I would like peaks in the graph, but I can't figure out how!

[mordien]

Hi all,

First of all, thanks for a great application. I've recently installed it and it works very well!

If I look at the last 4 hours I show the peaks, the problems come when I "zoom out" to last day, or look at the weekly/yearly graphs when the peaks aren't shown. Is it possible to also show the peaks in the same graph (daily, weekly, yearly)?

I've searched the forums and I see that others have asked for the same thing, but haven't found any real answers and I must admit that I'm not sure where to start. If anyone would have the time to make an easy "n00by" guide, I'm sure it would be very appreciated from several readers.

I've attached a pic as an example how I it could look like, if possible. Same thing for monthly/yearly.

Thanks in advance all !

As I understand your question, this is a kind of "averaging out" sharp peaks when displaying a larger timespan. This behaviour will change, if you do not use AVERAGE but MAXIMUM consolidation function. See more about this in the first few links of my signature

Thanks for your reply!

The standard graphs does average out the peaks and that's ok. But I woul d also like to see the peaks in the weekly/monthly/yearly graphs!

If I take a look at the default weekly graphs, even if we have peaks at 260Mbit for 10 minutes each day it will only show as 80Mbit or so because it's an 30 min average.. if it is possible to also get the peaks that would be great.

We are trying to use the graphs for traffic planning and need the peaks.

Thanks

As I tried to say: This is possible. But the "standard" graph templates do use the AVERAGE consolidation function. This will store the average of 6 values. But if you change this (or build a new template) and use the MAXIMUM consolidation function, the the max value of those 6 is stored. So you will see the peak again.
Please have a look at my posts in the signature, especially at the "Max" one

My apologies lvm, I wrote the answer before checking out your link. (was a bit frustrated )

I'll try it out tomorrow at work, it seems that it's exactly the thing I've been looking for!

Thanks for your help!

It worked great with the FAQ you've made!

I did get the "ERROR: invalid rpn expression in: ,-1,*" error, but it was easily fixed by just erasing that info from the graph. It wasn't needed either way.

Again, thank you for your help!
