After upgrading to version 5.6.4. NagiosXI stopped reporting bandwidth of the interface, graphs come with a flat line.

Here an example:
/usr/local/nagios/libexec/check_rrdtraf -f /var/lib/mrtg/pdfirewall_500040110.rrd -w 5.00,5.00 -c 8.00,8.00 -l G
OK - Current BW in: 0Gbps Out: 0Gbps|in=0Gb/s;5.00;8.00 out=0Gb/s;5.00;8.00
Current is always 0, these is happening for switches and firewalls.

What OS and release is the Nagios server running?
First, make sure the Network Switch / Router wizard in XI is the latest version by logging in to the XI GUI and going to the Admin > Manage Config Wizards menu.
Click the Check for Updates button and update the Network Switch / Router wizard.
Then run the following as root to set the permissions of the files the wizard / plugin use to get the bandwidth information.
Code: Select all
chown apache:nagios /etc/mrtg -R
chmod 775 /etc/mrtg -R
chown apache:nagios /var/lib/mrtg -R
chmod 775 /var/lib/mrtg -R
Let the system run for 15 minutes and see if the issue has been resolved.
If the Bandwidth is still zero, try this, edit the /etc/cron.d/mrtg file and change this line from
Code: Select all
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok --user=nagios --group=nagios
to
Code: Select all
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok
Save the change and restart cron by running
Wait for 20 minutes and see if you start to see the bandwidth.

The changes did not produce any result.

Can you run the following commands as root and post the the /tmp/mrtg.txt file here so we can view it for any errors?
Code: Select all
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg -debug=cfg,base,log &> /tmp/mrtg.txt
LANG=C LC_ALL=C /usr/bin/mrtg &>> /tmp/mrtg.txt
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok &>> /tmp/mrtg.txt
{ time LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg 2>1 ; } 2>> /tmp/mrtg.txt
Thanks.

Attached find the results.
I have also tried to run a new wizard for a network device and it also reports bandwidth 0.
Thanks

I found these messages which is causing the MRTG process to exit before gathering the bandwidth data.
WARNING: "Title[10.4.0.71_8]" not specified
WARNING: "MaxBytes[10.4.0.71_8]" not specified
WARNING: I can't find a "target[10.4.0.71_8]" definition
ERROR: Please fix the error(s) in your config file
Go to the /etc/mrtg/conf.d folder and edit this file 10.4.0.71.cfg
Find this line and comment it out.
Save the change and run this command again to see if it filishes.
Code: Select all
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok
If not, fix the error and re-run it until all of them are fixed and the MRTG process should start to gather the bandwidth data again.

The bandwidth is now reporting on most devices, however, on one of firewalls, the aggregated interfaces it's not. It is back to the same issue we had last week...
