Nagios Introduction
Nagios is an Open-source application used to monitor systems and networks, typically running on a master server running Liunx or Unix operating systems. Nagios uses its numerous plug-ins to realize the monitoring of the local and remote service, when the object of the monitor is abnormal, Nagios wi

So far, 413 hosts and 754 services have been monitored.Although Nagios is very useful, it is difficult to configure it. I can give it a Chinese name based on its pronunciation-it is hard to die.

Although Nagios is very useful, but the configuration is indeed trouble, according to its pronunciation I give it a Chinese name-hard enough to die. For this reason, I will be as detailed as possible to tell you I use Nagios process and experience, I hope to help beginners.

the problem can be a message to the poor Yun-Wei classmate called up to restore services. This matter, Nagios is basically the best solution. It has a wide variety of plug-ins, and writing custom plug-ins is extremely simple, can easily monitor from the operating system to the application of all aspects. Its configuration file is simple and easy to understand, and very powerful, a little familiar can easily according to their own needs to configure.F

Build a printer monitoring server using nagios and monitor the nagios printer
Tutorial Background: The company has many HP printers, which are difficult to manage. So I thought about whether I could be a printer monitoring server to quickly respond to all the printer problems. After that, I checked the relevant information on the Internet and set up one, so there was no problem in using it. I shared it with

Environment: install Centos according to this guide. the installation directory is as follows: installing Nagios and plug-ins to/usr/local/nagios will be configured as the Web interface for monitoring several main services (such as CPU load and disk utilization) of the local system: http://localhost/nagios/ 2

If "NRPE v2.12" is displayed, it indicates that NRPE can communicate with the monitored end normally.
After the installation is complete, start the configuration. See

. Nagiosql can customize the file structure, continue the previous configuration structure, and generate configuration by IP Address4. Nagiosql backs up the configuration of each configuration change and stores it with a timestamp suffix. In theory, it can be rolled back to any historical configuration.

A company's project website was launched for a few days because the disk was full and there was a problem. Because its servers were concentrated in a certain IDC, we considered deploying a Nagios monitoring and alarm system, since other project websites may have similar requirements, the installation process should be compiled into scripts to facilitate future work. The automatic installation script of the Nagios
Center server reads the instructions in the configuration file to communicate with the remote daemon and instructs the remote daemon to perform the necessary checks. Although Nagios software must be run on a Linux or Unix operating system, the remotely monitored machine can be any host that can communicate with it, and Naigos will respond to the configuration based on the response returned by the remote host, and
NagiosQL is a web graphical management application designed for nagios. It operates databases and configuration files, including writing configuration file information to databases, modify the monitoring configuration of Nagios in the database and update the configuration stored in the database to the file. You can directly modify the configuration on the Web page provided by NagiosQL. The implementation ar
apache, just install it. After installation, check whether it works properly.
After learning how Nagios manages server objects through plug-ins, I am now studying how Nagios manages Remote Server objects. The Nagios system provides a plug-in named NRPE. Nagios periodically runs it to obtain various status information
