Nagios is helping us to implement the DevOps level Monitoring. Which provide the stemless feedback about our infrastructure. Bulk modification and log auditing help us a lot. Escalated and priority wise notification also help you to jump on the priority issue. Nagios XI is a top name under the automatic monitoring, It provide the enterprise level monitoring by which we can manage to monitor the applications, services or network. Any unexpected change in infrastructure service we are going the notice under the Dashboard. Dashboard can we customized according to the priority and need. The powerful monitoring engine provide the efficient and scalablity. The new web interface is also provide a lot of options to monitor the host, service or network on the same page. Nagios XI come up with the two edition and I recommend if you have to manage the number of host in a short time you must go with the enterprise edition as it's less time consuming.

Great product. Not only I learned something new, I was also able to impress the management with the results of this $0 product. I implemented a free version of the application to monitor my complex network, spreadout across multiple locations. While it took me several attempts to get it right, once installed, I was pleasanty surprised with what I saw. Having my network distributed across multiple locations, it was hard to monitor the upstate / resources of my servers and other network devices. Once I configure Nagious to my liking, I had every network device that I wanted to monitor on the consolidated map. Very simple configuration of the config files, once you get an idea of how to work them. Really great result for a free product
