[mrtg] Re: maxbytes

[Alan Rader]

Well, at first I did just set Maxbytes to a lower value and that did not
work, so some posted to try Unscaled, so I tried adding that and no luck.

Well from my (limited) experience, it sounds to me like you should be
lowering your MaxBytes. When a value comes in greater than MaxBytes it would
be discarded. To not see any spike greater than 2000, set your MaxBytes to
2000.

Unscaled won't be what you're after - in an unscaled setting, the graph
plots with the y-axis going up to maxbytes, no matter what the current
values are. Unfortunately dynamic scaling just has these things to deal
with. Undynamic : sometimes flat line graphs. Dynamic : sometimes the graph
is forced out of alignment by a large data spike.

Perhaps other group members can suggest alternatives?

Well, I have a spike that went up to 2100K and normal usage is down around 
100k.  I would like the graph to stay down at that max even if there is 
another spike over it.  I put in the maxbytes[xxx]: 100000 and added the 
Unscaled[xxxx]: d since I only want the day graph like that.  I made a small

change in one of the title just to make sure the new cfg took when I 
restarted it and it did, yet the graph did not change. 
  
Do I have to delete the .png files next or should it adjust on its own? 
  
Thanks

Not sure what you're expecting to see? Do you want to see the graph only 
scale up to 2000 or go all the way to 10,000 and show the spike 1/5 of the 
way up? 

Firstly, I would try removing the .png files and let the process rebuild new

ones after the next poll. (Back up the files in case this doesn't work, of 
course.) If your config file is OK this might be the simplest way to do 
things. 

Next, look at the Unscaled option in cfg files.. (from manual) : 

Unscaled 

By default each graph is scaled vertically to make the actual data visible 
even when it is much lower than MaxBytes. With the Unscaled variable you can

suppress this. It's argument is a string, containing one letter for each 
graph you don't want to be scaled: d=day w=week m=month y=year. In the 
example scaling for the yearly and the monthly graph are suppressed. 

Example: 

 Unscaled[ezwf]: ym 

hope this helps.

I set my maxbytes to 10000 and I have a spike that only goes to 2000, so why


will the graph not resize?  I stopped and restarted the service running that


config.
