[rrd-users] perfdata not correctly parsed ?

[Nicolas - rrdtool]

Hi,

I'm using rrdtool in centreon, trying to graph the output of the 
check_snmp_storage.pl plugin.

Perfdata is correct, according to me :

'/mnt/disk1'=4149395MB;4873983;4978800;0;5240842 
'/mnt/disk2'=3938774MB;4873983;4978800;0;5240842 
'/mnt/disk3'=4244850MB;4873983;4978800;0;5240842 
'/mnt/disk4'=4267812MB;4873983;4978800;0;5240842

According to the perfdata guidelines 
(https://nagios-plugins.org/doc/guidelines.html#AEN200), the UOM is 
correct :
  10 : UOM (unit of measurement) is one of:
    d : B - bytes (also KB, MB, TB)

But the graph displayed has divided the values by 1024/1024. See my 
question on this forum for pictures :

http://forum.centreon.com/showthread.php/16199-check_snmp_storage-pl-and-graph

I then modified the plugin so that it outputs raw values, the new 
perfdata is the following :

'/mnt/disk1'=4354426724352B;5110741642076;5220650064486;0;5495421120512

But now, the graph doesn't recognize the values (too big ?), as it says 
"-nan'.

What solution do I have now ?

Nicolas
