RRDTool Traffic Graph Tutorial - Extremely easy to follow !

[cupacup]

hello, the line

bash: ./rrdstorm.sh: /bin/bash: bad interpreter: No such file or directory

says it all. Bash should not be installed in /bin. Are you sure you installed bash via ipkg? Because bash is an optional package and is not installed by default. Also if you want to properly display disk data you should install coreutils. Check this tutorial.
Short said:

Get rrdstorm.sh from http://wl500ginfo.pastebin.com/f789cf38a and edit ./rrdstorm.sh for proper grep functions in disk section

RRDuVAL[5]='
SP=$(/opt/bin/coreutils-df "-B1")
echo -n $(echo "$SP"|grep opt|awk "{print \$3\":\"\$2}"):
echo -n $(echo "$SP"|grep mnt|awk "{print \$3\":\"\$2}")
echo
'

mnt should be changed to whatever you use for mount.
In shell

ipkg install coreutils
ipkg install bash
ipkg install cron
bash rrdstorm.sh create 0 1 3 4 5 6

Then edit crontab

vi /opt/ect/crontab

with these values

*/1 * * * * admin bash /path to/rrdstorm.sh update 0 1 3 4 5 6
*/22 * * * * admin bash /path to/rrdstorm.sh graph_cron s 0 1 3 4 5 6
0 */1 * * * admin bash /path to/rrdstorm.sh graph_cron h 0 1 3 4 5 6
3 */6 * * * admin bash /path to/rrdstorm.sh graph 0 1 3 4 5 6

and chmod it

chmod 0600 /opt/ect/crontab

and this is pretty much it. Good luck!

Also get the latest version from here and check the demo graphs.

[lordbone]

Yeah, i noticed the version change when you uploaded the new file. I got both the old and the new one. I also noticed that i was stupid with the bash thingie, and edited the post above. Gonna try now what u posted. Thanks.

[lordbone]

Ok, this is what i did:

Changed:

 
SP=$(/opt/bin/coreutils-df "-B1")
echo -n $(echo "$SP"|grep opt|awk "{print \$3\":\"\$2}"):
echo -n $(echo "$SP"|grep mnt|awk "{print \$3\":\"\$2}")
echo
'
RRDgUM[5]='space (bytes)'
RRDgLIST[5]="30 31 32 33 34 35"
RRDgDEF[5]=$(cat <<EOF
'DEF:optzasede=\$RRD:optzasede:AVERAGE'
'DEF:optprosto=\$RRD:optprosto:AVERAGE'
'DEF:mntzasede=\$RRD:mntzasede:AVERAGE'
'DEF:mntprosto=\$RRD:mntprosto:AVERAGE'
'CDEF:bo=mntzasede,UN,0,mntzasede,IF,0,GT,UNKN,INF,IF'
'AREA:bo#DDDDDD:'
'AREA:mntzasede#CC0033:/mnt:'
  'CDEF:root=mntzasede,mntprosto,+'
  'VDEF:sumr=root,LAST'

with

SP=$(df)
echo -n $(echo "$SP"|grep opt|awk "{print \$3\":\"\$2}"):
echo -n $(echo "$SP"|grep tmp|awk "{print \$3\":\"\$2}")
echo
'
RRDgUM[5]='space (bytes)'
RRDgLIST[5]="30 31 32 33 34 35"
RRDgDEF[5]=$(cat <<EOF
'DEF:optzasede=\$RRD:optzasede:AVERAGE'
'DEF:optprosto=\$RRD:optprosto:AVERAGE'
'DEF:mntzasede=\$RRD:mntzasede:AVERAGE'
'DEF:mntprosto=\$RRD:mntprosto:AVERAGE'
'CDEF:bo=mntzasede,UN,0,mntzasede,IF,0,GT,UNKN,INF,IF'
'AREA:bo#DDDDDD:'
'AREA:mntzasede#CC0033:/tmp/mnt/disc0_3:'
  'CDEF:root=mntzasede,mntprosto,+'
  'VDEF:sumr=root,LAST'

I don`t know if that is good. I have like, 1 partition mounted to /opt and the other to /tmp/mnt/disc0_3 since I head oleg`s firmware doesn`t mount it anywhere else.

Don`t know how correct that edit is.

And another thing, the script seems to run successfully, but it doesn`t generate any output. The RRDDATA and RRDOUTPUT folders are empty after script execution.

I think it crashes silently or something.

I am already running rrdtools for traffic if it makes a difference.

-- BTW, awesome demo.

[cupacup]

This is how it should look like.

SP=$(/opt/bin/coreutils-df "-B1")
echo -n $(echo "$SP"|grep opt|awk "{print \$3\":\"\$2}"):
echo -n $(echo "$SP"|grep disc0_3|awk "{print \$3\":\"\$2}")
echo
'
RRDgUM[5]='space (bytes)'
RRDgLIST[5]="30 31 32 33 34 35"
RRDgDEF[5]=$(cat <<EOF
'DEF:optzasede=\$RRD:optzasede:AVERAGE'
'DEF:optprosto=\$RRD:optprosto:AVERAGE'
'DEF:mntzasede=\$RRD:mntzasede:AVERAGE'
'DEF:mntprosto=\$RRD:mntprosto:AVERAGE'
'CDEF:bo=mntzasede,UN,0,mntzasede,IF,0,GT,UNKN,INF,IF'
'AREA:bo#DDDDDD:'
'AREA:mntzasede#CC0033:disc0_3:'
  'CDEF:root=mntzasede,mntprosto,+'
  'VDEF:sumr=root,LAST'

You can check if rrd database is beeing updated with rrd with this:

[admin@dz0ny root]$ rrdtool lastupdate /path to/hdd.rrd 
 optprosto optzasede mntprosto mntzasede

1217337065: 264934400 226105344 73048051712 79097274368

[lordbone]

Thanks for the quick answer. I re-downloaded the file, and made the following modifications

#!/opt/bin/bash

instead of

#!/bin/bash

the modification u pasted now, with disc0_3, and

 
RRDTOOL=/opt/bin/rrdtool
RRDUPDATE=/opt/bin/rrdupdate
RRDDATA=/opt/var/lib/rrd
RRDOUTPUT=/opt/wwwroot/rrd/hdd
FORCEGRAPH=no

to reflect the settings i`m using.

This is what it shows when i run it

[xxx@xxx bin]$ ./rrdstorm.sh
[xxx@xxx bin]$ ls /opt/var/lib/rrd/
total 188
drwxr-xr-x 2 xxx root  4096 Jul 29 13:09 .

total 8
drwxr-xr-x 2 tbone root 4096 Jul 29 15:11 .
drwxr-xr-x 3 tbone root 4096 Jul 29 16:15 ..

It runs with no visible errors, but it kinda` doesn`t do anything.

Any idea ?

[cupacup]

Hello, yes because it should not. try

.rrdstorm.sh create 0 1 3 4 5 6

this one is for initial creating of databases an htmlfiles

.rrdstorm.sh update 0 1 3 4 5 6

this one is for updating values

.rrdstorm.sh graph 0 1 3 4 5 6

this one is for generating graphs

.rrdstorm.sh graph_cron s 0 1 3 4 5 6

and this one is for quick updates

I hope it works for you.

[lordbone]

Yup, worked. Nifty looking graphs

Thanks for everything mate.

[cupacup]

Thanks for everything mate.

No problems, I am glad you like it.

[poiu]

Still no run here.
When i execute i get :

./rrdstorm.sh : line 594 : syntax error near unexpected token `) '
./rrdstorm.sh : line 594 : ` help)'

Between ` and help in line 2 is some spaces, but forum deleted them.
In cron modifications is done and modifications of script is the disk0_3 on right section and right paths for files.
Maybe my copy/paste skills is outdated
Try with different editors and browsers on win/router but same result.
Lordbone you can upload the file here ?

[lordbone]

Yup, here u go mate:

You can get it from here

Good luck with it

[poiu]

Thank you lordbone, your file work ok, maybe the script get tainted on source ...
Still prezentation is bad, need enter by hand cpu/hdd/ etc, the index is build empty, overall graphics is nice

Well my copy>paste skills were bad not yours, sorry for that!

[poiu]

No harm done, copacup, we all tanks you for sharing your work with us ^^ .
But a beauty will be if the graphics are build in main page, not spread.
This is html work i think, but not any skills here, again..
Overall charge on processor power is around 20% so i will live with, hope the Asus will too,, the another scripts find it around charge like 50% so was innaceptable, so i will let your script work.
Another thing, wlan is blank, because of interface diferences between v1 and v2 ?
And to kill cpu temp because wont work anyway what is needit ?

LE: Y want to kill memory alocation/load/cpu temp to save power, i wont need it, is a quick way to do it besides try to comment some portions of script ?
The 1,2,3,4,5,6, way will do ?

[cupacup]

Yes you could do it or simply delete all html files and issue command

rrdstorm.sh create 4 5 6

. Little explanation 0 is LOAD, 1 is MEMORY, 2 nothing yet, 3 CPU, WAN 4, DISK 5 and 6 WLAN.
So if you want to create, for example just stats for disk, you would issue command rrdstorm create 5, values would get updated by rrdstorm update 5 and so on.
LE: If you want just some graphs on main page, you can edit index html. And place those images there.
