Below are the main architectural issues from the PSARC/2009/364
inception review,
to be addressed before the commitment review.
- Use of kstats as underlying stats, rather than a new way.
The project team will need to justify why kstats aren't suitable for
accumulating and reporting the counters needed to be extracted
by dlstat and flowstat
- Drop the verb (show, show-history, reset) from the subcommand, replacing
them with simple option. This is consistent with the rest of
{vm,io,net,..}stat commands in the system.
- Multiple issues with reset stats:
- The loss of information accumulated since boot time may hurt the
diagnosability of problem with flows and links.
- The action needs to be privileged.
- suggestion: move the reset subcommand to {dl,flow}adm, with expected
effect of resetting the state of the datalink/flow, which includes the
usage statistics thereof.
- Clarify change of interface commitment level of existing show-* statistic
related subcommands of dladm and flowadm, from 'committed' to
'committed obsolete'
- The '-o' (+ or -) option, Be consistent with the rest of the commands in
general, (ps, dladm etc.). Use -o with the exact list of columns to
be displayed.
- Before commitment, the man pages need to be updated to reflect the changes
from the inception review.
