The file contains host definitions and directives that dictate to Nagios what exactly to monitor. A basic host file for Nagios is fairly simple to create. In the directory /etc/nagios3/ conf.d/ you will find sample files with which you can build your network from. So let’s take a look at adding a server for Nagios to monitor.
What you will want to monitor is servers and other network devices. This is generally fine, because you are not going to be monitoring every desktop and device on your network. And by “manually” I do mean create configuration files for each host. Instead you have to manually enter hosts for monitoring. Nagios does not have any means of auto-discovery. This is one of those caveats I mentioned earlier. You will have to make sure that mail can be sent out on this server before this will work (beyond the scope of this article). The line you want to edit is:Įmail this to reflect the email address necessary. If you open up the /etc/nagios3/conf.d/contacts_nagios2.cfg file you will see you can set up an administrator for which alerts are sent. There isn’t too much system configuration that needs to be done with Nagios. You need to add some hosts before Nagios is really useful. What good is that on a large network? It’s not. Problem is, by default, Nagios will only see two hosts: localhost host and default gateway. To do this open up your browser and point it to When you hit that page you will see a welcome screen (see Figure 1) and a left navigation that will include all of the links you need to monitor your network. That’s it! Once this is done you are ready to take a look at a very bare-bones Nagios installation. You will use this to log in with user nagiosadmin Mark nagios, nagios-plugins, and nagios-plugins-extra for installation (which will catch all dependencies necessary).ĭuring the installation you will be asked for an administrative password. With the help of the Synaptic package manager, you can have Nagios installed in about a minute, if you follow these steps: If you do not already have it installed, the installation of Nagios will pick this requisite up. You will need to have the Apache web browser installed in order to use Nagios. To illustrate how simple Nagios is to install, I am going to demonstrate using Ubuntu (10.4 to be precise). Monitor network services (SMTP, POP3, HTTP, NNTP, Ping, and more)

In this article I am going to show you how to install Nagios and configure hosts and hostsgroups for easy monitoring.īefore we get into the thick of things, let’s take a peek at some of the features Nagios has to offer: But pound for pound, dollar for dollar, Nagios can’t be beat. It does have a few caveats that will cause some network administrators to shy away from. Does that mean Nagios is perfect? Not necessarily. Why? Nagios is powerful, flexible, does exactly what you tell it, and will always work when others fail. Nagios calls itself the “Industry standard in IT infrastructure monitoring.” It’s a bold statement, but anyone that has used Nagios, and used it correctly, they will happily agree with that statement. But there is one particular tool that does monitor networks and does an outstanding job of it. In the close-source, proprietary world you will find plenty of tools to handle this task: Packettrap, GFI Max, Spiceworks. They have seven devices all with the.In the enterprise environment, there are certain tools that are a necessity for administrators. They are an industrial manufacturer and therefore have very little control over the settings on the devices they must work with. I have a potential client who has asked me for a solution to a very unique network issue. 7 network devices with the same IP on the same network and can't change IPs Networking.Can anyone suggest the best aproach to set this up?
