[Orca-users] Re: page scan rate always zero -- sar says otherwise (Solaris 2.5.1)

[Blair Zajac]

OK.  We were close.  Here's the real solution.  Change

  put_output("scanrate", sprintf("%8.3f", pvm.scan));

to

  put_output("scanrate", sprintf("%8.3f", pvm.scan + 0.0));

I've tested this and compared the output of
se -DWATCH_CPU orcallator.se 5 with sar -g 5 1000
and they are very similar.

I'll put out a new orcallator.se release with this fix.
