I have installed the free SolarWinds Real-time Netflow analyzer. I managed to add the netflow device and all the interfaces that are configured with netflow export is reflected. There are in and out traffic reflected under the "traffic in/out" column but there is no "green" tick under "sending netflow" column. When i select one of the interface and click "Start flow capture", an error message pop out
"Netflow is not detected on the selected interface.
Please select another or configure the interface to send Netflow data to the host NetFlow Realtime is running on." (i wanted to paste the screen into this post but i was unable)
I find it strange that since the interfaces are reflected, that means Real-time Netflow analyzer has recieved netflow information from the configured device. I do not understand why i am getting the error message.
I got it working once by deleting and re-adding the device again. But the next day i execute the program again, it does not work. I tried to delete and re-add the device again, but this time it does not work. I rebooted the servers several times as well. I have check the router netflow settings by doing show ip flow export and the interfaces are exporting data correctly.
Please advice. Thanks.
