nagios插件pnp安装

1、安装rrdtool

# tar zxvf rrdtool-1.4.5.tar.gz && cd rrdtool-1.4.5 && ./configure --prefix=/usr/local/rrdtool && make && make install

2、安装pnp

tar zxvf pnp-0.4.13.tar.gz && cd pnp-0.4.13 && ./configure --with-nagios-user=nagios  --with-nagios-group=nagios  --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata && make all && make install && make install-config && make install-init 

 

安装完成,PNP默认文件放置情况如下:
General Options:
-----------------------------       -------------------
  Nagios user/group:                nagios nagios
  Install directory:                /usr/local/nagios
  HTML Dir:                         /usr/local/nagios/share/pnp
  Config Dir:                       /usr/local/nagios/etc/pnp
  Path to rrdtool:                  /usr/local/bin/rrdtool (Version 1.4.5)
  RRDs Perl Modules:                *** NOT FOUND ***
  RRD Files stored in:              /usr/local/nagios/share/perfdata
  process_perfdata.pl Logfile:      /usr/local/nagios/var/perfdata.log
  Perfdata files (NPCD) stored in:  /usr/local/nagios/var/spool/perfdata/
 
ps:RRDs Perl Modules:                *** NOT FOUND ***
在这里我遇到一个很奇怪的问题,由于没有安装rrds perl模块,导致pnp出图的数据是乱码,附上图片:

后来通过yum install rrdtool-perl就恢复正常了,有图有真相

3、配置PNP,创建默认配置文件
# cd /usr/local/nagios/etc/pnp/
# cp process_perfdata.cfg-sample process_perfdata.cfg
# cp npcd.cfg-sample npcd.cfg
# cp rra.cfg-sample rra.cfg
# chown -R nagios:nagios /usr/local/nagios/etc/pnp
修改process_perfdata.cfg文件
vim /usr/local/nagios/etc/pnp/process_perfdata.cfg
LOG_FILE = /usr/local/nagios/var/perfdata.log
#
# Loglevel 0=silent 1=normal 2=debug
#
LOG_LEVEL = 2
这里将日志级别改为2,即debug模式。
4、修改Nagios配置文件
1、增加小太阳图标
修改templates.cfg,增加一个定义PNP的host和service。修改后的内容如下:
define host {
  name       host-pnp
  register   0
#action_url /nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
action_url /nagios/pnp/index.php?host=$HOSTNAME$
process_perf_data 1
}
ps:我这里只添加了主机的小太阳图标,每当添加某主机的服务的时候,都会自动生成该服务的数据文件

2、修改commands.cfg,定义host-perfdata

 

define command{

       command_name  process-host-perfdata

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

       }

3、让主机引用host-perfdata

 

root># cat hosts.cfg 

define host{

        use     host-pnp        

        host_name               xx

        alias                    xx(x)

        address                  xx

        contact_groups            shyygroup

        check_command           check-host-alive

        max_check_attempts       5

        notification_interval       10

        notification_period        24x7

        notification_options       d,u,r

}

 

4、重启nagios服务后,在这个目录下会产生2个主机的目录

ls /usr/local/nagios/share/perfdata/

xxjshyy  xxysix

cd xxjshyy

ps:点击小太阳也能会报以下这种错误:

 

Deprecated: Assigning the return value of new by reference is deprecated in /usr/local/nagios/share/pnp/include/function.inc.php on line 1026

解决:

 

这是因为pnp-0.4.14对PHP 5.3.0的支持还不是很好,其中有几个bug需要修改:
根据错误提示打开
vi /usr/local/nagios/share/pnp/include/function.inc.php
找到行1541修改为
if($level == 2 && $type == "complete" && preg_match("/^NAGIOS_/",$tag)){
还会有两处错误需要修改,根据提示找到对应行进行修改:
line 556: 添加:date_default_timezone_set('UTC');
line 1032:修改为$pdf = new PDF('P', 'mm', 'A4'); 删除&
再重新重启nagios,应该就能看到图表了
