[Orca-users] Plot with if condition in value

[tim.schmeling at bechtle.com]

Hi,

i have different machines and like too monitor the disk i/o.

on my xen-Guests i have disks like: /dev/xvda1 which contains it´s data at 
"disk_rd/s", etc.
on my xen-hosts i have disks like: /dev/sda1 which contains it´s data at 
"disk_rd/s", etc.
Last but not least i have some HP machines, and there i have disks like: 
/dev/cciss/c0d0p1 which contains it´s data at "part_rd_cciss/c0d0/s", etc.

I habe modified the "procallator.cfg" on my orca master machine, but it 
does´t work.
No values are monitored. When i use "part_rd_cciss/c0d0/s" without the if 
contition, it´s worked and the values are plotted. It´s the same, when i 
use "disk_rd/s".

Can anyone help me, to configure the two data values in my plot?
