This wizard appears to have stopped functioning yesterday. It will now just hang at the 'scanning' stage. I am unsure of the logs I need to look at to troubleshoot further - which are they?

What is the Nagios XI version that you are currently using? What is the version of the switch/router wizard that you are using?

Admin->Manage Config Wizards

Have you done any changes to the system lately - configuration changes, upgrades, etc.?

Posted: **Fri Jul 18, 2014 5:25 am**

Wizard is version 2.0.6
XI is 2014R1.3-REV2812

I've done heaps of changes recently trying to figure out my perfdata problem including offloading MySQL, installing rrdcached and switching to a ramdisk.

Do you get any output when you run the following commands?

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
/usr/bin/cfgmaker --show-op-down --noreversedns --zero-speed '100000000' '<community>@<ip address>:::::2'

FYI, we had an issue with the latest tarball. I can see that your XI version is shown with the rev. number:

Code: Select all

XI is 2014R1.3-REV2812

To fix this, remove the old "nagiosxi" directory and the old tarball from "/tmp/", re-download the latest tarball, and re-run the "./upgrade" script. It shouldn't take long at all, but it will "fix" the version number that is shown in the XI web UI.

Thanks, Ludmil. Output as requested - No output from this one:

Just asking to make sure, but you did replace <community> and <ip> with their correct values, correct?

Posted: **Fri Jul 18, 2014 6:04 pm**

Depends what you mean by "correct"

I picked one of the switches I am monitoring - that right?

Posted: **Mon Jul 21, 2014 12:01 pm**

Provided you used the correct IP and community string combination, then yes I would consider that correct.(which I can see that you likely did use valid inputs about halfway through your result output) I think at this point either the cfgmaker script got messed up(not likely) or there are issues with your currently installed snmp prereqs for that same script. Could you post - /usr/bin/../lib/mrtg2/SNMP_util.pm which I assume should really be /usr/lib/mrtg2/SNMP_util.pm. This might end up being an issue with findbin or the binaries\perl modules that it is using on your system.
