为nagios添加图表
1、安装组件yum install perl-Time-HiRes rrdtool
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
# 'process-host-perfdata' command definition
define command{
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl
}
# 'process-service-perfdata' command definition
define command{
command_name process-service-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl
}
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_data1
}
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
