Nagios图形化Pnp 安装和配置

⑴安装完nagios，继续安装pnp，要注意rrdtool的安装。

tar -xvzf pnp-0.4.13.tar.gz

cd pnp-0.4.13

./configure

make all

make install

make install-config

make install-init

---------------------------------------------------------------------------------

FAQ:

*** Configuration summary for pnp 0.4.13 02-19-2009 ***

  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 1.2.23)

  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/

-----------------------------------------

process_perfdata.pl 安装在 /usr/local/nagios/share/

配置示例文件安装在/usr/local/nagios/libexecs

config.php安装于/usr/local/nagios/etc/pnp

<a></a>

⑵修改配置文件

①

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 *

②

vi /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

#先改为2,为debug模式

③

修改etc/objects/templates.cfg增加新命令（增加小太阳标记）

#在use的后面添加"host-pnp"即可让监控图上的主机名称旁边增加一个小太阳的标记，点击此标记即可查看pnp图片。

define host {

        name       host-pnp

        register   0

        action_url /nagios/pnp/index.php?host=$HOSTNAME$

        process_perf_data               1

}

#还可以在service栏添加srv-pnp，添加后会在相应的栏内增加小太阳。

define service {

        name       srv-pnp

        action_url /nagios/pnp/index.php?host=$HOSTNAME$&amp;srv=$SERVICEDESC$

④

修改etc/nagios.cfg

找到如下几项，去掉注释

process_performance_data=1

host_perfdata_command=process-host-perfdata

service_perfdata_command=process-service-perfdata

⑤

修改commands.cfg

# 'process-host-perfdata' command definition

define command{

        command_name    process-host-perfdata

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

# 'process-service-perfdata' command definition

        command_name    process-service-perfdata

⑥nginx下的安全问题,需作如下配置

修改pnp的web服务器配置文件nginx.conf,请注意安全问题，我这里未做安全验证。

location /pnp/ {

root /usr/local/nagios/share/;

location ~ .*/.php?$

     {

  #fastcgi_pass  unix:/tmp/php-cgi.sock;

  fastcgi_pass  127.0.0.1:9000;

  fastcgi_index index.php;

  include fcgi.conf;

     }

如果开启了open_basedir还需修改php.ini

open_basedir =

"/opt/htdoc:/opt/php/lib/php:/tmp/session:/tmp/upload:/usr/local/nagios/share/pnp:/usr/local/nagios/etc/pnp:/usr/local/nagios/share/perfdata:/usr/local/rrdtool/bin/rrdtool

㈢测试：

为localhost这台主机在主机图标旁边添加个小太阳标记

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

#为这个主机增加小太阳标记

define host{

        use                   linux-server,host-pnp

        host_name        localhost

        alias                  localhost

        address             127.0.0.1

        }

#重新加载配置文件

service nagios reload

如果正确此时就会生成pnp文件

[root@localhost ~]# ls /usr/local/nagios/share/perfdata/localhost/

Current_Load.rrd   Current_Users.xml  PING.rrd            Root_Partition.xml

Current_Load.xml   HTTP.rrd           PING.xml            Swap_Usage.rrd

Current_Users.rrd  HTTP.xml           Root_Partition.rrd  Swap_Usage.xml

打开网页http://localhost/nagios

点击小太阳就可以看到图表，同访问http://localhost/nagios/pnp

FAQ: 注意可能提示这个模块没有安装：

Time/HiRes.pm模块的安装：

①执行以下命令安装该模块。

#perl -MCPAN -e 'install Time::HiRes'

或安装Time-HiRes-1.9707.tar.gz

②如果打开pnp页面提示Hostname is not set,则检查etc/pnp/里的sample文件都更改正确，检查templates.cfg文件中url的正确性，还不行就等等，别太心急了，装完没那么快出图。
