WithPeak MRTG Graphs

[d0ors]

How can I get equivalents of MRTG WithPeak graphs ?

With peaks graph included the following info in weekly, mon, yrly graphs..

Maximal 5 Minute Incoming Traffic
Maximal 5 Minute Outgoing Traffic

Any pointers would be appreciated.

Please find the attached picture..

Legend :

GREEN ### Incoming Traffic in Bits per Second
BLUE ### Outgoing Traffic in Bits per Second
DARK GREEN### Maximal 5 Minute Incoming Traffic
MAGENTA### Maximal 5 Minute Outgoing Traffic

Thanks

Easy, if you want maximal for both, add a line with the MAX inbound RRA, and another line using the MAX outbound RRA. If you want just the max of whichever is greater, then I would have to test. Maybe the if CDEF function would work for this version of Cacti.

Thanks.

One more clarification, the MAX value represents the 5 min average value polled or an instantaneous max ?

[TheWitness]

Well, on the 5 minute graphs, it is redundant, however on the Weekly, Monthly, and Yearly it is the MAX average within the interval specified.

In other words, in the weekly, it will be the MAX 5 minute sample. In the monthly, it's the MAX 30 minute average and so forth.

Hi, I have some problems to display mrtg-like peaks over my graphs. As you suggested in previous discussions, I add a LINE1 object into "Interface - Traffic (bits/sec)" under "Graph templates" section and I set MAX as Consolidation Function, but this doesn't solve the problem.

In particular (see the attached graphs images), the red line (peak for outbound traffic) is always lower than outbound traffic. I tried to change some options of line object (such as CDEF functions or GPRINT type) without success.

Could you give me any suggestion please?
Any comment will be appreciated.
Thanks.

I added this to one of my graphs earlier, it looks like it is graphing bytes instead of bits, hence the lower value. I know you have tried changing CDef items but to fix this try the following:

Go into your new item in the graph template (Your Line1)
Set the CDEF to: Turn bytes into Bits
Save and Save.

Good Luck.

Yeah it looks like a bytes to bits issue.

Thank you very much. With your answer I resolve my problems. Now I can correctly display peak's data over my graphs.

I just can't figure out 2 things:

1.Why weekly's max value is not shown in monthly graph ?
2.Why the value are not match in monthly graph and gprint?
The graph and the configure are attached, and my Cacti version is 0.8.6h.

Any idea will be welcome.

Consolidation.

Read bout it in the documentation site or rrdtool's website. You can increase the history (aka rows) rrd files store, with increased disk space, of course.

You really should upgrade cacti to 0.8.6j + patches or consider 0.8.7a.

[foxfriend]

All right, I'v upgraded my Cacti to 0.8.7a, and the problem still remained.
So, I guest it's about increase the history rrd files store by increasing disk space. But I have lots of it:

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 152965700 7597160 137598304 6% /
/dev/sda1 101086 11572 84295 13% /boot
none 1037912 0 1037912 0% /dev/shm

My Cacti located at /etc/www/html, which only used less than 6%.

The Problem is, how should I increase the history rrd files store?

Thank you.

[BSOD2600]

Did you read about how to increase the rrdtool history in the documentation site yet?

[foxfriend]

I think I got it. Thanks again.
