There're some options like: perSONAR, OWAMP, Netnorad?. About the last one - it's a tool that was created by Facebook engineering to monitor their DC. The best thing about Netnorad is that the tool is able to randomize source port numbers, so the polarization problems wont occur. Dont know if perSONAR or OWAMP could to that. The downside of Netnorad is that it's just source code, or something like that - you need to to additional programing job to run it.
Maybe you guys have some recomendations of network performance monitoring ? Some othertools? Or some existing ones?
Thanks

hi,
are you looking for free or paid/licensed monitoring tools?
aside from solarwinds npm, i also like PRTG and OpManager

see useful link for testing opmanager:

You can also look at AKIPS.

thank you,
i think i described not exactly enough.
Im looking specifically for Network Bandwidth monitoring system, which is able to do end-to-end probing. Usualy one node acts like traffic generator, and other - responder.

For bandwidth and latency monitoring, you can use Nagios or Grafana. They are both free but you need to do some development with the software to tune it for your environment.

Hello, maybe i've described not correctly enough. What i need is not network monitoring system. I need Network performance tester for end-to-end network measurements. Something like perfSonar, or Netnorad. Have you any recommendations. The prerequisite is that the software would be able to randomize source ports to avoid loadbalancing-polarziation poblem where all traffic goes through one link.

thank you, maybe you know if it support something like source port number randomization - to avoid traffic measurement only on one link (polarization) ?

For your requirement, iPerf could be the one of the tools you want, HTH.
Best regards,

Thank you,
Can I ASK ?
How randomization DSCP values relates to load balancing ? Do DSCP values calculates into hash when load balancing process is active ?
1) Maybe Iperf can do port randomization, but we need some kind of system which do it always and gerenrates alerts, graphs and etc.
Thank you:)
