Cacti

Hi all,
thinking out loud here due to the annoyance of pachube/cosm rebranding issues.
I would like to have access to charts or varying time scales via mobile devices, this has apparently been removed from xively as far as I can tell.
from the bit of googling I have done today I was wondering if anyone has any thoughts or ideas on the following? I can't see why this isn't possible.
obtain a raspberry pi and install Cacti. See http://n00blab.com/cacti-pi/
txfer the data to cacti as Brett describes in the cacti section of the wiki.
Publish the required charts as a webpage as described here: http://forums.cacti.net/viewtopic.php?f=21&t=42714
I would appreciate people's thoughts on this before I spend my dollar!
cheers
Garry

Garry good job. I must move
Garry good job. I must move my cacti installation to another box (VM) and get it setup again. Good thing I wrote some nice notes as I would have forgotten half of those steps involved by now.

Gary, I think we can do
Gary,
I think we can do better. You didn't handle the case where state=? which is the startup value when we don't know if its on or off yet. I'm defaulting this to 0 too in my logic in yours you returned the ? value (what does this mean?)
I'm getting rid of the popen() at the same time I never did like that bit of hackiness.

I updated the code in the wiki.

help..
Brett?
Cacti was working fine until I tried to enter the updated xapquery.py from the wiki.
Now I am getting this error when I check that it is working:
------------------------------------------------------------------------------
Traceback (most recent call last):
File "./xapquery.py", line 24, in <module>

-----------------------------------------------------------------------------------------------
I haven't rebooted the pi 'cos Cacti still seems to be working, but I didn't take a copy of the original
program so can't return to working program (except state of course).
I have tried a few things but am clearly lost.
Any help much appreciated.

Its not a cacti python scripting bug.
Kim, That python code for CACTI is correct. The bug is in your xapCacheWebserverApplet.lua file. You are running on old version You should be running something based on version 1.5
File "/usr/lib/python2.7/httplib.py", line 397, in _read_status
raise BadStatusLine(line)
httplib.BadStatusLine: HTTP/1.0 200/OK
Now see change: http://code.google.com/p/livebox-hah/source/detail?spec=svn445&r=423
The latest is in /etc_ro_fs/plugboard/samples
You can either
- copy over the new applet and modify the VFS section again
- or make the same code change in your local copy.

What a brilliant idea
Looks like i know where my spare node is going literally in the bin :)
Garry quite right integration to CACTI was something that I prototyped up quite some time ago.

I have a PI but I could never get its ethernet port to work I think its broken and I was burning too much time screwing around with it so I stopped and now its just sitting on my desk as a constant reminder of something I wanted to play with.
