No Data Available

Hi there,
I've started to work with network analyzer to replace an older tool we use. I've had it up and running for about 10 days now with a Linux box and just added to WAN routers. When going to 'sources' view I'm not seeing any graphs in the middle of the screen. Getting a 'No Data Available' , 'there is no data available for the currently selected time period'. I've left the default for the last 24 hours. Any thoughts on what's wrong here?

What type of device was being used in the example you gave? If you look further back is there data present? Is the source started? If so, is fprobe/what you are using to collate and send the flows to NNA running on that remote system? Is the port it's sending on open on the NNA server?

For the example I gave I'm using a RHEL VM, there is data present for the past 10 days, source has been started. I followed this documentation
http://assets.nagios.com/downloads/nagi ... alyzer.pdf
I also just added to WAN routers, but since I've just added them I'm assuming I won't be able to capture any graph data for the past 24 hours. I'm attaching a screen shot of what I have. Since I'm getting data, am I wrong to assume the ports are open on the NNA server?

I've also noted that the traffic for last 30 minutes isn't populating...

Is the device actually sending netflow data to your Nagios NA box? Can you see the data coming in if you run the following command on the NNA box?
Code: Select all
tcpdump -i eth0 port <the port to which the data is sent>

Hi there, I'm seeing data come across and am getting the top 5 charts updated just not the logrithmic and linear graphing or the past 30 minutes. I'm going to try and upgrade to see if that helps.

Let us know if you experience the same issue after the upgrade.

No luck, still can't get the last 30 minutes outage window or the graphs in the middle of this attachment. Any suggestions on what services to check and/or restart?
