Stephen ,
this is what i have understood -
mrtg works behind the scene , getting the required parameters from SNMP which 
is on the machine you are trying to monitor ..
rrd tool is organising this into an rrd database which stores the information 
retrieved by mrtg , in a format very different from the original logfiles that 
you got from simple mrtg ..
14all reads this rrdtool database to generate the graphs ..
I  was --> 
using mrtg to view the cpu utilisation of the 2000 server here
the configuration file worked fine and i got the graphs expected.
but as anybody might know for cpu utilization i wanted a slightly faster 
interval .. so i decided to switch to the mrtg-rrdtool combination 
Now my problem is -->
-i am using the original mrtg comfiguration file , with whatever slight changes 
for the rrd tool 
-the config file is running ok
-my rrd database is being updated with whatever information every 3 minutes , 
as set in the config file
-but when i try executing the cgi file from my web browser i am getting every 
thing but the graphs
about your problem you are supposed to manipulate the counters likewise .. but 
i have no clue as to how , exactly ..
One fo the users in this mailing list used the method below to graph the cpu 
utilization , i am not using anything like that , but i thot that might help 
you in u r prob ..

Hello
Am I wrong in assuming that if I do this math I will be correct?:
 ssCpuRawSystem + ssCpuRawUser + ssCpuRawIdle = Total
 then
 (ssCpuRawSystem / Total) * 100 = % of System utilization 
 
Is that correct?
----
yes , it seems everybody knows way too much .. and maybe we missed the starting 
gun ..
take care
