QoS ??

ggroen

Hello,

does anyone know if you can see QoS with NTA or is it a feature request?

i am monitoring MPLS WAN connections and i want to know if my protocols flow through the correct QoS classes.

It's a feature request. It would help if you could explain the problem you're trying to solve, what information would be ideal, and how you would use that information to solve the problem.

Denny, The problem is that i use netflow to look into the protocol stream and see what is going over the network. I would like the possibility to see what the qos is of the package,

example: I have a voice call from an abroad office going to our head office through mpls. In the mpls network we specified qos. for troubleshooting i want to know if the protocol or datastream has the correct qos setting.
if not we have a deteriorated voice call quality and that is not acceptable.

With the information that comes from NTA incl the QOS settings. i can change the settings accordingly and make sure that every runs with the correct priority enabling a good voice quality and make sure that i meet my SLA agreements

If your still interested, I've done kind of the same thing. While we can't see the tags for the individual conversations, we are able to monitor the total amount of traffic of specific tags. This will at least let you know if you're crossing your CIRs.

Here's the infor from the other post:

CISCO-CLASS-BASED-QOS-MIB:cbQosCMStatsTable

OID 1.3.6.1.4.1.9.9.166.1.15.1
Type SEQUENCE
Units
Access not-available
Status mandatory

This table specifies ClassMap related Statistical
information.

This one will show you how much traffic is being sent as each of your QoS tags. The trick to this one, though, is you need pull up the OID in the tool kit's MIB Browser so you can right click on its parent entry entry and display the table of stats. That will show you the parent & child indexes for each QoS policy on each interface. Adding the above OID.index.index into Orion (use the get, not get next to enter it) will let you track your QoS tag rate continually. Oh, and it looks like the indexes are unique to the device/interface/policy combo. Pain in the ...? defiantly, but great for VoIP systems using EF tags.

The SNMP Graph utility in the tool kit will let you add the entire table at once to the graph but this only lets you monitor it while you have the utility up.

This is a feature I would love to see as well.

I am the new network engineer for an electricity generation company in Australia and have previous (good) experience with the Solarwinds range of products. From my understanding Netflow exports ToS data and if this was captured by NTA (as it is with some other netflow analysis programs) it would be enough to get the company I am currently working for to implement the entire suite and get rid of the current array of different products that are currently doing the jobs.

As it is though it doesn't give us one of the main things we need and that is to easily see what data is being prioritized into which groups.

Hi,

We are currently trialing Orion with all plugins and one of the most important of these is the Netflow plugin for us as we are baselining out network for VOIP. We want to be able to do QoS analysis /reports from our Netflow data ( if Soalrwinds captures this field ? ) so we can see if any of our many apps. are tagging packets with CoS/ ToS values that would utilise our EF / Gold queues on our WAN links. The VOIP QoS channel would be monitored hopefully by Netflow with possibly alerting in place aswell ? Is their anyway of configuring the Netflow plugin or from any other Cisco Netflow config parameters that will allow us to see the QoS values set for particular ports / applications ?

Many thanks in advance

NTA does capture the ToS field. If you're not seeing it, you can go to Admin > Manage Views and add the ToS resources to your views.
