We’ve had a lot of folks ask about Nagios’ capability of monitoring Microsoft Exchange servers. There are a number of plugins that have been capable of doing so for a while now, but our customers wanted something easier. Thus, we decided to create a nice Exchange server monitoring wizard.
We’ve tested the wizard with Exchange Server 2010. If you’ve got an older version of Exchange, give it a try and let us know how it works for you!

We’ve had a number of customer requests for new Nagios XI wizards that make it easy to monitor Linux/Unix machines either by SSH (using check_by_ssh) or NRPE. This is often useful in environments where Nagios admins have already installed the Nagios plugins and/or NRPE on machine in order to monitor them with Nagios Core.
Due to the requests we received, we whipped together some new wizards that help with this. Specifically, the new SSH Proxy and NRPE wizards.
And lest I forget, we also had a great community member (thanks Joshua!) document and test instructions on monitoring AIX over NRPE. We worked with Joshua to develop the NRPE wizard in a way that would work with his AIX/NRPE setup. BTW: Would you believe using Nagios to monitor AIX could save $300k+ on Tivoli licenses?
We’ve had some requests in past months about developer documentation for writing custom Configuration Wizards for Nagios XI. Many admins have a large amount of devices of a specific type that they regularly need to add to their monitoring environment. So for those needing to write their own wizard, and don’t mind getting their hands dirty with PHP development, this document and example code illustrate how to write a monitoring wizard while maintaining the integrity of the Nagios XI framework. The example wizard utilizes a weather alerts check plugin written by Tony Yarusso. You can find the document on the Nagios Library.
Nagios XI has always had the ability to let you know when updates to the software are available, displaying a message under the Admin area that looks like this:
This is great for just checking up on from time to time, but for most system administrators there are too many applications to be manually checking for updates, and since the whole point of Nagios is to notify you when something needs attention, it would seem far more useful to set this up in a way that would actively let you know when an update was available.
The solution for this was to re-implement the software update check as a Nagios check plugin, separate from the page code. This means that you can now set up a Nagios service to watch for software updates to XI, and get alerts when a new version comes out just like you would for anything else that needed attention on your network, saving you time and making it more likely that you will actually remember to apply updates when they become available. With that configuration, you will also have a service screen that looks like this:
While not yet present in XI by default, you can easily add this functionality to your existing installations. Simply download the plugin here to your plugins directory (/usr/local/nagios/libexec/), make it executable (`chmod +x check_xi_updates`), and create a service for it. You can find more information about those steps in the documentation and from a self-paced training video (customers only).
