[mrtg] Re: Bits, Bytes and Bandwidth.

[Dave Jones]

I know a couple of these:

1 - In your config files, for each device you want to change to bits instead
of bytes, put this in:
Options[myrouter]: bits.  The data won't be lost, just re-graphed.

2 - Put in AbsMax[myrouter]: 8000 (that's 64000 bits / 8 to equal bytes.
You can then put in MaxBytes[myrouter]: 4000 (or whatever you want, the 4000
equals 32000 bits).  So if you want to have a distinguished line showing you
when your line goes over 32k.

3 - Can't help on this one, as I haven't tried it.

Hi,
    I use mrtg to monitor traffic out of my CISCO router and it works fine.
Now I want to make certain changes to my mrtg graphs that get drawn(I.e
daily, weekly etc). I am not a programmer and though I an using mrtg since
the last 4 months I haven't changed anything. Also I get stuck very easily
so please be as specific as possible. Here are my problems:
 
   1)  Right now all the plots are in bytes/second(B/s). I want this graph
to be plotted in bits per second(bps or b/s).
   1a) If this can be changed and is changed, will I lose all the data
previously collected?(4 months).
 
   2) My Link is 64Kbps so I want the ceiling of the graph to remain at say
64Kbps and the percentage of the maximum,last,current in/out to be a
percentage of 64K and not the maximum speed of my router port. Again if this
can be changed and is changed, will I lose all the data previously
collected?(4 months).
 
        Even if I lose my data I don't mind keeping two versions running for
some time.
 
3) I have sixteen switches on my network and I have all NT
Workstation/Server Laptops. I want to know which computer is connected to
which port. The Laptops move frequently. The switches are all
Baystack\Nortel Networks. I tried using CAMMER but it works only with CISCO
equipment. I changed the OID in the cammer.pl file but that doesn't help.
 
 
any help will be really appreciated.
 
 
Thanks,
Chetan
