[mrtg] Re: Bits and bytes

[Jeroen Geusebroek]

Ok, i finally fixed it with the Maxbytes * 8.

I am still confused about the interfaces this router has.

Thank all for the help.

Regards,

Jeroen

Is this the number on the first line of the log?  If the interface 
doesn't have much of a load, you won't see much.  

Remember, mrtg does rate of change over a given period of 
time.  If the rate of change is too little vs. the time that has 
elapsed, there won't be much to look at.

A rough explanation would be that if you had 300 bytes pass 
through the interface in 5 minutes, it would show 1 byte/s 
during that 300 second period.

300 bytes/300 seconds = 1 byte/sec

This does not account for the fact that you will most likely not be 
able to sample the interface at EXACTLY 300 seconds, so then 
the MRTG normalization kicks in, which will open up a whole 
'nother can of worms...

Alright i am trying this.

But to get this straight, wouldn't this just only affect the MAX amount
of
Bytes that come in? Lets say mrtg checks snmp and gets a value of
100(which is bytes for this device) how does mrtg handle this?
