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. Kais.

Subject:	dlstat and flowsat

Submitted by:	Shrikrishna Khare

File:		PSARC/2009/364/opinion.txt

Committee:	Kais Belgaied, Garrett D'Amore, Sebastien Roy, Glenn Skinner.
		
Product Approval Committee:

1.  Summary

This case delivers two main sets of changes:
- Splitting of the data link level observability features for live and
  historic usage statistics outside the administration tools dladm(1m)
  and flowadm(1m)
- Enrichment of the set of counters with finer grain visibility over
  the hardware resources usage and network scheduling information.

2.  Decision & Precedence Information

The project is approved as specified in reference [1].

The project may be delivered in a patch release of Solaris.

4.  Opinion

Much of the commitment review discussion was about clarification of
the obsolescence requirements for this project.

The interfaces that were already shipped with Solaris10 Update needed
to be marked obsolete, following the regular EOF process.

Other interfaces, such as flowadm(1m) and dladm show-vnic -s were not
yet picked by a supported release of Solaris since the feature that
introduced them (Crossbow - PSARC/2006/357) was not back ported.
From a point of view of the Solaris product release train, those interfaces
can be changed or deleted without notice.
However, these interfaces made it into the last release of
OpenSolaris 2009.06,  and were documented in that release's man pages.
To the extent that OpenSolaris 2009.06 can have long term support,
flowadm(1m) and dladm show-vnic -s (etc) need to be marked obsolete in the
man pages of the next OpenSolaris release.

The newly Obsolete interface should be listed there, no?

There's a garbage '>' character in there.  Otherwise, this looks good to
me.

It was pointed out to me that this was due to a bug in my mail client
(not to name names, but it's Evolution!). ;-)

1.  Summary

This case delivers two main sets of changes:
- Splitting of the data link level observability features for live and
  historic usage statistics outside the administration tools dladm(1m)
  and flowadm(1m)
- Enrichment of the set of counters with finer grain visibility over
  the hardware resources usage and network scheduling information.

2.  Decision & Precedence Information

The project is approved as specified in reference [1].

The project may be delivered in a patch release of Solaris.

4.  Opinion

Much of the commitment review discussion was about clarification of
the obsolescence requirements for this project.

The interfaces that were already shipped with Solaris10 Update needed
to be marked obsolete, following the regular EOF process.

Other interfaces, such as flowadm(1m) and dladm show-vnic -s were not
yet picked by a supported release of Solaris since the feature that
introduced them (Crossbow - PSARC/2006/357) was not back ported.
From a point of view of the Solaris product release train, those interfaces
can be changed or deleted without notice.
However, these interfaces made it into the last release of
OpenSolaris 2009.06,  and were documented in that release's man pages.
To the extent that OpenSolaris 2009.06 can have long term support,
flowadm(1m) and dladm show-vnic -s (etc) need to be marked obsolete in the
man pages of the next OpenSolaris release.

yet picked by a supported release of Solaris since the feature that
introduced them (Crossbow - PSARC/2006/357) was not back ported.
From a point of view of the Solaris product release train, those interfaces
can be changed or deleted without notice.
However, these interfaces made it into the last release of
OpenSolaris 2009.06,  and were documented in that release's man pages.
To the extent that OpenSolaris 2009.06 can have long term support,
flowadm(1m) and dladm show-vnic -s (etc) need to be marked obsolete in the
man pages of the next OpenSolaris release.
