为nagios添加图表-创新互联

1、安装组件

  yum install perl-Time-HiRes rrdtool  rrdtool-perl

2、安装pnp4nagios-0.6.24

  wget http://jaist.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.24.tar.gz

  tar zxvf pnp4nagios-0.6.24.tar.gz

  cd pnp4nagios-0.6.24

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

  make all

  make install

  make install-webconf

  make install-config

  make install-init

3、创建配置文件

  cd /usr/local/pnp4nagios/etc/

  mv misccommands.cfg-sample misccommands.cfg

  mv nagios.cfg-sample nagios.cfg

  mv rra.cfg-sample rra.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

4、重启服务

  service npcd restart

5、修改nagios配置档

  1）vi /usr/local/nagios/etc/nagios.cfg

   将process_performance_data=0  修改为  process_performance_data=1

   将以下两项的#去掉

   host_perfdata_command=process-host-perfdata

   service_perfdata_command=process-service-perfdata

  2）vi /usr/local/nagios/etc/objects/commands.cfg  添加以下内容

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.$TIMET$
}

   并将原有# 'process-host-perfdata' command definition、# 'process-service-perfdata' command definition注解删除！

  3）vi /usr/local/nagios/etc/objetcs/templates.cfg

   添加红色字体内容

define service{

    name              generic-service

    active_checks_enabled     1

    passive_checks_enabled     1

    parallelize_check       1

    obsess_over_service      1

    check_freshness        0

    notifications_enabled     1

    event_handler_enabled     1

    flap_detection_enabled     1

    failure_prediction_enabled   1

    process_perf_data       1

    retain_status_information   1

    retain_nonstatus_information  1

    is_volatile          0

    check_period          24x7

    max_check_attempts       3

    normal_check_interval     10

    retry_check_interval      2

    contact_groups         admins

    notification_options      w,u,c,r

    notification_interval     60

    notification_period      24x7

    register            0

    action_url    /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$

    process_perf_data 1

    }

  4）vi /usr/local/nagios/etc/nagios.cfg  修改参数如下

# Bulk / NPCD mode
# 

process_performance_data=1

# *** the template definition differs from the one in the original nagios.cfg
#
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

# *** the template definition differs from the one in the original nagios.cfg
#
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

6、检查配置是否有误

   /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

   重启服务

   service nagios restart

   service httpd restart

7、排错

   pnp4nagios输入用户名密码始终不正确具体解决方法

  是由于在安装pnp4nagios后在/etc/httpd/conf.d里，已经生成pnp4nagios.conf配置文件

  vi /etc/httpd/conf.d/pnp4nagios.conf  将AuthUserFile /usr/local/nagios/etc/htpasswd.user修改为  /usr/local/nagios/etc/htpasswd

  The requested URL /nagios/pnp4nagios/index.php/graph was not found on this server

 开启apache的php功能

vi /usr/local/httpd/conf/httpd.conf

     查找字符串AddType，并增加

     AddType application/x-httpd-php .php .php3 .htm .phtml .php4

     AddType application/x-httpd-php-source .phps

     查找字符串DirectoryIndex，并修改为

     DirectoryIndex index.html index.php3 index.php default.php

   将/etc/httpd/conf.d/pnp4nagios.conf所有内容复制到/etc/httpd/conf/httpd.conf后面

   service httpd restart

  perfdata directory "/usr/local/pnp4nagios/var/perfdata/localhost" for host "does not。。。。

  chown -R nagios.nagcmd /usr/local/pnp4nagios/var/
