No NTA data for latest 2020.2 RC3

nl4w0rk2017

Hello everyone,

I upgraded NPM and NTA to 2020.2 RC3. All seems to be working except NTA has no data. I was able to see netflow data coming from devices to the server Orion is installed using Wireshark. Is there any suggestion? I opened a support case also but still awaiting on responses.

Thanks,

Is the NTA service running on your Orion server? I had some issues upgrading from RC2 to RC3 with the service not wanting to actually start & run.

Yes, SolarWinds NetFlow Service is running.

I have that issue as well, with the NTA service not able to start on 2020.2 RC3 - How did you fix that?

Hi all,

Yes, NTA is working now.

Below were the errors that I had. I went in every node and deleted all the interfaces, then I re-add them again and NTA started to work again.
