[mrtg] Differnet Poll Values for Similar Type of Interfaces

[Sean Cheesman]

You can't poll negative values.  Maybe someone can offer an alternative, but MRTG itself cannot handle a negative polling value.

Hi,

I am observing differnet poll values for POS 0/0/0/0 and POS 0/1/0/0 while monitoring optical power (DOM). The output shows following tx/rx power
1). Tx power = 0.4930 mW, -3.1 dBm

2). Tx power = 0.5400 mW, -2.7 dBm

The polled values are:

For 1),
1240390321 2538 2538
1240390321 2538 2538 2538 2538
1240390019 2538 2538 2538 2538
1240389900 2538 2538 2538 2538
1240389600 2538 2538 2538 2538

For 2),

1240390321 45 45
1240390321 45 45 45 45
1240390019 45 45 45 45
1240389900 45 45 45 45
1240389600 45 45 45 45

Plz suggest if there is something wrong in the cfg as both the interfaces are using same OID on the same router.
