[mrtg] Re: OID bridge Proxim

[Melih Turan]

Thanks for the solution, however I am not using rrd. But since I am using a
minus sign the result  in the log file is true. On the other hand, I
configure the config file as to get only the Signal part. However it still
does not give an expected graph.

Unfortunately, MRTG doesn't like negative numbers if you are using the
default log format. If you switch to using RRD as the log format (just put
"LogFormat: rrdtool" in your config) you'll be able to record negative
values. I had to tweak the range on my rrds after they were created.

It looks like I used a range of -100 to 50 for SNR. The command looked
something like  this.

rrdtool tune radio.cfg -i ds0:-100 -a ds0:50 -i ds1:-100 -a ds1:50

Of course, then you need to figure out which CGI frontend you want to use,
and that is a problem in itself. I appear to be using mrtg-rrd.cgi, but I
don't remember if I had to make any changes to get it to work (it's been a
while.)
