I'm trying to monitor the signal strength on a Ceragon FibeAir 1528I. Is
there a way to get MRTG to accept the negative values I'm getting from the

# snmpget public . .
enterprises.2281. = 17
enterprises.2281. = -64

Here is the config stub I'm trying to use.

options[radio_local_signal]:  growright,nobanner,gauge,nopercent
Target[radio_local_signal]: . at radio:
Directory[radio_local_signal]:  radio
MaxBytes[radio_local_signal]:  140
Title[radio_local_signal]:  Local Signal Levels
YLegend[radio_local_signal]: db
ShortLegend[radio_local_signal]:  db
LegendO[radio_local_signal]:   TX db:
LegendI[radio_local_signal]:   RX db:
PageTop[radio_local_signal]:  <H1>Local Signal Levels</H1>
