View Full Version : RRDTool Traffic Graph Tutorial - Extremely easy to follow !
ASUS WL-Series RRDTool Tutorial
The guide is made using a ASUS WL-500G Deluxe (or WL-500GX as it is sometimes called).
It should however apply to all the ASUS wireless line of products that are Linux based. Theese products are to my knowledge :
# ASUS WL-500b
# ASUS WL-500bv2
# ASUS WL-500g
# ASUS WL-500g Deluxe (WL500-gx)
# ASUS WL-HDD
If you are the lucky owner of any of the above devices, you have come to the right place.
If you still dont have one of the above devices - dont hesitate, go buy one :-)
After following the steps in this tutorial, your ASUS WL device will have all its normal functionality, and also make Graphs of the Traffic Usage using RRDTool.
Tutorial Index
1. Prerequisites - What is needed to get started.
2. Installing and Configuring RRDTool
Prerequisites
All you need is :
# One of the above Asus Wireless devices
# An USB Harddrive or USB Memory Stick / Keyring with some 50-100 MB space.(For the WL-HDD you just need a regular Harddrive)
# Firmware version 1.9.2.7-4 (or higher) by Oleg
In order to be able to follow this tutorial to the last detail, you have to have a setup I created in the ipkg Tutorial (http://www.macsat.com/ipkg.php)
Also for beeing able to actuately see the graphs created, one option would be to follow my PHP Enabled web server Tutorial (http://www.macsat.com/php_web.php)
Finally you need to have cron running to get the traffic databases updated, check my cron tutorial. (http://www.macsat.com/cron.php)
Installing and Configuring RRDTool
As usual Olegs excellent firmware, and its support for the ipkg package system, makes installing software as easy as:
ipkg install rrdtool
Once the software is installed all that is really needed for getting rrdtool running, is a small script that I wrote.
You can download the script here (http://www.macsat.com/rrdtool.sh)
Copy the rrdtool.sh script to /opt/usr/bin
Now - to make rrdtool start collecting data and making graphs you need to place a small script in /opt/etc/cron.5mins/
The script could be called rrdrun.sh and should contain something like:
#!/bin/sh
/opt/usr/bin/rrdtool.sh >> /opt/var/log/rrdtool.log
Remember to make the script executable :
chmod +x rrdrun.sh
If you have followed my Crontab Tutorial this will make the rrdrool.sh script run every 5 minutes 0, 5, 10, 15... and so on minutes every hour.
It will also create a logfile in /opt/var/log containing information on the data sent to the rrd database.
The script will place the rrd databases in /opt/var/lib/rrd/ and the images and html pages for presentation in /opt/share/www/rrd/
Theese locations can be customized at the top of the rrdtool.sh script.
Every 5 minuts traffic information will be written in databases for the WAN, LAN and WLAN (Wireless) interfaces. Every 30 mins, at 00 and 30 every hour, the images with the graphs will be created.
I have chosen only to create the images every 30 minutes, since it is rather CPU intensive to create thoose images.
Once the script has been running past either XX:00 or XX:30, XX beeing the hour when you first create the /opt/etc/cron.5mins/ script, you can direct your browser to : http://yourrouterip/rrd/ and see nice graphs :-)
My script will create graps for 1 day, 1 weeek, 1 month and 1 year scopes.
For additional information and updates, check out www.macsat.com !!

The rrdtool.sh script is updated.....tutorial should still be up2date (except for some bits and pieces of information).
Check www.macsat.com....not needed though.
Maybe I have stupid question, but where could I find rrdtool suitable for Asus? Or it is already installed in Oleg's FW and the command ipkq install rrdtool will only activate it?
What about reading the tutorial ?
It is stated quite clearly how to install it :
Installing and Configuring RRDTool
As usual Olegs excellent firmware, and its support for the ipkg package system, makes installing software as easy as:
Code:
ipkg install rrdtool
I read the tutorial. And what about unistalling rrdtool? Only command ipkq uninstall rrdtool? :) .
Remove with :
ipkg remove rrdtool
Nice going macsat! Haven't had time to test it yet, but what you need for you tutorial is some screenshots! I would love to see how it looks..

Hi
There is a few updates:
# The new graphs are bigger
# Added Min, Max, Average, Current
# During the image generation the graph are not accessibles so new images are created with a extention .new and renamed when done.
Also some pics.
Note that theese are the WAN pics, the script creates for WAN, LAN and WLAN separately, and also creates simple webpages that includes them.
The script is not that old, and hence there is not so much history included in the graphs :-)
Just got this up and running and i like it a lot...
thanks a million for sharing....tis very good.
Toil
I think it would be a nice feauture to generate graphs to show how much bandwith each LAN user is using i.e. each MAC-address in the routing table.
Even plotting how many LAN users and when a specific LAN user is connected would be a nice feauture..
Keep up the good work!
All theese features takes something completely different though.
This would mean using iptables for generating the rrd data - this is not how it is done in my version.

what do I have to do, to get the daily graph updated every 5 minutes and aditional an "hourly" graph, updatet every minute?
I'm a noob to Linux, so im proud that I get this runing....but I realy would like to have the "features" mentioned above...
Thx, Astro
It can all be done in the rrdtool.sh of this page: http://www.macsat.com/rrdtool.php
Find this in the code:
# Update Daily graphs every 10 mins
if [ "${MTIME}" = 00 ] || [ "${MTIME}" = 10 ] || [ "${MTIME}" = 20 ] || [ "${MTIME}" = 30 ] || [ "${MTIME}" = 40 ] || [ "${MTIME}" = 50 ];
then
# 1 Day Graph
echo "Daily Graphs created....."
CreateGraph "${RRDIMG}/wanday.png" 86400 "${WANRRD}" WAN
CreateGraph "${RRDIMG}/landay.png" 86400 "${LANRRD}" LAN
CreateGraph "${RRDIMG}/wlanday.png" 86400 "${WLANRRD}" WLAN
fi
Just above this, you could insert something like:
# Update hourly graphs every time cron runs the script
# 1 Hour Graph
echo "Daily Graphs created....."
CreateGraph "${RRDIMG}/wanhour.png" 3600 "${WANRRD}" WAN
CreateGraph "${RRDIMG}/lanhour.png" 3600 "${LANRRD}" LAN
CreateGraph "${RRDIMG}/wlanhour.png" 3600 "${WLANRRD}" WLAN
This will create an hourly graph for each interface every time the cron job runs the script...that would be every 5 mins in the current setup.
I honestly doubt it would be a good idea at all to do this due to the low ressources of the Asus router, but you will probably find out ;-)

i've now done this:
The script runs ervery minute, (since I can't set cron jobs every xx-secounds :-( )
So I get a value every minute...
To make my "hourly" graph I take two "points", so i get a new value in the graph, every 2 minutes.
But I changed the time, the graphs are generated.
Hourly: every 7minutes
daily: every 11minutes
and I made the graphs a bit smaller, witch saves a lot of CPU time...
works great :-)
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.

I can't connect to my router with Putty. Putty says: Network error. Connection refused.
((I use win xp)) Please help:(
Hi, try to follow this easy tutorial here:
http://www.macsat.com/macsat/content/view/12/29/
to activate "Dropbear" on your Asus Router then you should be able to connect to your router over SSH which is more secure than telnet btw.
regards,
schim

Yes this limit is in php version. I have changed thttpd without php to 300 seconds. So this is a way to go.

Did you recompile thttpd? Or is it standard in thttpd without php?
I tried to compile thttpd with php but the php-patches for thttpd are for an outdated version only.
Hi...
I've a little problem...
Everything works fine apart from one little thing:
How do I Copy the rrdtool.sh script to /opt/usr/bin?
Hi...
I've a little problem...
Everything works fine apart from one little thing:
How do I Copy the rrdtool.sh script to /opt/usr/bin?
One uses the copy (cp) command :) . Go to the directory where the file is located now and then type the following:
cp rrdtool.sh /opt/usr/bin
and when needed:
chmod +x /opt/usr/bin/rrdtool.sh
to make the file executable
<----- Linux n00b, but this is something even I know :D
Has it any use of setting the run rrdtool.sh more often than every 5 mins? I've set it to 2 mins, but I can't see for sure that the graph has more detail then 5 mins.
Anyone who knows?

Anyone who knows?
The only thing I can think of is that the graph will show more accurate speeds. So unless your speed varies a lot during 2 intervals, you won't get much more accurate graphs.
I stick with the 5 min. interval as it is stressing the router as it is already :p
Tries both of them now. And indeed it doesn't matter much. Graphs are a little bit more detailed but not enough to stress the router more then 100% extra (I used to check it every 2 minutes).
Ps, I installed in on my WL500G Premium. Just little path changes (like /opt/bin instead of /opt/usr/bin). And make sure if you also follow the Cron manual of Mascat that the USER who runs the run-parts file is admin and not root (!!) in the crontab file (in /opt/etc/). Took me ages to find that out

Hello,
Thanks for all the tuts so far. All of them were clear but with this one i encounter some problems.
I did Wget http://www.macsat.com/rrdtool.sh while i was in the /tmp directory. But when i want to copy it to /opt/usr/bin i got unable to open `/opt/usr/bin': No such file or directory
I can also not cd directly to /opt/usr/bin but i am able to cd one directory at a time....
I have an usb stick of 512 Mb mounted on /opt. as stated in another tutorial.
So i am actually kind of stuck here. Can anyone help me out?
Go to the /opt/usr/bin directory and use the Wget http://www.macsat.com/rrdtool.sh command there. It should download it there.

Thanks for your reply, but now the response is

-sh: Wget: not found
And when i leave out http:// the response is :
@(none) /tmp]$ wget www.mascat.com/rrdtool.sh
wget: not an http or ftp url: www.mascat.com/rrdtool.sh
I just don't get it in /opt/usr/bin....:confused:
You forgot the http://. This one works, tried in my own config to make sure. Just run it in the designated folder
wget http://www.macsat.com/rrdtool.sh

16-10-2006, 20:15
Thanks for the advise, but that doesn't work because it is a read only filesystem...
here is the response:
get http://www.macsat.com/rrdtool.sh
wget: rrdtool.sh: Read-only file system
But everyone who followed this tutorial should must have had this problem :rolleyes:
Maybe macsat himself can give me the golden tip...???

To which directory are you trying to write the file, as in: from where are you calling this command? The response suggests that your are trying to download the file to a read-only part.
Did you try moving to /opt/usr/bin before calling the
wget http://www.macsat.com/rrdtool.sh
command ?
did you remember to mount a disk on /opt ?
To me it looks like you are trying to write directly to the flash, which isnt supported in Olegs firmware (that part of the flash anyway).

What to check to make it work?
My problem still is the same. THHTPD seems to shutdown on its own :mad: Where is the logfile ? Has anyone else suffered from this fenomenon?
I began from scratch, installed SSH, VSFTPD, THTTPD but still the problem stays :(

I have one more question though. Why is my WAN graph always at a steady 222 bytes...:confused:
It doesn't matter if download a lot or not....it's always 220 bytes...strange. Also i tested the LAN & WLAN graph bij transferring a big file from my pc (wired) to my laptop (wireless).
The LAN graph shows a big peak for INCOMING traffic and the WLAN graph shows a big peak for OUTGOING traffic... I think it should be the other way around... do i interpret it incorrectly?
Thanks in advance
nice tutorial. working perfectly. thanks!

Thanks for the tutorial, works fine.
Only problem I had was with the graph creation, since I currently don't have a wireless client the data is 0 and this apparently caused the generation to hang.

Is it possible to add another graph which shows the load of the router?

I think that I've installed, because I can load the page, but It didn't show any graph, Will I need to w8 a day to see it? or is the admin root problem? I'm running wl500gP, if that's the problem How do I solve it?
I've admin in crontab...
solved with chmod +x rrdtool
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
EDIT:
imo txt stat version would be nice

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:\

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/optware/oleg/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.

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
