[mrtg] Re: Aggregate interface monitoring and the MaxBytes parameter

[Koelstra, J. (Jan)]

Something to keep in mind: This method works only as long as the
summarized traffic rate is always below the rollover value of each of
the individual ports....

}I am creating a separate instance I guess. I have a separate 
}.rrd file for each blade. I have a separate config file with 
}high (>=5000) reference numbers that are aggregates. For example: }
}Target[switch_5000]: 40:community at switch + \
} 41:community at switch + \
} .
} .
} .
} 64:community at switch
}
}for a 24 port blade. Is this the 'proper' way to accomplish 
}the task? Is there a better/faster way? I am always interested 
}in creating less load - I am monitoring several thousand ports. 
}

That's as good a way as I can think of. I've often wondered what the
total traffic input/output traffic was across a single device. So many
times the "cpu %utilization" or "backplane %utilization" 
OIDs are bogus, or only pertain to a functional 'layer' of the 
device. It's very difficult to come across accurate utilization numbers.
