I was researching what our upgrade path would be to NPM 12 and had a question. Using the Upgrade Advisor, it says I upgrade NPM to 11.5.2 to 12.0 and then upgrade NTA from 4.1.1 to 4.2. I was curious about this because the compatibility table for NTA shows that 4.1.1 isn't compatible with 12.0, so wouldn't I need to…
Hi All, We got an issue. After we install NTA, Netflow Service make CPU load high. Netflow service takes up 30% CPU utilization. Is there any solution for this case? Below we attach screen capture Orion Server / Polling Server CPU Utilization. My environment is : 1. NPM 12.0 2. SAM 6.4.2 3. NCM 7.5 4. NTA 4.2.0 Thanks
I'm frequently getting a "No space left on your NTA Flow Storage disk" message the NTA summary page. I check NTA storage weekly but apparently this isn't often enough. Another concern is if I am managing space correctly. My installation of NTA is about 2 months old, and our network team is systematically going through our…
I know that the Vmware DVS supports Netflow, but have never actually seen it in the wild with NTA. Anyone done it and have any comments on it in terms of gotchas or did it just work without hassle?

ARGUS can watch local interfaces and stream a Netflow to a specific IP address and port, which is configured in a text file according to…
I want to do some analysis with the Network Traffic Analyzer sw but not sure what I need in terms of hardware. I hear references to dedicated machines for the "main poller" and "Database" machines, but I also hear about people running everything on a single VM. The network I want to analyze has 50-ish nodes overall, but…
i haven't opened a ticket yet but wanted to knwo if anybody else was seeing this issue. We keep losing the connection to the database. This is the error message I get. Connection to NTA Flow Storage Database has been lost. NTA cannot save any flows now I can restart the database server and it restores the connection. Then…
We have solarwinds in our environment and Net flow is working in most of our equipment, but not in the Nexus gear we have. I ran the configuration by Cisco and they said that it should work. I can see the Nexus sending information to the Solarwinds server, but the Solarwinds server does not know how to process, as far I…
I ran a report for top 10 applications used at a location. How do I map application traffic to a specific product? Is Microsoft-DS traffic Outlook traffic or is Simple Mail Transfer? What is - http protocol over TLS/SSL?
