Daily management and maintenance of Nagios

1, verify the correctness of the Nagios configuration file

Nagios to verify the configuration file in the very place, simply through a command to complete:/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/ Nagios.cfgnagios provides this validation feature, which usually prints out the wrong profile and which line in the file, which makes the Nagios configuration very easy, and the alert information is usually negligible because it is generally only recommended.

2, start and stop Nagios

(1) Boot Nagiosü start Nagios/etc/init.d/nagios start or service Nagios startü manually by initializing the script Nagios via Nagios command "D" parameter to start the Nagios daemon:/usr/local/nagios/bin/nagios-d/usr/local/nagios/etc/nagios.cfg

(2) Close Nagiosü Nagios Services/etc/init.d/nagios stop or service Nagios Stopü by initializing a script to shut down Nagioskill by means of kill <nagios_pid>

(3) Reboot the Nagiosü reboot the Nagios/etc/rc.d/init.d/nagios reload/etc/rc.d/init.d/nagios restartü the Web monitor page to reboot by initializing the script Nagios

3.nagios Performance Analysis Chart

(1) Nagios Performance Analysis chart role nagios to the service or host monitoring is a transient state, sometimes the system administrator if need to understand the host for a period of time performance and service response status, and the formation of a chart, you need to view the log data to analyze, but this way not only cumbersome, and abstract, but luckily, PnP can help us to do the job.

(2) The concept of PNP and the installation Environment PnP is a small open source package that is based on PHP and PERL,PNP can use the RRDtool tool to draw the data collected by Nagios into related charts, and then show how the host or service is running over a period of time. PNP Official website: http://www.pnp4nagios.org If you want to install PNP, you first need to install the following environment: 1: After the integration of the Apache PHP environment, you need to support GDZLIBJPEG2: Install RRDtool Tool 3: Install Perl

RRDtool is a graph generation tool that can get information from http://www.mrtg.org/rrdtool/. The version downloaded here is rrdtool-1.4.5.tar.gz,

The installation process is as follows:

[Root@nagios rrdtool]# tar zxvf rrdtool-1.4.5.tar.gz

[Root@nagios rrdtool]# CD rrdtool-1.4.5

[Root@nagios rrdtool-1.4.5]#./configure--perfix=/usr/local/rrdtool

[Root@nagios rrdtool-1.4.5]# make

[Root@nagios rrdtool-1.4.5]# make install
