Jochen,
Thanks for your reply! I read all of the online Tutorials and
the manuals yesterday and I feel I'm ready to take a stab at dumping
the SnmpCollect data to an RRD. The only problem I'm running into is
SnmpCollect already figures out the the per/second value (as a float
value), should I do the math in a script to set the value back what the
devices says then store that and let rrdtool figure out the difference?
Or do you import exactly what snmpcollect spits out?
For example:
snmpcollect looks like this;
11/17/00 05:33:04 someserver.dot.com 1234.0 974453584
974457184
Do you store the "starttime" and the "float value"
or do you store
the "starttime" and "Value * (StopTime - StartTime)"
