I see this has been covered but none of the posts are helping.
Running: PRTG Network Monitor 18.104.22.16879
Netflow V9 sensor has -> SETTINGS -> Stream Data to Disk (for Debugging) ON for Only for the 'Other' channel.
The C:\Program Files (x86)\PRTG Network Monitor\ directory has no StreamLog dir. There are no CSV files in any of the sub-dirs, no files with the word "stream" or "log".
I have turned on/off/on logging while restarting PRTG services in between.
I have left logging on and looked for a massive file, or hoped the server's disk would fill up - no this didn't happen.
PRTG Event Logs has nothing. Event Logs in general have nothing.
The NetFlow sensor is otherwise working OK.
Anyone experience this before?
