Hello all,

I'm a newbie in mrtg graphics. I've installed MRTG in some Debian servers and firewalls, right now mainly to monitor ethernet and memory usage. I monitor also latency in firewalls.

Last day I had to manualy stop ( simply the 'halt' comment in a shh console ) a customer's server due to a main electrical installation scheduled maintenance. The server was halted during about one hour.

After the reboot and a full functionnal check, I've looked at the MRTG statistics. I was surprised to see that values during the interruption was not null but seems to be the same as the last measure juste before the halt. Values was constant during the whole period.

It's not a real issue but I wonder to know why and if there is a smart solution to avoid these false data ?

Because each server hosts his own graph, I do not use SNMP but some short perl or bash scripts reading in /proc/*** files.

Thank for you help.
