Nagios之web界面管理工具Nagiosql安装

发布时间：June 4, 2012 // 分类：Nagios // No Comments

NagiosQL是一个基于Web界面的Nagios配置管理工具，极大方便Nagios的使用、管理。
下载安装Nagiosql：

cd /var/www/html/

wget http://nchc.dl.sourceforge.net/project/nagiosql/nagiosql/NagiosQL%203.2.0/nagiosql_320.tar.gz

tar zxvf nagiosql_320.tar.gz

mv nagiosql32/ nagiosql

chmod -R 777 /var/www/html/nagiosql/config/

目录权限配置：

mkdir -p /etc/nagiosql/backup/hosts

mkdir -p /etc/nagiosql/backup/services

mkdir -p /etc/nagiosql/hosts

mkdir -p /etc/nagiosql/services

chown -R nagios:apache /etc/nagiosql/

chown -R nagios:apache /usr/local/nagios/etc/

chown nagios:apache /usr/local/nagios/bin/nagios

chown nagios:apache /usr/local/nagios/var/rw/nagios.cmd

chown -R nagios:apache /usr/local/nagios/var/spool/checkresults

编辑nagios配置文件，注释以cfg开头的配置，并添加：

vim /usr/local/nagios/etc/nagios.cfg

## Timeperiods

cfg_file=/etc/nagiosql/timeperiods.cfg

## Commands

cfg_file=/etc/nagiosql/commands.cfg

## Contacts

cfg_file=/etc/nagiosql/contacts.cfg

cfg_file=/etc/nagiosql/contactgroups.cfg

cfg_file=/etc/nagiosql/contacttemplates.cfg

## Hosts

cfg_dir=/etc/nagiosql/hosts

cfg_file=/etc/nagiosql/hosttemplates.cfg

cfg_file=/etc/nagiosql/hostgroups.cfg

cfg_file=/etc/nagiosql/hostextinfo.cfg

cfg_file=/etc/nagiosql/hostescalations.cfg

cfg_file=/etc/nagiosql/hostdependencies.cfg

## Services

cfg_dir=/etc/nagiosql/services

cfg_file=/etc/nagiosql/servicetemplates.cfg

cfg_file=/etc/nagiosql/serviceextinfo.cfg

cfg_file=/etc/nagiosql/serviceescalations.cfg

cfg_file=/etc/nagiosql/servicedependencies.cfg

Nagios配置pnp4nagios支持图表显示

发布时间：June 3, 2012 // 分类：Nagios // No Comments

Nagios配合pnp4nagios可实现类似Cacti的图表显示，便于管理和分析服务器运行状况。
Nagios安装请参考：http://www.haiyun.me/archives/centos-install-nagios.html
安装rrdtool，需安装epel源：

#http://www.haiyun.me

yum install rrdtools perl-rrdtool perl-Time-HiRes

安装php4nagios：

wget http://nchc.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.17.tar.gz

tar zxvf pnp4nagios-0.6.17.tar.gz

cd pnp4nagios-0.6.17

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make all

make install

make install-webconf

make install-config

make install-init

#make fullinstall #相当于上面3个指令

配置php4nagios：

#http://www.haiyun.me

cd /usr/local/pnp4nagios/etc/

mv misccommands.cfg-sample misccommands.cfg

mv rra.cfg-sample rra.cfg

mv nagios.cfg-sample nagios.cfg

cd pages/

mv web_traffic.cfg-sample web_traffic.cfg

cd ../check_commands/

mv check_all_local_disks.cfg-sample check_all_local_disks.cfg

mv check_nrpe.cfg-sample check_nrpe.cfg

mv check_nwstat.cfg-sample check_nwstat.cfg

/etc/init.d/npcd start

chkconfig npcd on

配置Nagios数据输出接口：

vim /usr/local/nagios/etc/nagios.cfg

process_performance_data=1 #默认为0，修改为1

host_perfdata_command=process-host-perfdata #注释开头#号

service_perfdata_command=process-service-perfdata #注释开头#号

替换commands.cfg命令process-service-perfdata为以下内容：

vim /usr/local/nagios/etc/objects/commands.cfg

# 'process-host-perfdata' command definition

define command{

command_name    process-host-perfdata

command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA

}

# 'process-service-perfdata' command definition

define command{

command_name    process-service-perfdata

command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl

}                             

在模板配置文件中添加图表图标模板：

#http://www.haiyun.me

vim /usr/local/nagios/etc/objects/templates.cfg

define host {

name          host-pnp

action_url    /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_

register   0

}

define service {

name         service-pnp

action_url   /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$

register   0

}

复制鼠标悬停图标显示文件：

cp /usr/local/pnp4nagios/contrib/ssi/* /usr/local/nagios/share/ssi/

在监控主机或服务中调用图表模板：

define host{

use                     linux-server,host-pnp                          

host_name               localhost

alias                   localhost

address                 127.0.0.1

}

define service{

use                             local-service,service-pnp

host_name                       localhost

service_description             PING

check_command           check_ping!100.0,20%!500.0,60%

}

define service{

use                             local-service,service-pnp

host_name                       localhost

service_description             Root Partition

check_command           check_local_disk!20%!10%!/

}

重启nagios，访问nagios界面即可看到图表小图标：
nagios图表图标.png
点击图标会显示pnp4nagios测试页面：
pnp4nagios测试页面.png
全是绿色代表配置正常，然后移除或修改install.php文件：

1

rm -rf /usr/local/pnp4nagios/share/install.php

再次点击图标就会显示当前监控服务由pnp4nagios生成的图表了：

注意 ： 其实上面测试是没数据的 而且还会一直报错

后来发现是模式的问题。至于原来的模式为啥有问题，网上很多人反映是版本的问题。后来我把模式换成

.Bulk Mode with NPCD 就好了，而且官网文档也是推荐这种的。

参考文档：http://www.kar-chan.com/?p=2267

3.Bulk Mode with NPCD

  • 工作原理

从名字上可以看出，这种模式和Bulk是差不多的，只是多了一步将性能数据加上时间戳移到spool目录中等待处理，npcd服务调用process_perfdata.pl对数据进行处理

  • 配置参考

编辑nagios.cfg,加入或修改如下选项

process_performance_data=1
# service performance data
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file
# host performance data starting with Nagios 3.0
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

编辑commands.cfg,加入或修改如下选项

define command{        command_name    process-service-perfdata-file        command_line    /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$
}
define command{        command_name    process-host-perfdata-file        command_line    /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$
}

这次重装让我更熟悉nagios，很多都忘了，所以还搞了一天！惭愧！

譬如检测存活的 check_alive
