RRDTool Traffic Graph Tutorial - Extremely easy to follow !

[MMCM]

One thing just kills me. All router power goes to make those crapy lines and i havent installed nothing except samba, wwwphp, dropbear, nano. Refresh goes every 5 min and still :/
If that wont help i will say byebye to rrdtool.sh and find other way to generate stats

You should use the older rrdtool version 1.0.50, it's about 10x faster generating graphs. The output is not that pretty because it doesn't use antialiasing.
Additionally, stop generating graphs you never look at. I use cgi scripts with lighttpd on openwrt (worked with thttpd on olegs fw too), and graphs are generated on demand only.
I do sample data every minute with traffic of 4 interfaces, cpu load and cpu usage and my average cpu usage is below 5%.

Well i used new package and it was taking all the time about 80%-90% cpu so if you do the math there isn't a lot of space for anything else [i was lagging out from time to time]
Anyway where i can't get that package ? I'm kinda new to linux but most of things im learning quite fast - just need some directions xD
Well i found smth usefull tho i dont have a clue which build i should use:\
http://rpmfind.net/linux/rpm2html/se...?query=rrdtool

rpm are for PC base linux distros, you won't be able to use those on your router, you need to look for *.ipk packages.

Read some of the tutorials at macsat.com first.

Unfortunatly the http://ipkg.nslu2-linux.org/feeds/op.../cross/stable/ feed contains only the newer version of rrdtool. When I was still using olegs firmware, I downloaded an old package of rrdtool from somewhere, but I don't remember where.
OpenWrt kamikaze feed do contain both versions of rrdtool, so you can decide what you want :-)
You could try to download that .ipk and extract the required binaries manually, but I don't know if that will work.

But anyway, switching from background generated graphs to cgi/runtime generated graphs will free your router from a lot of work.

hmmm?

Since I am generating many graphs (cpu load, network, cpu usage (%)), it eats a lot of CPU time for nothing (most of the graphs will never be looked at).

When I read about rrdcgi, I decided to give it a try.
In theory it works well, but in practice, it takes some time just to generate one graph (dependent on size), so the cgi-script is mostly killed before it finishes.
It seems the CGI_TIMELIMIT is set to 30 seconds, not the typical value of 300.

Did this occur to anybody else?
It's bad you have to recompile thttpd to change this.
Is there a version with a higher value of CGI_TIMELIMIT available?

The source path for php-thttpd in the unslung ipkg list file points to the www.acme.com website with the original source, not the one with configs & scripts for the specified package. It would be fine to have the customized code available.

Hi I currently use mrtg to create graphs every 5 min. There is extension for it so it will only create RRDtool database and then you can use cgi script from their web site to generate graphs but it didn't work for my it complained about
some value in dynaloader.pm line 80.
Anyway any chance to share how can we get graphs for cpu and load?
thanks

Hi all

First of all, I must say, this is a very nice forum

Got 4 wl-500gP from work, an started to play with 'em... And the howto's are easy to follow, and i think, that it took me about 45-60 min to setup my final one (3 others are still working, but not 100%).

Now - The thing is, I would really like to have some sort of fealing with my diskspace on my philips 320GB USB drive.

Is there a tool allready for this or is it from scratch

[raas]

What do you mean with 'fealing'?

do you want to access the usb disk ?

[al37919]

another approach may be usage of a small lcd monitor to display the current memory/hdd consumption

[trider]

well, some read-out of some sort, could be nice...

Could be a graph or just displayed in numbers. The thing is, I don't know how to log the information. If I ssh to my router, I can type in 'df -h', and the data is displayed.

But how to get it on my http page of net, mem and CPU graphs, I do not know...

Hi Everybody,


I have installed successfully RRDTool and I set it up in crontab. I use rrdrun.sh shell script in /opt/etc/cron.5mins directory to run /opt/usr/bin/rrdtool.sh.

If I list running processes by ps command, I notice a weird thing: I see many rrdtool processes. Here is the result:

etc.


Does anyone know what this strange behavior is?

[Chillout]

check out the rrdgraphs for traffic somewhere on this board. it demonstrates how you can log data.

[wirespot]

Also see this. There's a script there which contains an example about how to graph disk space. But I hope you know your rrdtool (and bash) 'cause that script is not for the faint of heart.

[poiu]

I try your script copacup and i get : -sh: rrdstorm.sh: not found when i run it.
#-------------------------------------------------------------------
# configuration
#-------------------------------------------------------------------

RRDTOOL=/opt/bin/rrdtool
RRDUPDATE=/opt/bin/rrdupdate
RRDDATA=/opt/var/lib/rrd
RRDOUTPUT=/opt/share/www/rrd/
FORCEGRAPH=no

Script is of course executable, and i make the need dirs in the right paths and last, rrdtool is installed ^^.
Is of course lack of linux knowledge, but point please what i missing.
Firmware is .10 on a v1 500GP.

[cupacup]

Well you need to install bash first, then you should check grep functions(grep mnt, could also be grep part1, for hdd), also use latest version which have just been updated. Currently the hdd graph values must be updated every 30 s, but for the other(CPU;RAM..) values can be updated every minute using cron. Here is how my cron looks like:

*/1 * * * * admin bash /mnt/rrdstorm.sh update 0 1 3 4 5 
*/12 * * * * admin bash /mnt/rrdstorm.sh graph_cron s 0 1 3 4 5 
0 */1 * * * admin bash /mnt/rrdstorm.sh graph_cron h 0 1 3 4 5 
3 */6 * * * admin bash /mnt/rrdstorm.sh graph 0 1 3 4 5

Hi there.

Seems i encountered the same problem.

[xxx@xxx bin]$ ./rrdstorm.sh
-sh: ./rrdstorm.sh: not found
[xxx@xxx bin]$ bash
[xxx@xxx bin]$ ./rrdstorm.sh
bash: ./rrdstorm.sh: /bin/bash: bad interpreter: No such file or directory

Any idea what am I doing wrong ??

All I modified were the RRDDATA= and RRDOUTPUT= fields.

Thanks.

----------------------------

Later edit:

Ok, i was stupid, didn`t even read the error. Thing is that bash was installed under /opt/bin/bash and the rrdstorm script was looking for it under /bin/bash.

Replaced the header of file:

#!/bin/bash

with

#!/opt/bin/bash

and it seems to have executed successfully.
