Software Introduction:

Nagios is an open-source monitoring system that can be run on the Linux/unix platform to monitor system health and network information. Nagios can monitor the specified local or remote host as well as services, while providing exception notification functionality.

Nagios provides the following monitoring capabilities.

• Monitor network Services (SMTP, POP3, HTTP, NNTP, Ping, and so on).

• Monitor host resources (processor load, disk utilization, and so on).

• Simple plug-in design allows users to easily expand their own service detection methods.

• Parallel service check mechanism.

• The ability to define network hierarchies and the use of "parent" host definitions to express relationships between network hosts can be used to discover and clarify host outages or unreachable states.

• Send alerts to Contacts when a service or host problem arises and resolves (by email, SMS, user-defined method).

• With the ability to define event handling, you can get more problem targeting when a host or service event occurs.

• Automatic log rollback.

• Redundancy monitoring of the host can be supported and implemented.

• The optional web interface is used to view the current network status, notification and fault history, log files, and so on.

The best place to use Nagios is that it will be the daily work of the administrator to automate, you only need to set the port to listen to, it will silently work, to help regularly to detect the status of the service port, once the problem is detected, the alarm will be issued in a timely manner. An alarm can be an email or a phone, which allows the administrator to receive the system's status the first time.
