Nagios图形化Pnp 安装和配置 ZT(1)

Nagios图形化Pnp 安装和配置 ZT 具体过程如下：

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

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

register 0

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

process_perf_data 1

}

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

define command{

command_name process-service-perfdata

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

}

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
