but oops, i am realizing that on snmp values what i’d really like to create is minus (-)
my questions is ‘how to deal with these things, i’d like to graph power level on each wireless radio i have ?’

thanks

The was some problems with negative values on The Dude v<=3.6 (graphs where not drawed correctly). But on 4.0 there are no such a problems. So if you are dealing with negative SNMP values you should use v 4.0

In any case, when you are in doubts whith some features you always can try and see…

Thanks for the response,

i made some error typo on probes, yes it’s working perfectly (using latest the dude version 4.2 beta)

For anyone else who may still be using 3.6 just multiple your oid by a -1 and your graph will graph as positive numbers. This way it looks proper in the graph.

Example of Canopy power level graph:

oid(“iso.org.dod.internet.private.enterprises.mot.whispRoot.whispProducts.whispSm.whispSmStatus.radioDbmInt.0”)* -1
