Hi All,

I'm using MRTG 2.9.10 on NT, monitoring several Cisco routers and switches. Everything seems to run just fine with one exception; graphs do not show any data from midnight to about 6AM. We can see increased load at around 10PM (nightly maintenance starts).  At 00:00 all lines go flat (quite sure traffic still there). Early in the morning graphing resumes normally. Same problem for all interfaces on  different routers.

(mrtg logging shows no errors during this period.)

Here is an extract from the cfg
