[mrtg] Re: What happens after an outage?

[Eric Van Tol]

The behavior is supposed to be that the last known value is used, unless
"unknaszero" is configured.  Unfortunately, as you mentioned in your
last email, 2.10 appears to have introduced an annoying spike in the
graphs, which no one seems to have a resolution for.

Subject: [mrtg] What happens after an outage?

If the machine running mrtg is down or cannot cummunicate with targets
for 
an extended period of time, is it natural for the rates plotted to spike

when mrtg comes back?

This appears to be the behavior I'm seeing in our v2.10.8 installation -

very severe rate spikes on all graphs when a nonresponsive mrtg server
is 
rebooted.
