Hi, I just was wondering how RRD would handle router reloads. Currently i'm monitoring some cisco routers (interfaces, memory etc.). The problem i had is that from time to time i can see some peaks in my graphs and i couldn't find a reason for this peaks. First i thought there were some warps of counters but i was told that RRD can handle those warps. SO i looked closer to the database and now i'm sure that the peaks occur every time a router reloads. The peaks are really confusing me because the graph i attached is from a physical 2 MBit line so there is no way to have a 50 MB peak on this line.
Did anyone made the same experiences like i did ? I think that the problem could be solved when there were some min and max values but the capacity of the leased lines is changing quite often and i don't want to set all the min and max values each time. Is there another way to get rid of this problem ? Is it possible to let the RRD check if the actual value of octets is smaller than the last one stored in the database and if so just put a NAN in the database ? This would cause a missing value and also counter warps won't be handelt with this change but in my case this doesn't occur very often so i prefer loosing one data sample instead of makeing the hole graph unusable. Is there a simple way to modify the RRD Source ? Anybody did it already or does anyone have a better solution ? I just attach the graph and the datafiles in kind of someone want to look at the datas. Thanks for the feedback.
