Nagios圖形化Pnp 安裝和配置

⑴安裝完nagios，繼續安裝pnp，要注意rrdtool的安裝。

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 安裝在 /usr/local/nagios/share/

配置示例檔案安裝在/usr/local/nagios/libexecs

config.php安裝于/usr/local/nagios/etc/pnp

<a></a>

⑵修改配置檔案

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

#先改為2,為debug模式

③

修改etc/objects/templates.cfg增加新指令（增加小太陽标記）

#在use的後面添加"host-pnp"即可讓監控圖上的主機名稱旁邊增加一個小太陽的标記，點選此标記即可檢視pnp圖檔。

define host {

        name       host-pnp

        register   0

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

        process_perf_data               1

}

#還可以在service欄添加srv-pnp，添加後會在相應的欄内增加小太陽。

define service {

        name       srv-pnp

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

④

修改etc/nagios.cfg

找到如下幾項，去掉注釋

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下的安全問題,需作如下配置

修改pnp的web伺服器配置檔案nginx.conf,請注意安全問題，我這裡未做安全驗證。

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;

     }

如果開啟了open_basedir還需修改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測試：

為localhost這台主機在主機圖示旁邊添加個小太陽标記

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

#為這個主機增加小太陽标記

define host{

        use                   linux-server,host-pnp

        host_name        localhost

        alias                  localhost

        address             127.0.0.1

        }

#重新加載配置檔案

service nagios reload

如果正确此時就會生成pnp檔案

[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

打開網頁http://localhost/nagios

點選小太陽就可以看到圖表，同通路http://localhost/nagios/pnp

FAQ: 注意可能提示這個子產品沒有安裝：

Time/HiRes.pm子產品的安裝：

①執行以下指令安裝該子產品。

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

或安裝Time-HiRes-1.9707.tar.gz

②如果打開pnp頁面提示Hostname is not set,則檢查etc/pnp/裡的sample檔案都更改正确，檢查templates.cfg檔案中url的正确性，還不行就等等，别太心急了，裝完沒那麼快出圖。
