Can we find jitter, Latency ,and throughput type parameters using NPM?

michealrobert over 6 years ago

Hello, I have a GNS3 simulated network with 8 nodes. I have integrated GNS3 routers with NPM using a switch. Now I want to calculate the qos parameters when different types of traffic is transmitted over the network. Can NPM do that? Or should I go for other tool? If yes, how can I do that. It would be helpful, even if you can explain it in a vague way.

Yes, by custom polling OIDs involved: Example: https://supportforums.cisco.com/discussion/12036671/oid-ipsla-icmp-jitter You can also configure thresholds/ traps/ syslog stuff within IOS and have that…

Thanks for the reply. Do you any reference link/example on how to configure OID for IP SLA. Or any material on how to configure IP SLA to find qos for different traffic(http,video,voice..etc)

NTA module with NPM will give you all of your QOS info you are talking about.

If you SNMPwalk and the IOS is capable of reporting IPSLA metrics via SNMP, you'll see statistics (assuming SNMP works/ you see output from your SNMPwalk). Do you have other SolarWinds modules or just NPM?

Latency is the default NPM feature, QoS - is the NTA responsibility. To get jitter (min/max/avg) you have to use SNMP request to a special OID.

Thanks alexch. Can you please help me how to use SNMP to request OID with the following example. Suppose I have 2 routers, one is connected to and other to client. The client requests http traffic from server. So now should I connect a switch connecting both routers and connect a NTA to switch?And How to request snmp to request OID.? If you have any previous configurations, can you please post that. Please help me with this.

The connection scheme doesn't metter in this case - all devices should be reachable by IP from your Solarwinds instance. You can use a switch to connect Solarwinds to your network (as I've got you have to put it between routers). Then you need to find necessary OID (depends what statistics are you going to collect from router) in the router's vendor MIB DB (go to vendor site and search for MIB-browser). After that you can create your custom poller (search by "Universal Device Poller UNDP" in Solarwind web-site) based on the OID and create a graph/table or whatever you want in Solarwinds.

So, this can be made without solarwinds NPM and NTA right? I will try what you have said and might ask you a few doubts, kindly help .

What do you mean by "this"? NPM can collect statistic (via SNMP) according to a custom poller you did and draw a graphic based on collected information. You can also get a throughput statistic in NPM (it has the default interface pollers for it). By using NTa you can also get statistics about throughput, qos and top talkers - those information NTA gathers via NetFlow.
