I figured this would be a good group to ask this question. We use Orion Netflow monitor to gather the general application/endpoint data. The problem is it doesn't provide in depth analysis when troubleshooting something like poor application performance across a WAN. Is it network latency? Is it a poorly written application? Is it the backend db? We previously had a software package by Opnet called ACE which could take in packet captures from things like Wireshark and provide you with an in-depth analysis of where the "slowdown" most likely is occurring.
My question is if anyone knows of another tool that is cheap and provides the in-depth network analysis that Orion Netflow doesn't. Opnet ACE was a pretty expensive tool to keep around and we don't require this in-depth analysis too often...but when we do we all know that the network is the first area to blame.
Thanks in advance for any advice!
