We can easily forward the Nagios log server to another destination by creating a new output in NLS.

Here at Bobcares, we have seen several such Nagios-related queries as part of our Server Management Services for web hosts and online service providers.

Today we’ll take a look at how to send Nagios core logs to the Nagios log server.

Know more about Nagios Log Server

Nagios Log Server is a powerful enterprise-class log monitoring and management application that allows organizations to view, sort, and configure logs.

Nagios Log Server systems are based on a clustering model. Each server in the cluster is called an Instance.

Usually, the log file is located at /usr/local/nagios/var/nagios.log or /var/log/nagios3/nagios.

By default, Nagios logs its events for the host and services in the /var/log/nagios/nagios path.

How we forward Nagios log server to another destination

Now let’s take a look at how our Support Engineers forward the Nagios log server to a different server. We can easily do it by creating a new output in NLS. Here are the steps that we follow.

1. First, in NLS, we navigate to Configure >> Global Config.
2. Next, we click on the Show Outputs button.
3. Here we select Add Output >> Custom.

4. Then we enter a name for the output.
5. After that, we enter a new output config as below:
udp {
host => ‘<ip of destination server>’
port => ‘514’
}
6. Finally, we click on the Save & Apply button.

This will take all of the information (as it is after it passes through the inputs/filters) and export it to <ip of destination server>:514 via UDP.
