Cisco CBWFQ - PHP Script Server

[maxstoner]

Hello,

We used the original Cisco CBWFQ Scipts from this topic:
http://forums.cacti.net/viewtopic.php?t=7401

But we had some performance impacts when using this script on our servers. For my opinion this is because of using script/command and the script itself is doing 4 snmpwalks whenever requesting a "get".

Now I did some modifications to the original script of user pwozney.

First of all I changed language to PHP. Then in the second step we are using PHP script server, so we do not need to recompile the script each time.

The last step was to eliminate the 4 snmpwalks when doing a "get". We only need one snmp_get when fetching the values now.

I will post all necessary parts here soon.

Import cacti_graph_template_cisco_-_cbwfq_statistics.xml and cacti_data_query_cisco_-_cbwfq_statistics.xml to cacti. It is exported in version 0.8.7b.
Copy cisco.cbwfq.xml to <cacti>/resource/script_server/
and ss_cisco_cbwfq.php to <cacti>/scripts/

Shouldn't there also be a data input method to go with this??

[maxstoner]

sorry, can't test the export. Included date_query_export now. Hope that's all.

[drewshin99]

thanks for sharing this maxstoner, this is the only script for cbwfq that has worked for me!

This script works perfectly on the 6509.
Thank you very much.

I just get this error when I import the templates, using versio 0.8.7

Error: XML: Hash version does not exist.

Hi maxstoner,
I have script polling on 6509E with dual sup720 and DFC cards. The graphs are reporting less than actual traffic. Is there the way I can combine all traffic through all the slots.
Thanks,
Snoopy

I know a manual way of doing it. Gotto graph management - click add - leave graph template and host as none and click create. Then under graph items add your data sources you want to graph. This will combine all the datasources into 1 graph. You can add gprint and all sorts as you would when creating a new graph template.

Hi

Does anyone know of what OID I can use to get the bandwith from each class map / policy?? I want to be able to create an Hrule based on that so I can set a threshold for my graphs to see if traffic is bursting above my COS queues.
Is this possible when they our providor are using bandwith remaing statements rather than a bandwith statement with a bps figure?

Cheers

Hi

The template and script was initially working fine. I had 2 devices working ok using this script. I have tried to now add additional devices but its not working for any new devices I tried to add the template too.

WHen I do a debug on the script I get this:-

+ Running data query [34].
+ Found type = '6 '[script query].
+ Found data query XML file at 'C:/Apache2/htdocs/cacti/resource/script_server/cisco_cbwfq.xml'
+ XML file parsed ok.

etc, etc, etc etc,

Here is a successful run on annother device

These are both Cisco routers on our ISP managed WAN.

I'm able to poll the MIB in question as shown below so I know its allowing SNMP to this MIB.


C:\net-snmp\bin>snmpwalk -v2c -c public 32.34.94.221 .1.3.6.1.4.1.9.9.

I have also tried walking the whole MIB as shown

When I run the script from the CLI I get a warning error. I get this when I run it against a device that works and one that doesn't, which doesn't make any sense!

Has anyone got any ideas??

Just to add to this. I have just tried testing the script server using the host disk, which works fine, and I also get the same warning message. So maybe this is default behaviour when using the script server???

Hi

I have also just double checked I can walk all the OIDS that are used in the script.

I have started trying to add all of our ISP routers to this template and at the moment only 2 are working correctly. Its really strange. As a test I removed the template from a working device and re-added it and it still scanned the device and bought back results. This proves that the script/template hasn't been messed with since I initially added the working devices.

If anyone has any ideas it would be appreciated.

Cheers

Jay

Does this script graph CBWFQ Input, or just bits OUTPUT? Does anyone know of a way to graph CBWFQ bits INPUT? Thanks.

[nxumdon]

Can anyone assist with the creation of the data input method for this? Thanks...
