Description:
The server status variable 'Uptime_since_flush_status' does not exist in 5.1.28.  I find
it in 5.0.67.

I do not exactly know whne it was introduced (it is not in 4.1), but it is badly missing
in 5.1.

Interpreting SHOW (GLOBAL) STATUS is hopeless without knowing 'Uptime_since_flush_status'

How to repeat:
show global status like 'uptime%';

and it is not in 6.06 either!

It is missed even in 5.0.66a. Based on this page,
http://dev.mysql.com/doc/refman/5.0/en/releasenotes-cs-5-0-37.html, I assume it was added
by a patch from Jeremy Cole and may be available only in Community versions. 

Anyway, it should still be available in 6.0.x (and 5.1.28, that has no differentiation,
yet).

Also, I can't find it in:
5.0.42
5.0.58
5.0.68
5.0.601

All are enterprise versions.

Any news about this bug?

Couldn't reproduce with more recent package.

OK .. I find it now in 5.1.31.

Anyway I open again becausee I find the term 'more recent version' used in the reply
non-professional.  Please always refer to *exact version no.'s*.  In which version did
YOU find it?

If I posted a report and I did not describe the exact version, I would be corrected!

GGRRRRR!!!

.. and also please refer to where in changelogs this is documented!

This is critical for our application and for our customer support!

This
(http://dev.mysql.com/doc/refman/5.1/en/server-status-variables.html#statvar_Uptime_since_f...)

"Uptime_since_flush_status 

The number of seconds since the most recent FLUSH STATUS statement. This variable was
added in 5.1.24"

.. is not true.  Or there was a regression between 5.1.24 and 5.1.28 that has been
corrected 'silently' (what means without proper documentation)!

also 6.0 documentation is wrong - or also here there was a regression!

http://dev.mysql.com/doc/refman/6.0/en/server-status-variables.html:
"Uptime_since_flush_status ... This variable was added in 6.0.5" .. but bug was confirmed
with 6.0.6!

I am not impressed by the effort here that seems to be more focused on closing reports
rather than than doing proper research and provide correct information and documentation!

... and I also think that Tomer would like to know (as I would) if this variable is/will
be implemented in ENTERPRISE servers!

Opening again.  Documentation is incorrect!

Documentation is perfectly correct. It refers to when this feature was added to the source
code. There are no official production-ready packages that don't include it.
