NagiosNA 2026R1 fresh install issue

[DVN]

Nagiosna shows "no data available" - I have waited more than 30min

I have netflow data from 2 sources, a Fortigate firewall and also a linux server.
Both sources are generating data, I can confirm using "nfdump -r flowfile" or "tcpdump dst port ####"

The /usr/local/nagiosna/var/bandwidth.rrd file also exists in both source folders

As user nna, running /usr/local/nagiosna/scripts/nagiosna stop, and then start, does show a unknown time unit '1W" error and wondered if this has something to do with it.

nna@nagiosna [/usr/local/nagiosna/scripts]
$ ./nagiosna stop
NagiosNA backend stopped.

nna@nagiosna [/usr/local/nagiosna/scripts]
$ ./nagiosna start
FirewallD is not running
FirewallD is not running
Unknown time unit '1W'
FirewallD is not running
FirewallD is not running
NagiosNA backend started...

I have tried RHEL9 and Centos9 builds, and get the same results.

Any insights would be greatly appreciated.

Resolved - built a server image using "minmal" versus Server with GUI.
Data sources now work.

My bad, hope this helps somebody who stumbles on this issue.

Good to know, I will take a look at the time issue however we do recommend using minimal installs. My guess to the no data displaying is that is a timezone offset so its not displaying the data yet. That would also account for the nagiosna service error you mentioned. The weird thing is that updating your time in the application should update your system time so I am curious what's installed in the gui that is interfering.

Thanks for the response. I did leave the system running for a few days, the no data symptom continued.
When we install systems, we do ensure the timezone is set correctly, including time sync.
I also ensured I set the correct System Timezone for the initial nagiosna "http://server/install" dialogue.

I can spin up another gui image and run some more tests if you have ideas?

I actually had the OVA image up (test) and compared packages between systems as well.
With the gui server, I noticed python wouldn't load rrdtool, and had to build it, but that was already part of the nagionsna build.
I never did try a yum remove on the disto package before running a nagiosna build. Will give that a try.
