使用pnp4nagios为nagios数据绘图

主要是为ping值及丢包率绘图

1、download

2、

./configure --prefix=/usr/local/pnp4nagios \
--with-nagios-user=nagios \
--with-nagios-group=nagios \
--with-rrdtool=/usr/local/rrdtool-1.3.8/bin/rrdtool \
--with-perl_lib_path=/usr/local/rrdtool-1.3.8/lib/perl/5.8.8/i386-linux-thread-multi

Review the options above for accuracy.  If they look okay,
type 'make all' to compile.

make all
make install
make install-config

cp ./scripts/process_perfdata.pl /usr/local/nagios/libexec/
chown nagios.nagios /usr/local/nagios/libexec/process_perfdata.pl
chmod u+x /usr/local/nagios/libexec/process_perfdata.pl

3、/usr/local/nagios/etc/nagios.cfg

process_performance_data=1
service_perfdata_command=process-service-perfdata #取消该行注释

取消不需要的监控对象（service.cfg或host.cfg）添加以下定义：

（这个定义应该在定义每个service时就添加，否则默认为1）

define service {
   ...
   process_perf_data 0
   ...
}

替换掉command定义中的“process-service-perfdata”，定义为使用pnp所提供的脚本

define command{
command_name process-service-perfdata
command_line /usr/local/nagios/libexec/process_perfdata.pl
}

cp pnp4nagios-0.6.11/scripts/process_perfdata.pl /usr/local/nagios/libexec/process_perfdata.pl
chown nagios.nagios /usr/local/nagios/libexec/process_perfdata.pl
chmod u+x /usr/local/nagios/libexec/process_perfdata.pl

4、拷贝nginx的配置文件

cp ./sample-config/nginx.pnp4nagios.conf /usr/local/nginx/pnp4nagios.conf

5、访问：注意index.php后面要添加“/”

6、关于删除DiskFree,loadblance等不需要的图：

cd /usr/local/pnp4nagios/var/perfdata
for i in `find  .  -name DiskFree* -or -name LoadAverage*`;do mv $i $i.bak;done
