Experimental environment:

Virtual machine VMware Workstation 12 player

Server side: centos6.4 system, ip:192.168.0.24 netmask:255.255.255.0

Nagios 3.5.1

System default yum source apache server

Software introduction:

Nagios is an open source monitoring system that can run on the Linux/Unix platform and can be used to monitor the running status of the system and network information. Nagios can monitor specified local or remote hosts and services, while providing exception notification.

Nagios can provide the following monitoring functions.

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

Monitor host resources (processor load, disk utilization, etc.).

The simple plug-in design allows users to easily expand the detection methods of their own services.

Parallel service checking mechanism.

Have the ability to define the network hierarchy and use the "parent" host definition to express the relationship between network hosts, which can be used to discover and clarify the downtime or unreachable state of the host.

Send alerts to contacts (via email, SMS, user-defined methods) when service or host problems are generated and resolved.

It has the function of defining event handling, which can obtain more problem location when the event of the host or service occurs.

Automatic log rollback.

The redundant monitoring of the host can be supported and realized.

The optional Web interface is used to view current network status, notification and failure history, log files, and so on.

The best use of Nagios is that it automates the work done by administrators every day. You just need to set the port to listen. It will work silently to help check the status of the service port regularly. Once a problem is found, an alarm will be issued in time. The alarm can be an e-mail or a mobile phone, so that the administrator can receive the status of the system the first time.

Execute the following script

#! / bin/bash

# This is nagios in centos6.4 autho install shell
