[mrtg] Re: Creating Graph

[PAUL WILLIAMSON]

Yeah, something like that.  Keep in mind that unless you are 
putting in the exact information MRTG expects, rateup may
die a horrible, big, flamming deathball.

I'm not saying you need to run RRDTool to do this.  You should 
use the external program call function built in to MRTG.  When 
you start manipulating the log files outside of the MRTG process, 
don't expect the process to behave well when it comes across 
an unexpected situation.  This might include values not at the 
step interval, locked files not available for reading, incorrectly 
formatted numbers, rolling numeric averages computed 
incorrectly.

All I'm saying is that you may not have a perfectly fine 
MRTG server if it runs into a situation for with you have not 
accounted.

I am not using RRDTool, I have an existing server that has been running
for
close on to 4 years now. I don't fix what isn't broke.

So in this case, if I have created "myownlog.log", I could just call
#rateup.exe myownlog.log ?
