This was designed primarily as
a tool to aid developers but it may also be useful for advanced
users who want more visibility in to what the ARC is caching.

When run without options dbufstat.py will default to showing a
list of all objects with at least one buffer present in the
cache.  The total cache space consumed by that object will be
printed on the right along with the object type.  Similar to the
arcstats.py command the -x option may used to display additional
fields.

Two other modes of operation are also supported by dbufstat.py
and the expectation is additional display modes may be added as
needed.  The -t option will summerize the total number of bytes
cached for each object type, and the -b option will show every
dbuf currently cached.

The script was designed to be consistent with arcstat.py and
includes most of the same options and funcationality.
