Ive just got recommended cacti scripts - scgrab.
http://code.google.com/p/scgrab/

But I have problem to run it.

My installation:

1. I installed: cacti, python.

2. Download paramiko to your server: wget http://scgrab.googlecode.com/files/paramiko-1.7.6-AES-patched.zip and unzip.

3. Then I downloaded patched paramiko and installed it using this command:
python setup.py install (you have to be in folder where you extracted paramiko).

4. Then I downloaded scgrab: wget http://code.google.com/p/scgrab/downloads/detail?name=scgrab-2011-02-26.zip&can=2&q= and unzip it.

5. I copied it from downloaded place to /usr/share/cacti/site/scripts. It looks there like this: /usr/share/cacti/site/scripts/scgrab/scgrab.py

6. I set permissions for log and cache directory: sudo chmod -R a+rwx /usr/share/cacti/site/scripts/scgrab/log
sudo chmod -R a+rwx /usr/share/cacti/site/scripts/scgrab/cache

7. I generated keys on my server using this command: ssh-keygen -b 1024 -t dsa -C "monitor system" -f monitor
It created two files: monitor and monitor.pub.

8. I copied monitor to /scgrab/auth/keys

9. I uploaded monitor.pub to my ubnt device in ssh section(authorized keys). Also enabled ssh, port 22, enable password authentification.

10. I imported cacti templates from extracted scgrab folder. In cacti I created graph...

Problems: Graphs shows no data. In scgrab/log is this:
2012-04-16 10:40:04 - 2964: generate_cache: key file specified does not exist
2012-04-16 10:40:04 - 2964: main: data not available - exiting

What I have wrong, can anybody help? thanks

Zdravim,

vim ze se v readme scgrabu pise ze podporuje pouze fw 5.x presto bych se chtel zeptat, jestli je mozne to rozjet i na starych nanostationech v4.x?
