Source settings are:
Sender IP Address*: 192.168.100.3
Listening Port*: 9991
Incoming Flow Type: NetFlow
Raw Data Lifetime: 48 hours

Any idea why it happen?
Thanks

How long did you wait between setting up the source, and opening this thread? It can take some time to get the first bit of data posted. Were you sure to add the right port on your source? I'd check on this.

It is forth day already and nothing. I am able see reports, disk usage increase that this mean data flow. Summary graph still show "No Data Available".

Run the following command and show us the output:

I'm having a similar issue:

cat /etc/sudoers.d/nna_conf
Defaults:%nnacmd !requiretty

Cmnd_Alias LIST = /sbin/iptables --list

tcpdump is showing that it is getting data:

nfcapd files are being generated. See attached screen capture. But no graphs.

I have locked this topic as it is several months old. Please open a new topic with your post. Initial thoughts would be to check php vs system time, make sure that your graph is only attempting to query data within the lifetime that the source stores it, and making sure that apache or the nagios group has proper access to those files.
