I have Nagios Network Analyzer running and an fprobe setup on a Linux server. I'm getting data but it isn't graphing

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

Host_Alias HOST = localhost

Cmnd_Alias LIST = /sbin/iptables --list
Cmnd_Alias SAVE = /etc/init.d/iptables save
Cmnd_Alias UPDATE = /sbin/iptables -I INPUT -p udp -j ACCEPT --dport *
Cmnd_Alias DAEMON = /usr/local/nagiosna/bin/nagiosna *

%nnacmd ALL=(ALL) NOPASSWD:SAVE

tcpdump is showing that it is getting data:

Is the date/time correct on the Nagios Network Analyzer box? Run "ntpdate pool.ntp.org" a couple of times to sync the time, restart each source from the web UI, wait for a while, and see if the graphs will appear.

I ran the ntpdate a couple of times and restarted the source. Left it for a couple of days. Still no graphs.

Can you please link your apache error_log after you click into the source? It may be permissions issues on the RRD file. The actual nfcpad data is being stored in it's own files which makes up the reports, queries, and top talkers while the bandwidth graph is made using the RRD file. If it can't read it or there's an error somewhere, it would return no data.

The apache error_log is reporting

Does the "bandwidth.rrd" actually exist and what are the permissions?

Code: Select all

ll /usr/local/nagiosna/var/
ll /usr/local/nagiosna/var/<your source>
Also run the following commands and show us the output:

Code: Select all

rrdtool -V

whereis rrdtool
