Trouble with RRDTool and updated uClibc

**yeager** · 03-10-2005, 10:48

I don´t need graph generated by rrdtool, i need only a simple webpage whit this:

................Today.......This week.......This month
wlan...........64MB...........564MB............2354MB
pc1............47MB...........345MB............1005MB
pc2............09MB...........123MB............0547MB
pc3............08MB...........096MB............0802MB

Modify the package on your own ?
Seems no one else is interrested in this at the moment.
For my own, i would like to see something like text stats inbuild to the web interface, but at the moment, no interrest to do it

Hi,
I had some problems with rrdtool and updated uClibc. So what i am done.
1. Prepared my harddrive for extended packages.
2. Update ipkg as said on http://www.nslu2-linux.org/wiki/FAQ/Optware-uClibcBuild
3. Using tutorial on http://wl500g.info/showpost.php?p=18494&postcount=1 install rrdtool
All step done without errors. But when rrtool.sh script try create rrd data file it`s freezed down. I figure out that rrdtool.sh stopped on `rrdtool create "${1}" etc.`.

Anyone can help me with it or recommend some alternative programms for statistics collection?

**oleo** · 20-12-2006, 12:21

rrdtool is the only one giving me a trouble. I am looking for a ways to resolve this issue, but it looks like that isnan() function is constantly called in a loop.

I supose there is a bug in rrdtools or some building info or maybe uclibc problem.

I have native compiled libpng, libart_lgpl, freetype, zlib and rrdtool but produced the same resulting lock up.

Strangely
rrdtool create load.rrd DS:sysload:GAUGE:600:U:U RRA:AVERAGE:0.5:1:48
works, while
rrdtool create loadavg.rrd --step 60 DS:load1:GAUGE:120:0:U \
DS:load5:GAUGE:120:0:U DS:load15:GAUGE:120:0:U RRA:AVERAGE:0.5:1:2160
locks up

**_Denis_** · 20-12-2006, 13:06

oleo, thanks for reply.

But when call rrdtool with different params, it create a file.

For example.

rrdtool create temperature.rrd --step 300 \
DS:temp:GAUGE:600:-273:5000 \
RRA:AVERAGE:0.5:1:1200 \
RRA:MIN:0.5:12:2400 \
RRA:MAX:0.5:12:2400 \
RRA:AVERAGE:0.5:12:2400

Do you know some similar packages for collect statistic data?

**oleo** · 20-12-2006, 13:08

Could you possibly find isolated example that fails. Currently I am creating debug version of rrdtools natively to be debuged on router. And I need minimal example.

**_Denis_** · 20-12-2006, 13:19

What do you mean by isolated example?

Work
rrdtool create test.rrd \
DS:in

ERIVE:600:U:U \
RRA:AVERAGE:0.5:1:600

not work
rrdtool create test1.rrd \
DS:in

ERIVE:600:0:125000000 \
RRA:AVERAGE:0.5:1:600

May be some problems in min max value?

ps
it doesnt like MIN = 0

**wirespot** · 31-01-2007, 08:14

Can anyone point me to a rrdtool 1.0.50 ipk file, the one that doesn't freeze when rendering certain graphics? All the repositories I've seen seem to include only recent versions.

**oleo** · 31-01-2007, 09:28

Install http://wl500g.dyndns.org/7g/ and then try again

**wirespot** · 31-01-2007, 17:38

Ah, that's better. See here:

Hi!

My problem is that the log file is empty and the directories "RRD" under: "/opt/share/www" and "/opt/var/lib/" aren't created. I therefore cannot monitor

I've installed RRDTool via ipkg and that works. I have followed macsats cronguide and tested with the 5 minutes test script in the same guide.
That test script works as well (i have it placed in /opt/etc/cron.5mins/).

I was unable to use the default dir "/opt/usr/bin" since it didn't exist. I've tried although by creating that dir and placing the script there but that didn't help.
I've also tried changing the default dir to "/opt/bin" in the script and also placing the script in there. No luck there I'm afraid.

I have the "rrdrun.sh" script inside /opt/etc/cron.5mins/ and I it's executable.

I'm using lighttpd and perhaps that affects everything?
Since I'm unable to copy text from Putty I have included a printscreen of my currently running processes.

I hope someone might know what this is. Would love to get this working please!

Hi,
I can only help you with your putty problem...

Select what you want to copy and press Ctrl+Insert. And then paste it in putty with "Shift+Insert", or Ctrl+V in Windows.
Or use, for example:
ps axf > /opt/ps.txt

**tzd99** · 04-07-2008, 23:55

I can paste into putty but not the other way around (copy from putty). Tried via ctrl+insert but taht didn't help I'm afraid. Thanks for your reply though

UPDATE: just found out there's some issues with the linux version. Also found out i could use Konsole instead..... now that was a lot easier than puTTY

Help pls...

**FastCat** · 07-09-2008, 21:25

The problem has started to dare gradually.
To begin with, what a script (my first message) though see as that has started to work on wl-700g. Its first line should be changed to the

Code:

#!/opt/bin/sh

Once again we try to start a script.

Code:

[root@WL700gE bin]$ ./rrdtool.sh
Sun Sep  7 19:27:01 UTC 2008
RRD Database dir: /opt/share/www/lighttpd/rrd/ does not exist...Creating Now....
 index.html does not exist.....Creating Now....
Create started...
 week.html does not exist.....Creating Now....
Create started...
 month.html does not exist.....Creating Now....
Create started...
 year.html does not exist.....Creating Now....
Create started...
WAN Interface: eth0
LAN Interface: vlan0
WLAN Interface: eth1
RRD file : /opt/share/www/lighttpd/rrd/eth0.rrd does not exist...Creating Now...

Directory rrd it has created and.html files too has created. And here.rrd and pictures he does not wish to create files. A script it is necessary to "hang" (while it violently not to interrupt) with the message which "fat" is allocated (in broad gulls rrdtool anything is not present).

That is interesting. A kind command:

Code:

rrdtool create load.rrd DS:sysload:GAUGE:600:U:U RRA:AVERAGE:0.5:1:48

it is carried out perfectly. rrd the file is created.

From here it is possible to draw a conclusion that with program adjustment of mine wl-700g all is good. And a problem in the script.

Help pls to adapt the given script under wl-700g
