Re: Netpath through an A10 Load Balancer

3 of 3 people found this helpfulIt depends how the load balancer is configured. If the load balancer is transparently passing through traffic to various servers to host it, I would expect to see the servers. If it's doing full proxy where the load balancer terminates the TCP session and creates a new one to the server, I would expect the load balancer to be recognized as the destination. Here it looks like the destination according to the client is 172.30.13.233 and the only thing that responds to that IP is the VIP so I would expect NetPath to consider that the end of the path.

Hi Chris,
Thanks for your response. The LB here terminates the TCP session hence NetPath shows the VIP as the end of path. We are also observing some strange behavior on this NetPath service. Sometimes a very high latency number appears between the Load Balancer and the VIP. How could we identify the cause of the high latency? The A10 LB folks claim no such latency issues. Since Solarwinds is the new entity here, we are guilty till we provide evidence.
regards
Ravi

4 of 4 people found this helpfulWhen you're on the path page, append ?debug to the URL. Scroll down and click through the tabs to find some extra data. One thing you can review is the latency of individual paths that contribute to the multipath. That may help. If that doesn't get you what you need, I'd suggest a Wireshark on the probe to prove the latency. Wiresharks tend to be very persuasive.
