[XML] Cisco SAA Jitter/Jitter-error/http template

[jeanvav]

dent, you can just add threshold command and cacti will grab it. Also, if you do not set one up it will default to 5000.

Code: Select all

rtr 7
 type jitter dest-ipaddr 10.10.10.10 dest-port 61 num-packets 50 interval 1
 request-data-size 60
 threshold 30
 tag where are you
 frequency 300
rtr schedule 7 life forever start-time now

koike, have you tried copying any configs in this thread? Note that you have to setup schedule to run forever or something of long value.

[koike]

The router doesn't have the [forever] keyword.
So i try 0 from <0-2147483647>

IOS 12.0(5)T1

[dent]

Just some other stuff I've learned about SAA that I thought I'd share in case anyone else is new to this like I was:

You need to turn on 'rtr responder' on both the source and destination routers.

The SAA responder in different IOS versions has different capabilities - for example, if you want one-way delay measurements, you need IOS 12.2(2)T or better. If you want "SAA Engine" 2.x or better, I think you need IOS 12.2(13)T or better.

If you're measuring one-way delay, your two routers need to be time-synchronized (!)

[Guest]

Could someone provide some config examples required to provide the data to populate the graph templates provided?

THanks

[dent]

OK, in this example a source router (10.1.1.1) will be sending probes to a destination router (10.2.2.2) to simulate a voice call so we can measure jitter (variation in delay). Presumedly, these two routers are connected directly to one another via a T1 or some other WAN link. (Your probes can be several hops apart from each other, but in this example I wanted to measure the jitter over a specific link, not the complete end-to-end path.)

On the source router configure:

Code: Select all

rtr responder
rtr 1
 type jitter dest-ipaddr 10.2.2.2 dest-port 16001 codec g711alaw
 tos 32
 threshold 30
 tag rtr 1
rtr schedule 1 life forever start-time now

On the destination router, configure:

Code: Select all

rtr responder

In my case, both routers are running IOS 12.3, but I think 12.2(15) would work as well.

After this is set up, configure Cacti to query the source router (10.1.1.1) using the tag value from the router config ("rtr 1" in this case) as the index. (You could have multiple SAA probes running on the same router doing different things, so this is how you distinguish between them.)

After some time collecting data, you might see something like the attached graph for a link where QoS is configured on both ends and there are no problems with jitter to mess up your IP Voice calls.

Hope this isn't too simplistic for your needs...

Hi Dent,

Thanks for the information you provided.

Following this, I get a RTT Max and RTT MIN, but no RTT AVE.

Any suggestions?

[stelaras1]

i am using SAA xml from http://www.eatworms.org.uk/cacti/cisco-saa.php and http://forums.cacti.net/about4136-0-asc-0.html

and i have the following problem.

RRD file cannot be created and when i check Data Sources for this query i see in Index Type--> "Data query data sources must be created through New Graph" and there in No Index Value.
I have also noticed that when i check a rtr record in Data Query (Cisco - SAA Response Times or Data Query [Cisco - SAA Statistics) it does not go in grey (inactive) state but remain black , which means i can pick it again.


any ideas please...

thank you

I'm relatively new to Cacti so please bear with me.
There is one thing i don't understand. I've imported the file cacti_data_query_cisco_saa_632.xml which seem to work fine. This template defines a data template and graph templates(?) This file also contains reference to cisco_saa.xlm which I also downloaded. This file contains the snmp information, which lead me to believe that I need both files in order to get this to work?

Under graph management I'm now able to add a graph with one of the graph templates defined in cacti_data_query_cisco_saa_632.xml. I'm also able to choose the different data sources for each graph item. There is now return from the RRDTool when i turn on graph debug mode, which is the case on some of the pre-defines ones.

I've also defined a Data Query for my host running the SAA agent. This query returns no values/data
Data Query Debug Information:
+ Running data query [19].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/cacti_data_query_cisco_saa_632.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ ''
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/cacti_data_query_cisco_saa_632.xml'

+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/cacti_data_query_cisco_saa_632.xml'

I've runed a standard snmpgetnext from command line using one of the OID's defined in the cisco_saa.xml, and this works fine.

Have I missed something?

Anyone?

Hi,

Can anyone help me in graphing the following :
- Jitter ( All values ) OIDS
-RTT ( All Values ) OIDS

I need also to know the threshold of a better performance.

[Haakon]

Found out that the rrd files was not created. When rrd's are created manually, it all works fine.
yousry elfowey: Regarding the thresholds. Jitter performance depend on your Cisco QoS setting and SAA set up. Using test packets on high priority ports gives you 'better' values than on non priority ports.
RTT/Latency depend on QoS/SAA set up, but also your transmission media.

SAA gives you a number if jitter values:

Jitter Values:
NumOfJitterSamples: 99
MinOfPositivesSD: 1 MaxOfPositivesSD: 9
NumOfPositivesSD: 18 SumOfPositivesSD: 44 Sum2PositivesSD: 242
MinOfNegativesSD: 1 MaxOfNegativesSD: 10
NumOfNegativesSD: 15 SumOfNegativesSD: 43 Sum2NegativesSD: 261
MinOfPositivesDS: 1 MaxOfPositivesDS: 18
NumOfPositivesDS: 23 SumOfPositivesDS: 64 Sum2PositivesDS: 552
MinOfNegativesDS: 1 MaxOfNegativesDS: 19
NumOfNegativesDS: 21 SumOfNegativesDS: 62 Sum2NegativesDS: 648

This script queries +SDmax, +DSmax, -SDmax, -DSmax.
Using this, your graphs will reflect 'worst case jitter'. Mean jitter should should be calculated like this:

SumOfPositivesSD/NumOfPositivesSD
SumOfNegativesSD/NumOfNegativesSD
SumOfPositivesDS/NumOfPositivesDS
SumOfNegativesDS/NumOfNegativesDS

Download the RTTMON MIB and use a MIB browser to find your OID's

I need to know what is Number Of RTT: 785 ( i think 3000 Pkt sent every 60 Sec.
I need to understands what is happening.
I think router send 3000 Pck to simulate voice packet every 60 sec with interpacket interval 20 ms, is this correct ?
i need to understand statistics in more details.

I hope someone can help me understanding what is going on.

Hi Guys,

our ISP provided us a Router with CISCO SAA / RTT Functionality. The RTT / SAA Parameters are provided per Class of Service, so we would be able to measure Jitter, RTT & Packet Loss per Class of Service.

So far so good!

I found this thread about SAA, downloaded the templates from this thread (see attached files).

I am new to Cacti, so please keep this in mind!

I tried to import the files attached via CACTI -> IMPORT TEMPLATE function. The IMPORT of tthe File "cacti_data_query_cisco_saa_632.xml" was successfull, but I am not able to IMPORT the File "cisco_saa.xml", CACTI doenst Report any Error, just reloads the SITE without any comment.

Can anyone help me with this? What do I make wrong?

Thanks inadvance for your Help Guys!

Cheers,
asen

Hi Asen!

I ran into the same issue...

I don't know if this was truly the "fix" or not, but I discovered that the cisco_saa.xml file was not in the ../resource/snmp_queries folder. I don't know why the import fails, but I merely copied the file manually to that location, and I'm now getting SAA graphs/info. Again, I'm not a programmer so I don't truly know if things are working as they should. I'll have to play with this config a bit more, however, it *seems* that things are indeed working after the manual copy. Good luck!
