nagios之pnp

1.安裝rrdool

安裝所需環境：yum  install gcc libxml2-devel libpng-devel pkg-config glib pixman pango pango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel libart_lgpl-devel

2.下載安裝包

wget  http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz

# tar zxvf rrdtool-1.4.5.tar.gz  

# cd rrdtool-1.4.5

# ./configure --prefix=/usr/local/rrdtool

# make

# make install

在安裝過程中，出現 

configure: error: Please fix the library issues listed above and try again錯誤 

(1)安裝 cgilib-0.5.tar.gz    

#wget http://download.chinaunix.net/down.php?id=2531&ResourceID=1333&site=1  

#tar zxvf cgilib-0.5.tar.gz  

#cd cgilib-0.5  

#make  

#cp libcgi.a /usr/local/lib  

#cp cgi.h /usr/include  

(2)安裝libart_lgpl-devel這個包  

#yum –y install libart_lgpl-devel  

(3)如果還報錯,把這兩個包裝上pango-devel cairo-devel  

# yum –y install pango-devel* cairo-devel*    

#cd cd rrdtool-X.X.X  

#./configure --prefix=/usr/local/rrdtool   

(4)如果還是不行的話，試試yum install libxml2-devel  

重新make可以先make clean

3.如何驗證是否安裝成功

[root@localhost bin]# /usr/local/rrdtool/bin/rrdtool

pnp安裝

1.安裝pnp

wget http://nchc.dl.sourceforge.net/project/pnp4nagios/PNP/pnp-0.4.14/pnp-0.4.14.tar.gz

configure: WARNING: Perl Module RRDs not available

 General Options:

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

  Nagios user/group:                nagios nagios

  Install directory:                /usr/local/pnp4nagios

type 'make all' to compile.

解決方法

#cd /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi

#cp RRDs.pm /usr/lib/perl5/5.8.8/i386-linux-thread-multi/

#cp /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/auto/RRDs/RRDs.so /usr/lib/perl5/5.8.8/i386-linux-thread-multi/

重新./configure

[root@localhost pnp4nagios-0.6.20]#./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group-nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata --with-perl_lib_path=/usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/

3.安裝完成，PNP默認文件放置情況如下：

*** Configuration summary for pnp 0.4.14 05-02-2009 ***

 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

  Location of rrdtool binary:       /usr/local/rrdtool/bin/rrdtool Version 1.4.7

  RRDs Perl Modules:                FOUND (Version 1.4007)

  RRDs Perl search path:            /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/

  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/

4.設置PNP

① 創建默認配置文件

cd  /usr/local/nagios/etc/pnp

cp process_perfdata.cfg-sample process_perfdata.cfg 此文件無sample文件，將源文件備份即可

cp npcd.cfg-sample npcd.cfg

cp rra.cfg-sample rra.cfg

[root@localhost pnp]# chown -R nagios:nagios /usr/local/pnp4nagios/etc/

② 修改process_perfdata.cfg文件

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

這里將日志級別改為2,即為debug模式。

5.修改nagios配置文件

①增加小太陽標示

修改templates.cfg，增加一個定義PNP的hosts和services

define host {

        name       hosts-pnp

        register   0

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

        process_perf_data               1

}

define service {

        name       services-pnp

        register   0

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

        process_perf_data               1

}

②修改nagios.cfg

找到如下幾項，去掉注釋，修改后信息如下：

process_performance_data=1

host_perfdata_command=process-host-perfdata

service_perfdata_command=process-service-perfdata

③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

define command{

        command_name    process-service-perfdata

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

}

④修改hosts.cfg文件和services.cfg文件

define host{

        use                     linux-server,hosts-pnp

        host_name               web

        alias                   ixdba-web

        address                 192.168.12.251

        }

define host{

        use                     linux-server,hosts-pnp

        host_name               mysql

        alias                   ixdba-mysql

        address                 192.168.12.237

        }

define service{

        use                             local-service,services-pnp

        host_name                       mysql

        service_description             SSH

        check_command                   check_ssh

        }

define service{

        use                             local-service,services-pnp

        host_name                       web

        service_description             http

        check_command                   check_http

        }

6.測試PNP功能

所有配置完成之后，重新檢查nagios配置文件是否正確，然后重啟nagios

/etc/init.d/nagios restart

如果配置正確，此時就會生成響應主機的pnp文件

[root@nagios web]# pwd

/usr/local/nagios/share/perfdata/web

[root@gaojf web]# ls

http.rrd  http.xml  PING.rrd  PING.xml  SSHD.rrd  SSHD.xml

最后打開網頁：

打開網頁http://IP/nagios，選擇主機選項，然后點擊小太陽就可以看到圖表，或者訪問http://ip/nagios/pnp也可以直接訪問圖表信息。

進入監控界面，點擊監控主機的小太陽提示一下錯誤

PHP zlib Support not found.

PHP GD Support not found.

（1）由于編譯PHP時候未將zlib,gd編譯進PHP中，需要重新編譯PHP 添加參數--with-zlib,--with-gd

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-zlib --with-gd

（2）安裝完PHP提示

You may want to add: /usr/local/php/lib/php to your php.ini include_path

/root/rpm/php-5.3.23/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin

ln -s -f /usr/local/php/bin/phar.phar /usr/local/php/bin/phar
