<DIV>>>> "James Geiger" <jpgeiger@gmail.com> 3/17/2008 8:42 PM >>><BR>> With the in and out octets, does anyone know the magic (formula) </DIV>
<DIV>> that MRTG uses to convert it to a number that makes sense? When </DIV>
<DIV>> I do an snmpget on any particular device for those two OIDs it returns </DIV>
<DIV>> some crazy number up in the billions. MRTG converts it to something </DIV>
<DIV>> (for example) like 2MB/s or what have you. Is the formula also done </DIV>
<DIV>> in perl or are there other internal conversion scripts to make it so its </DIV>
<DIV>> readable by your average human? </DIV>
<DIV> </DIV>
<DIV>Yes, the maginc formula is Delta/300. The OIDs returned are typically </DIV>
<DIV>just the number of octets that have passed through the interface since:</DIV>
<DIV> </DIV>
<DIV>a) the counter rolled over or, </DIV>
<DIV>b) the device(or snmp stack) was started</DIV>
<DIV> </DIV>
<DIV>Figuring that part out is really not that complicated. It's all the </DIV>
<DIV>other stuff (like rollover detection and normalization) that </DIV>
<DIV>make MRTG such a powerful tool.</DIV>
