[mrtg] Re: 1s in MRTG logs

[Pavleck, Jeremy]

I doubt the 1 can be considered reliable.
Here too I occasionally receive a 1 on as the data returned on some
graphs - in my situation this is usually due to there being a probably
with on of the OIDs MRTG is accessing (I perform a lot of math functions
in my graphs, adding mainly). Some of my targets include adding together
up to 10 OIDs and if it's missing one or two it skews the results

Subject: [mrtg] 1s in MRTG logs

Hi All

I have sometimes observed in MRTG log files that data values are 1, and
in logging several things (e.g. CPU utilisation, free memory, disk busy
% and so on) they are all 1 at the same time. Is this "1" value
trustworthy? I understood from the documentation that -1 is supposed to
be used if data could not be obtained. Does MRTG convert -1 to 1 because
it doesn't handle negative numbers? Is there more documentation
somewhere that covers this?
