Nagios Support Forum

Ok, I will try to test NNA in a machine always on. Thanks.

At this point I'm a little lost. I would like to clear a few things up. 1. How many sources did you set up in Nagios Network Analyzer? You should be setting up one source per device (1 for Windows and 1 for Linux). 2. Are either of your hosts working at this point? It sounds like your Windows host ...

So you are not receiving anything still with the tcpdump? Are you sure there's not something in the middle blocking it? No, I NNA doesn't receive data and I'm sure that in the middle is nothing. Try running the fprobe command and then run the following to see what the error message is. grep fprobe ...

Try running the fprobe command on the remote linux system like below and see if the NA server starts to receive data. fprobe -K18 192.168.10.99:2055 This is the explanation of the -K option. -K <bytes> Link layer header size. By default fprobe take this information from libpcap, but sometimes obtai...

`grep fprobe /var/log/messages` Re: the Windows problem, try restarting 1 thing at a time. Next time try the Windows service without restarting NNA. NNA is typically very stable and doesn't require restarting. [root@linux user]# grep fprobe /var/log/messages Nov 3 14:03:28 linux fprobe[10228]: [CRI...

Try and restart the flow service on the windows system to see if it starts to send data to the NA server. Maybe it stopped sending when the NA server was off. If after resume NNA VM I restart "flowExportService" service on Windows, NNA get data again. On the NA server, can you run the fol...

I suspect that your fprobe installation just straight up failed. ls -l /usr/local/sbin If there isn't a file in there called fprobe that is executable you need to re-run the installation and show us the output if it fails again. [user@linux ~]$ ls -l /usr/local/sbin/ total 92 -rwxr-xr-x. 1 root roo...

Now NNA collect data from Windows machine, thank you!! However... [user@linux ~]$ ps -aef | grep fprobe nagios 27774 27679 0 12:05 pts/0 00:00:00 grep --color=auto fprobe Edit: Top 5 Talkers doesn't show anything (Windows). I think isn't working again. In the field "Traffic last 30 minutes"...

Yes, reinstall the program solved that problem, now I see the service.

In Linux I have the same problem, I don't see anything:

Sorry, it may not be called "FlowTraq," that's just the people that make the software you installed: For Windows I also follow the PDF, but I choose "Flow Exporter" instead "nProbe". I did the next: It may be called "Flow Exporter." I honestly don't know. But...
