[mrtg] Feature Request

[Jeff Liebermann]

Can someone give me a pointer (or do the work) on tweaking
the mrtg Perl code so that *MISSING* data (i.e. the router
goes offline or the server stopped polling for SNMP data) or
gaps in the data show up as a zero on the graph instead of
a straight line with a value of the last recorded number?

The problem is that I was using MRTG to do SLA monitoring
of a telco connection.  The line went down but the MRTG
graphs showed that there was still traffic (constant value
starting from last recorded number).  Trying to convince
PacHell that it was broken was no fun when the graphs showed
that it was still alive.

I would do this myself but I'm the worlds worst programmer.

Having the graph go to zero would also solve the problem
of monitoring Ascend P50/75/130 SNMP which like to have OID's
disappear when the router drops the connection.
