SNMP router/switch config wizard not working

[djcomber]

When I run the SNMP Router/Switch config wizard it shows a blank page.

I enter the IP address, SNMP community string and click next
The screen is then blank and does not move on even if I wait for 5 minutes.

This happens when I try a new router to monitor or try and configure new router to monitor.

What version of the wizard are you running?

[bwallace]

In addition to providing the version of the wizard as vAJ, suggested, what version of XI are you using and are you using the default switch/router wizard, or did you manually install it?
Reason I ask is this:

When plugins, components or wizards are not installed through the proper menus, this creates problems in Nagios XI, such as "wiping out" all wizards, so they can not be viewed in the Web interface, blank pages in the Web browser and other weird behaviors.

Hi Guys,

XI Version is 5.2.7
Wizard Network Switch/Router
Wizard Version is 2.3.0


The wizard is the default wizard.

It was working. the first page of the wizard shows, I enter the details for SNMP and the IP, hit next it says it's checking the device with the waiting indicator, then pops onto the next page but that is blank.

Run this command on your XI server in an SSH session:

Code: Select all

tail /var/log/httpd/error_log -f

Go and run the wizard to reproduce the problem.

Please post here the output produced in the SSH session.

Can you grab the versions of your installed SNMP packages?

Cent/RHEL:

Code: Select all

rpm -qa | grep snmp

Also OS distro & version:

Code: Select all

cat /etc/*-release
or
cat /proc/version

Follow-up questions:
1. You're certain that "nagios" is the configured SNMP community string?
2. Do you have any other switches or routers that you've configured successfully with the wizard?

[tgriep]

There is a bug found in the Network Switch / Router Wizard that could be causing the error you are getting.
If you login to to your XI server and edit this file

Code: Select all

/usr/local/nagiosxi/html/includes/configwizards/switch/switch.inc.php

Change line 42 from

Code: Select all

$snmpversion = (in_array($snmpversion, array("1", "2", "3")) ? $snmpversion : "1");

to

Code: Select all

$snmpversion = (in_array($snmpversion, array("1", "2c", "3")) ? $snmpversion : "1");

Save the file out and see the Network Switch / Router Wizard works for you.
Please post back your results.

I spoke to a dev about this and there was an issue with that wizard version of 2.3.0.

Before you do any t-shooting, upgrade it to the latest version of 2.3.1 - which might just resolve this -
Admin > System Extensions > Manage Config Wizards

Thanks - should have tried this first. Assumed (as always assumptions are the cause of many issues) that the wizards get updated with nagiosXI.

All working now as it did in the past.

Many thanks to those how replied.
