[mrtg] Re: Graphing total line utilization

[JeremyP at psi-cu.com]

1.You might try, but the manual says that MaxBytes is used for the Y
axis on unscaled graphs, so this may not work.
1600000/8 = 200000
ABSMax[_]:200000 
Unscaled[_]: wmy

2.MaxBytes is the actual red line that is graphed.
1544000/8=
Maxbytes[_]: 193000

3. Most T1s are full duplex, so you may not need this, but here is the
info from the reference page
---------------
Multi Target Syntax

You can also use several statements in a mathematical expression. This
could be used to aggregate both B channels in an ISDN connection or
multiple T1s that are aggregated into a single channel for greater
bandwidth. Note the whitespace arround the target definitions. 
Example:

 Target[ezwf]: 2:public at wellfleetA + 1:public at wellfleetA
              * 4:public at ciscoF

Subject: [mrtg] Graphing total line utilization


I'm looking to tweak my MRTG graphs a bit to display the following:
 
1) Set fixed graph height
For example, I'd like the height of my T1 WAN link graphs to be hard set
to 1600k
 
2) Show a horizontal red line at line speed
In the above example I'd like a red horizontal line @ 1544k
 
3) Add a third variable for total throughput
Currently my MRTG is graphing in and out bits. I'd like a third variable
to display in+out so I know how close I am to maxing out my WAN link.
 
Any help would be greatly appreciated.
 
Thanks,
