[Orca-users] Data Accuracy problem or is it averaging?

[Santana Fernando]

	It gives me the following errors and no rrd files are generated.

 Creating RRD `/opt/orca/var/orca/rrd/orcallator/o_web3/gauge_inod_ref_per_s.rrd'.

Santana,

If you want to remove consolidated data, I would completely remove the
consolidations.  I would modify lib/Orca/Constants.pm to have something
like this;

use vars         qw(@RRA_PLOT_TYPES @RRA_PDP_COUNTS @RRA_ROW_COUNTS);
push(@EXPORT_OK, qw(@RRA_PLOT_TYPES @RRA_PDP_COUNTS @RRA_ROW_COUNTS));
BEGIN {
  @RRA_PLOT_TYPES = qw(yearly);
  @RRA_PDP_COUNTS =   (                1);
  @RRA_ROW_COUNTS =   ( 3*365*24*2400*12);
}

Let me know how this works.

It'll probably be really slow this way though.

Best,
Blair
