Monitor the End of the World (or any other event of your choosing) with Nagios XI!

Nagios XI is extremely flexible, perhaps more flexible than most people realize!

To showcase the flexibility of Nagios XI, President and Founder of Nagios – Ethan Galstad, has developed the plugin Doomsday Check  to monitor an arbitrary doomsday date (of your choosing) with customizable warning and critical thresholds.

Although this plugin may not be very practical in a networking environment, it’s fun to play around with and is definitely worth a try.

 

Service Status Detail

 

If you would like to use this plugin, simply download it here to your plugins directory (/usr/local/nagios/libexec/), make it executable (`chmod +x check_doomsday.php`), and create a service for it.

FREAK Vulnerability Tester

With yesterday’s disclosure of the new SSL/TLS vulnerability dubbed FREAK, we at Nagios decided to take some action to assist the community with a quick and easy tester to help determine if a server is vulnerable to (CVE-2015-0204).

If you are not familiar with the FREAK Vulnerability, here is a brief description from https://freakattack.com/ :

A connection is vulnerable if the server accepts RSA_EXPORT cipher suites and the client either offers an RSA_EXPORT suite or is using a version of OpenSSL that is vulnerable to CVE-2015-0204. Vulnerable clients include many Google and Apple devices (which use unpatched OpenSSL), a large number of embedded systems, and many other software products that use TLS behind the scenes without disabling the vulnerable cryptographic suites.

 

At Nagios, we take security vulnerabilities very seriously and when possible like to offer the ability to perform a quick check directly from our website.

Enter FREAK Vulnerability Tester (CVE-2015-0204)

Nagios Enterprises provides IT management solutions that monitor your network infrastructure, manage your network bandwidth, and can mitigate or even eliminate the effects of the FREAK Vulnerability as well as other security vulnerabilities.

For most servers that are found to be vulnerable administrators should be able to update the OpenSSL package and then restart the affected services such as httpd.

If your server is running RHEL or CentOS, the following commands will resolve the security vulnerability:

yum update openssl -y
service httpd restart

If you are already using Nagios Core or XI to monitor your infrastructure, this easy-to-use plugin can notify you if your system is susceptible to the FREAK vulnerability.

Nagios XI VMware Virtualization Wizard Released

Nagios Enterprises is excited to announce the release of the VMware Virtualization Wizard for Nagios XI.

The VMware Virtualization Wizard monitors your VMware virtual environment by offloading the VMware checks to a vSphere Management Assistance (vMA) appliance.

This is achieved by utilizing the plugin box293_check_vmware, which has been written specifically for use on the vMA. Troy Lea (the author of box293_check_vmware) received a lot of feedback at the VMworld Conference after giving his talk on the plugin.

Why use the box293_check_vmware plugin? The plugin utilizes the VMware SDK. The SDK is notoriously CPU and Memory hungry, which can easily overload and cripple your Nagios XI host. By offloading the plugin to the vMA appliance, your Nagios XI server will not be affected as you monitor your VMware virtual environment.

The VMware Virtualization Wizard and installation instructions are available for download from the Nagios Exchange.
