Teach you to build and configure Nagios in Ubuntu 11.10

As we all know, Nagios is a monitoring system that monitors the state of the system and network information. Nagios can monitor the specified local or remote host and service, as well as provide exception notification capabilities. Nagios can be run on the Linux/unix platform, while providing an optional browser-based Web interface for system administrators to view network status, various system issues, and logs, and so on.

Main functional features of Nagios:

-Monitor network services (SMTP, POP3, HTTP, NNTP, ping, etc.)

-Monitor host resources (processes, disks, etc.)

-Simple plug-in design can easily extend the Nagios monitoring capabilities

-Concurrent processing of services such as monitoring

-Error notification function (via email, pager, or other user-defined method)

-You can specify a custom event-handling controller

-Optional Browser-based Web interface for system administrators to view network status, various system issues, logs, etc.

-can view system monitoring information via mobile phone

Today we will mainly introduce how to install the installation Nagios under the Unbuntu, specifically see below:
