Back To Nagios XI Overview

Answers to Frequently Asked Questions (FAQs) regarding Nagios XI can be found here.


FAQs

What Are FAQS? Frequently Asked Questions, or "FAQs", are listed questions to frequently asked in some context, and pertain to a particular topic.

Fun Note: Since the acronym FAQ originated in textual media, its pronunciation varies - "fack," "fax," "facts," and "F.A.Q." are commonly heard. Depending on its usage, the term may refer specifically to a single frequently asked question, or to an assembled list of many questions and their answers.

Do these first

Nagios Admin Account Notifications Not Controlled Through XI
  • The nagiosadmin user was set to use the generic_template contact template, which resulted in notifications not being controlled through the XI interface.
    This can be corrected by changing the user's contact template to be xi_generic_template is the Core Config Manager. This bug was corrected in 2009R1.2 and only effects systems that had/have previous versions installed.

Distributed Monitoring

Is Nagios XI capable of Distributed Monitoring?

Yes, click here for the Distributed Monitoring Documentation

Performance Graphs Are Missing Or Not Displayed

This can happen for a variety of reasons, but there are several simple solutions that resolve this issue for most people:

Core Config Manager Issues

Most of these are related to IE's implementation of JavaScript. If possible, use a browser that more closely implements the ECMAScript Language Specification.

Missing Email Alerts

This can happen for a variety of reasons:

  • The nagiosadmin is set to use the generic_template contact template.
    This should be xi_generic_template, and can be modified by using the Core Config Manager. This bug was corrected in 2009R1.2 and only effects systems that had/have previous versions installed.
  • Outbound SMTP connections may be blocked by your border firewall
  • Unauthenticated SMTP relaying may be denied somewhere downstream - try switching email methods from Sendmail to SMTP in the admin section

SourceGuardian Errors

After upgrading to 2009R1.2C, some users started getting an error about SourceGuardian. Add this line to your /etc/php.ini file:

 extension=ixed.5.1.lin

Once you make that change, restart Apache:

 service restart httpd

Resolving "NSP: Sorry Dave, I can't let you do that" Errors

Session protection was added to 2009R1.2C to prevent CSRF attacks. This code to do this caused some users to see this error. The problem was due to the user's browser caching older versions of the XI javascript code. In order to clear the cache and prevent this from happening, you need to clear your browser's cache. This is typically done (in Firefox) by holding down the shift key and clicking reload. See Other well documented procedures on clearing the browser cache.

Login Keeps Redirecting

The web browser keeps redirecting to the login screen even after entering login credentials. This has been noticed in Internet Explorer.

Nagios XI uses cookies to save session state. These cookies are set to expire after 30 minutes. If the time on the Nagios XI server is incorrect, the cookies returned to the client's browser might appear to be expired due to the time difference between the client's computer and the Nagios XI server. Solution: Fix the time on the Nagios XI server to ensure it is correct.

Unable To Delete Hosts

Hosts can only be deleted after all of their dependent services and associated relationships have been deleted. Make sure to delete any associated services or other objects before deleting the host.
