Hi,
Here is an early webrev with dlstat changes. Please note that I am
*not* requesting code review. This is still work in progress with
several known(and unknown!) issues.
Webrev:
http://cr.opensolaris.org/~shri.k/dlstat_initial_webrev
PSARC case:
http://arc.opensolaris.org/caselog/PSARC/2009/364/
In this webrev, dlstat queries kernel for the statistics with explicit
ioctl. That would be changed to a kstat query instead with kstat
counters introduced for all the statistics in question. Moreover, some
of the command syntax will change. Refer "issues" in the PSARC case
noted below for more details.
Some of the sample outputs generated on Intel 10GbE setup with above
changes:
