Summary

Being able to view the status of your infrastructure from a web browser is a great very useful. Combined with an SSL-enabled web server, or by using a VPN, this functionality can allow people in your company to check the status of the entire network from any location in the world.

A large number of views can assist you in finding out what the root cause of a problem is. You can view objects by their groups, as well as by individual host or service.

If one or more hosts is down, then checking the network status on a 2D or 3D status map should be the first step you perform. There are also views for problems related to hosts and services that only show the direct causes of the problems, and skip issues that arise due to problems with other hosts or services.

The web interface also allows you to modify Nagio's behavior. It can also be used to configure individual hosts and services. You can also schedule host and service checks for a specified time. You can use this, for example, if you want to check whether the changes your team has performed will resolve current problems.

The web interface also allows you to schedule and manage host and service downtimes. You can also read, create, and manage comments associated with all objects.

Getting to know the web interface is really essential in order to use Nagios effectively.
