Cisco SAA (IP SLA) Matrix...Anyone done it ?

[scottsta]

Hi all -

we have a requirement to implement a matrix based on the SAA Jitter and Latency info coming out of Cacti.

We have SAA query succesfully and populating RRD files, and can create and graph individual SITE A- SITE B latency and loss measures..

It would be extremely useful to visualize an overall site to site matrix showing latency and loss numbers...

While I think this might be difficult to do in Cacti - has anyone put together an external scripts which can parse the RRD files to present this info in either tabular or matrix format ??

many thanks

Hi, scottsta

Would you share your scripts? We have a need to do the same, but using Juniper routers insted of Cisco. It would require coding effort, and we could start more quickly from your work.

Best regards.

Take a look at network weathermap by Howie. You can use any data sources including Cisco IP SLA, and create a latency map.

In fact, I'm planning to make just such a map of my own network, showing per-hop latency and jitter, when I get a chance to plan all the appropriate IPSLA entries on my routers, and get it all into Cacti.

So if it turns out that you can't do it with Weathermap, you soon will be able to, because I want it too

Hi Howie

Long time, huh? I was looking for exactly the same: a network matrix "vision" of point-to-point performance information, with numbers of ping latency RTT, jitter like the Internet Health Report http://www.internethealthreport.com/ interface, using data from our own routers already monitored by Cacti.

Hi again Alex

You could do that, but for me the main benefit of using ip sla is that you can test per-link, so you know that it's the link between site 4 and site 7 that is bad, not just all the random things that happen to route that way at the moment.

For an end-user, I can see the use of the matrix view, but for diagnosing the fault, I think the ipsla/map view is better. Disagree?

Agreed. That's exactly what we need! The difference is that we don't have IP SLA in Juniper routers.

Agreed.
We have both internal (NOC) and external (End users) views of performance at our website: http://www.rnp.br/en/traffic/weathermap.php and http://www.rnp.br/en/traffic/index.html.

It would be useful to have a internal (NOC) view of performance numbers per link between nodes (that can also be publicly acessible for End users), but our End users would also request a public view to check performance data from all backbone nodes (check the weathermap URL above).

According to this post, there is something called Real-time Performance Monitor in JUNOS though... is it any good? (or did you know about it?)

Actually, here's the Juniper manual page too. Dunno how Juniper do optional features, or whether all routers would have this.

I didn't. Thanks! (Lack of time to research lately bacause of my masters degree course)

In general, JunOS is the same in almost all Juniper router platforms with few exceptions. Some features are available through additional interfaces like the "Tunnel Services PIC" (Adaptive Services PIC).

Howie,

Your idea sounds every interesting. I think I will have to try that out and see what shows up on my network. If I get around to it I will post the findings. I always say the closest you get to knowing 100% about your network, the better off you are troubleshooting it when a problem arises.
