This document describes how to automate adding and removing hosts and services in Nagios XI from the command line. Some administrators may have need to automate the process of adding and removing hosts and services in Nagios XI for use with cloud computing or large environments where solutions like Puppet or Chef may already be implemented. The procedures below outline how administrators can create their own automation solutions to safely add and remove hosts and services in Nagios XI while still maintaining the integrity of the monitoring environment.

Many customers, especially the ones running large environments, have been asking us what is the best way to clone a host along with its services. We have a great tool called “Bulk Host Import Wizard” which does just that.
You can learn more about this wizard by reading our “Nagios XI – Bulk Host Import Usage” document, posted on the Nagios Library.
You can download the wizard from the Nagios Exchange by following this link.
We often get questions about the kind of hardware requirements needed for a particular Nagios installation. As covered in a previous article, this is often a very difficult question to answer since monitoring environments differ so much. Most people assume that for a large Nagios installation, it’s a matter of simply adding enough CPU’s to the machine to handle the workload that it’s given. Although having enough CPU power is important, I’ve found that it’s ultimately not the biggest hardware limitation to the system. A large Nagios installation creates an enormous amount of disk activity, and if the hard disk can’t keep up with the constant traffic flow that needs to happen, all of those precious CPU’s are simply going to wait in line to be able to do what they need to do on the system. I’ve talked to some users who have spent some serious money on hardware to have insanely fast disks to handle their workload, but I wanted to do some experiments in-house for those users who may need to have better performance on a budget. I want to give special thanks to Nagios community members Dan Wittenberg and Max Schubert for documenting some of the tricks that you guys pioneered on this topic.

Managing a Nagios XI server is an important requirement to ensure that the monitoring server can be configured to meet organizational needs and that application updates (patches and upgrades) can be applied. Nagios XI servers that are placed on remote networks often requires that an administrator configures firewalls and routers to allow access to management features.
We wrote a short document that describes the requirements for and methods of managing remote Nagios XI servers. To learn more, read the document on Nagios Exchange.
