Cisco CBWFQ monitoring

[itzsen]

I am new to Cacti, please bear my ignorance.

I can successfully map the CPU, memory, interface utilization using Cacti. Now i am trying to map the QoS configured on the WAN routers. I have used this script multiple times before and it worked. This time i get see the policy-maps but when i try to graph it, i get 'RRD data file does not exist'. This router is managed by ATT when they enable the MIB (only on request). I am suspecting its a MIB not configured correctly on the routers. Can someone please tell me what MIBs need to be enabled for the QoS scripts.

Hi,
You need this MIBs here:

"config" => ".1.3.6.1.4.1.9.9.166.1.7.1.1.1", # list of all configured QoS classes
"config_index" => ".1.3.6.1.4.1.9.9.166.1.5.1.1.2", # cbQosConfigIndex
"int_index" => ".1.3.6.1.4.1.9.9.166.1.1.1.1.4", # cbQosIfIndex
"policy_direction" => ".1.3.6.1.4.1.9.9.166.1.1.1.1.3", # cbQosPolicyDirection
"int_name" => ".1.3.6.1.2.1.31.1.1.1.1",
"int_description" => ".1.3.6.1.2.1.31.1.1.1.18",
"class_traffic" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.11",
"pre_class_traffic" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.7",
"drop_class_traffic" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.18",
"drop_class_byte" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.17",
"pre_class_byte" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.6",
"class_byte" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.10",

Hi!!

I monitor some routers and I need to know the traffic of my QOS. I have found this two OID :

cbQosCMPostPolicyBitRate 1.3.6.1.4.1.9.9.166.1.15.1.1.11
And
cbQosCMPrePolicyBitRate 1.3.6.1.4.1.9.9.166.1.15.1.1.7

But, when I compare with my other plugin which display the traffic in and out of my router I see that the traffic of my qos is just for the traffic_out.

I'm more interested in knowing what is the qos' traffic of my router for the traffic_in!

If there is another OID i'm interested because I haven't found it!

Thanks a lot,

[magzz69]

up?

[magzz69]

When I use this OID

service-policy [ output | input ] "policy-map-name"
1.3.6.1.4.1.9.9.166.1.6.1.1.1

I've got this result :

1063 = STRING: "WAN"
1073 = STRING: "ETH"

Which show us the traffic in/out.
But how can I use this values for having the QOS of my router for the traffic IN and out.

Same problem, I use also the mib
"class_traffic" => ".1.3.6.1.4.1.9.9.166.1.15.1.1.11" to do SNMP request to a router, but I have not found if it is for the traffic IN or OUT (of the class), or the sum.

[magzz69]

.1.3.6.1.4.1.9.9.166.1.15.1.1.11 is the cbQosCMPostPolicyBitRate so it's the traffic of your qos' class in bytes/sec

But We don't know if it's traffic in or out and also how to have the 2 traffics...

I've been using this template for over a year now and it's working great.
However, recently I encountereed some strange problems that took me quite some time to solve. I thought I might post it here so others might benefit from it. Anyway, this is what happened:

I added a new policy-map to a tunnel-interface on one of my routers and afterwards I noticed that I was not able to create the graphs for it in Cacti. Everything seemed to work fine (I could see the classes etc.), but when I wanted to add the graphs, the RRD files simply weren't created at all.

The really weird part was that I already had some cbwfq-graphs running for the very same router (a different policy on a different interface) and those graphs kept working fine. However, when I removed one of those older graphs and tried to recreate it, the same thing happened: the RRD wasn't generated anymore.

After some investigating I found out the following:

The new policy-map I added looked like this:

Code: Select all

Policy-map QOS
 class GOLD
 bandwidth XXX
 class SILVER
 bandwidth XXX
 class BRONZE
 bandwidth XXX
 class class-default
 bandwidth XXX

policy-map SHAPE-QOS
 class class-default
  shape average XXXXXX
  service-policy QOS

interface Tunnel1
 service-policy output SHAPE-QOS

When I manually tried the script I saw this:

Code: Select all

perl /usr/local/share/cacti/scripts/cbwfq.pl [IP] [COMM] query
1953.1957:GOLD-QOS-Tunnel1
1953.1965:SILVER-QOS-Tunnel1
1953.1977:BRONZE-QOS-Tunnel1
1953.2007:class-default-QOS-Tunnel1
1953.2013:class-default-QOS-Tunnel1

Turned out that the reason it didn't work was that "class-default-QOS-Tunnel1" appeared twice in the list. The second occurrence should have been named "class-default-SHAPE-QOS-Tunnel1

The solution couldn't have been simpler: just remove and then re-apply the QOS policy within the SHAPE-QOS policy:

Code: Select all

policy-map SHAPE-QOS
 class class-default
  no service-policy QOS
  service-policy QOS

When I tested this time, the proper name was applied:

Code: Select all

perl /usr/local/share/cacti/scripts/cbwfq.pl [IP] [COMM] query
1953.2013:class-default-SHAPE-QOS-Tunnel1
1953.2069:GOLD-QOS-Tunnel1
1953.2077:SILVER-QOS-Tunnel1
1953.2089:BRONZE-QOS-Tunnel1
1953.2119:class-default-QOS-Tunnel1

From that moment on the graphs worked without a glitch!

...so it might just be a cisco-bug or something, I don't know.
Anyway, maybe some of you can put the above info to good use.

Anyone been able to do this using a pure xml snmp based query? I was thinking about trying it, but it doesnt seem like it is going to be easy. Just thought I would ask before I spent too much time. This script works for me, but I would like to get more stats out of the queries.

Thanks!

I have also the same idea in mind after I found out that existing solutions posted here do not work for me However I end up modifying one of the templates here for making it working for me.

G0dSmack, In case you already did a script using pure SNMP, please share it here

I'm attaching what I did for myself for making template working.

I'm attaching what I did for myself for making template working.

made some fixes:
* now it works with newer versions of net-snmp
* combined bytes/drops in one graph

hey,

i was also thinking to put drops/bytes on one graph however I afraid it will be hard to see drops when traffic is huge and you have only several drops.

what is new in net-snmp?

i was also thinking to put drops/bytes on one graph however I afraid it will be hard to see drops when traffic is huge and you have only several drops.

i think it's not so important to see actual form of drop graphs. what's more important is to see, if there are any drops are made. so a one pixel red line and numeric info at the bottom of graph would be more helpful. also, when there are a dozen of class-maps at one router, there are too many graphs, so why don't we cut them to half?

what is new in net-snmp?

net-snmp wants to have all parameters before host address. at least in my net-snmp on freebsd 7.2

also, i tried to show configured rate for each class-map in each policy, but there are lots of complications like dealing with parent maps, so i stuck halfway through implementing. well, may be i will make this work later.

.1.3.6.1.4.1.9.9.166.1.15.1.1.11 is the cbQosCMPostPolicyBitRate so it's the traffic of your qos' class in bytes/sec

But We don't know if it's traffic in or out and also how to have the 2 traffics...

hello guys,

Iam searching in this field ( monitoring both Inbound and Outbound for COS in the same graph ) where the main templete shows the outbound and the mib 1.3.6.1.4.1.9.9.166.1.15.1.1.11 related to cbQosCMPostPolicyBitRate ,
So i beileve that i have to create a custom graph templetes to calculate in traffic with the out traffic , in the first test i failed , so i wish to provide me with any idea regarding this field .

the second thing is how to consolidate different data sources in the same graph to draw the COS classifiers in the same graph??????

Does this script support nested policy maps?

Also, has anyone got a template to show shaping?

Cheers
