[mrtg] Page Top OID value

[Scott Ocken]

Is there a way to put an OID SNMP GET/WALK value in the PageTop?

I have graphs for a Chiller Fluid Temp In/Out and want to put the  
Setpoint in Plain text in the PageTop.  This might change, so I don't  
want to manually put it in the PageTop.  I would be fine with writing  
a script to write the text, but I don't see a way to set PageTop = the  
output from a script.

Thanks
Scott
