Cisco CBWFQ monitoring

[pwozney]

I use QoS on some WAN connections and I am currently using cacti to monitor the bandwidth consumed by each class.

I've posted this in another thread that is in the Feature Request forum, but since it's working now I figured this is a good place to start a new discussion.

The system is based on a perl script written by Andy Brauer back in 2002. I have completely rewritten the script to report in cacti standard formatting. The perl script was written on linux, and requires snmpwalk. If you run this on another operating system, or with a different version of snmp you may have to tweak it.



I'll try to help you as I can, but feel free to modify the script to your own purposes.

The last xml file.

Whoops forgot one.

Whoops forgot one.

I already import all the script and copy cbwfq.xml to <path_cacti>/resource/script_queries/cbwfq.xml, but it's still come an error in Console -> Data Queries -> (Edit) -> Associated Graph Templates

Warning: Variable passed to each() is not an array or object in /var/www/localhost/htdocs/cacti/data_queries.php on line 312

Could you please give me a hand.

Where did you get the cbwfq.xml file from? Did you rename the perl file? If so, I think that one should be a seperate file and be referenced to from the cbwfq.xml file.

On a sidenote, I haven't managed to get it to work either. I would appreciate it if the topicstarter could post all the files he currently uses in a zip file or something.
Sorry to be such a hassle

[budhal2003]

Yes Leon, apparently I did rename the perl file to be used as xml
So there should be 2 different files of pl and xml, does anybody know where can I get this particular xml file? thx a lot

[nonolk]

Did someone manage to make it working ??
I think we have to make your own cbwfq.xml, but I don't know how, and maybe I'm wrong. So if someone could help us, I would be nice.

Thank's In advance.

Ahh feh. I forgot to post cbwfq.xml - quite possibly the part I had the most trouble with myself. In my defense the cacti front end does not include this critical xml file in it's export function, and that's why I forgot it.

Here are the files in a zip file, as requested.

The perl script goes here:
cacti/scripts/cbwfq.pl

I created a symbolic link - I've added that in the zip as well but I'm sure you can do that yourselves, or just rename the cbwfq.0.53.pl to cbwfq.pl.

The script xml file goes here:
cacti/resource/script_queries/cbwfq.xml

Everything else you can import into cacti through the frontend. Thanks for spotting this Leon!

hi

the imports work wonderful, but what about the .pl script. I'm new to cacti so i would assume it needs to create a data input method ? If its supposed to am i to create it myself ?

thanks

[pwozney]

You're right, you do need a data input method. It's not exportable by cacti, so I've saved a screenshot of mine.

The input string is hidden on the screenshot - so use this:

<path_cacti>/scripts/cbwfq.pl <ip> <community> get <class>

[nonolk]

Hi,

I have a little problem to mkae this working, now for cacti everything seems to fine, exept that data collected by the cbxfq.pl.
What I don't understand is with your old script I get 4 classes with bytes. But with the newer one I have nothing.
Could you help me please ??

Any help will be greatly appreciated.

pwozney - Thanks alot. I managed to get it working thanks to your help.
I had to change some variables and calling options in the .pl file because of the version of netsnmp I am using (win32 ) but that was done without problems.
In combination with Weathermap this really is a great addition. Thumbs up for you.

nonol - did you change the filterstrings in the .pl file? Otherwise please tell us what setup you are using.

[nonolk]

I'm using debian testing (sarge) with stock kernel. My version of snmp utils is 5.1.2. I don't change the filter because I don't know what to change, the filter says "QoS" and it's what I want to monitor.

Thank's for your help

Update : I change the filter to ".*" and now I can get my 4 Qos class, so I can create graph, but there is still a problem, I can't get any values, so the graph are empty. I'm sorry I'm a little bit tirred.


And here is the debug output from cmd.php
