Cisco CBWFQ monitoring

[starkie]

Thanks

I can upload other scripts just not this one.

It works fine on my redhat install just not on win2k

Any idea's

[starkie]

Hi,

Can someone who has this working on win32 please export the templates and post them.

It appears as if they will not import either by file or by text.

I can import them on my redhat install

Thanks in advance

Hi, I'm using one policy-map containing serveral classes (8) and apply it to ~30 dot1q VLAN subinterfaces.

This looks great in IOS where I can get individual info for every subinterface with:
"#show policy-map interface gigabitEthernet 0/1.100" for instance.

It seems to me like the cbwfq.pl script is not interface oriented but class oriented. It starts with checking what classes we have and then reading (I guess) only the first appearance of that classes values.

The thing is that the MIB has statistics for each subinterface even though it's the same policy map and classes.

Does anybody know a way to get per-subinterface CBWFQ statistics when using the same policy and classes?

I have just got the CBWFQ monitoring resolved and I know what you mean however this is not as starightforward as it may seem. Firstly you would need to run the following command on the cisco platforms to stop the ifindex in snmp changing.

snmp-server ifindex persist

Next problem is you need to map the queues per interface which is no mean feat. The attached link explains how this is done -

http://lists.ee.ethz.ch/mrtg/msg24544.html

I have been trying to find a nice solution to the same problem but get to the same point as you have. I have to map many interfaces with 4 queues on a 7600 which I can do manually but not automatically. I don't do the code thing so I can't work out the way to compile the xml or perl scripts but I am not too bad on Cisco or SNMP so I have access to some Cisco kit and would not object to any testing.

We have managed to create some dirty code that does the work we thought we needed. It uses SNMP.pm "-- Perl 5 interface to the net-snmp toolkit" ver 5.2.1 which gives it some speed compared to the scripts using external snmpwalk.

Would really apprecieate if somebody with a sense for coding had a peek and made it look good.

The script works with a router that has one policy on multiple interfaces, it does currently not handle a router with multiple policies.

Our current problem is the integration with cacti.

We have a working data query that lists sub interfaces that has QoS configured and the interfaces' alias (Cisco descr).

We have a data input method that uses the attached script with <IP> <comm> <QoS internal int index from data query>. The problem is that the QoS internal int index from data query is not passed on to the data input method script.

Have we misunderstood something basic in cacti thinking?

Hi, good template...

Can you help me to translate this Template to run on windows ?

I believe thae I need to change cbwfq.pl, because there is error when I run the command inmode DOS (this is a test)

C:\>perl c:\cacti\scripts\cbwfq.pl 192.168.1.1 mctyunt query class
No community name specified.
USAGE: snmpwalk [OPTIONS] AGENT [OID]
Version: 5.2.1

Thanks a lot

Guys,

I solved my problem.

Look:

OLD => = `$snmppath -v $version -c $node $comm $ilist_oid`

NEW => = `$snmppath -v $version -c $comm $node $ilist_oid`

You need to change "$node".

Thanks

Please,

I did the graphs with QoS Class OK
Now I need help to use the other files:

I used:
Import : cacti_data_query_cisco_get_cbwfq_classes
/cacti/resource/script_queries/cbwfq.xml
/cacti/scripts/cbwfq.pl

And the files:

cacti_data_template_cbwfq_throughput.xml
cacti_graph_template_cisco_bits_output_from_qos_class.xml
cacti_host_template_cisco_router.xml

With this template, will I do only graphs about the "Class" ?
Please can anybody explain ?

Thanks

This is another script based on the original one

the changes are

1. it can monitor class with the same name on diferent interfaces
2. I remove the filterstring because I dont need it.
3. It run much faster when it get the output because it only snmpget one value not snmpwalk few times.
4. it can also monitor drop rate of the class-map just add new graph template and change your xml.

It need more developmant if we want it will look better but it work for me.

The current data query should work with this script but backup you your DB before you change the script because it come without any warranty

Thanks

Thanks

Is there manual about this file ?

[moonman]

I will try to export template later today
but you can use the current one if you dont need the drops
just copy the script to your script dir and rename it to the name of the original script

Thanks

[moonman]

Here is beter looking script now with XML and data query template

To install

1. put the cbwfq.pl in your cacti scripts directory
2. cbwfq.xml in resource/script_queries/
3. import the data query template to your cacti

I seem to having a strange issue and wanted to find out if others were as well. I have tried pwozney's templates and script and am able to get some graphs. I try moonman's since I would like to see some per interface graphs and I get no graphs. In fact it doesnt even create any RRD's when using moonman's templates and scripts.

[moonman]

can you send some screen shot from your cacti please

Thanks

[sohailb]

Im not sure which screens you want me to share. Here is what I have done... I imported the template, copied the script and xml file into the right locations, and set up the data input method. When I add this data query to a host, it does show me the names of the classes and from which interface they belong. When I try to graph them, rather than showing the previously shown name, it now shows |query_class| instead. At this point, I let it run for a while to get some data and when I check the graphs, they are all red x's. I check the graph debug and it states that the rrd's can not be found.

When I use the original templates, script, and xml, I can generate graphs and they get data and all that good stuff. The only problem I have with this is that the script is slow sometimes and cactid has issues with it after 296 seconds.

I would like to use your script with the orginal templates since your script is supposed to be faster.
