<DIV><FONT face=Arial size=2><SPAN class=380550515-02101999>Hi
All,</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=380550515-02101999>I have been
manipulating mrtg successfully for the last couple of months and have become
rather attached to it. I have come across a bit of strange behaviour recently. I
graph 2 links from one location to another, both seperately and added together.
Untill a couple of days ago the math worked logically. However in the last
couple of days the graph of the 2 links added together looks as if there are
lots of flaps on the circuits while the individual graphs look no different than
they ever have. </SPAN></FONT><FONT face=Arial size=2><SPAN
class=380550515-02101999>Below is the configuration of the 3 objects. I run
the same config apart from the IP address and name on the interfaces at the
other end of the links with the same behaviour. Mrtg is on the same subnet as
the nearest router but on the other side of a couple of switchs. Mrtg runs
seemingly fine for other objects including those very much further down the
track and others that I run math on. I have also tried test runs of the same
configuration on different versions and installations of Mrtg on different
platforms with exactly the same effect. I include the weekly graphs that mrtg
makes. I would very much appreciate any input on this behaviour as this combined
graph, which I am beginning to suspect may not be Mrtg's
fault.</SPAN></FONT></DIV>
