[mrtg] Value below 0 problem

[Graaff, Ben van de]

Hi all,
 

I have al small problem and hoping for somebody to help me.

 

I have a mrtg script with is getting data from our Cisco DWDM metro
switches.

I am interested in the optical power health.(I have got the OID)

 

In the mrtg graph i am not getting any values.

 

 

When i try to get the OID with GETIF i got a value back that is below 0
(nullobj).

How do I tell mrtg that the value it is getting is a negative value.

 

Thnx,

 

Ben van de Graaff.
