Nagios圖形化Pnp 安裝和配置 ZT
Nagios圖形化Pnp 安裝和配置 ZT 具體過(guò)程如下：
⑴安裝完nagios，繼續(xù)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/
配置示例文件安裝在/usr/local/nagios/libexecs
config.php安裝于/usr/local/nagios/etc/pnp
⑵修改配置文件
?、?/p>
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 *
?、?/p>
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增加新命令(增加小太陽(yáng)標(biāo)記)
#在use的后面添加"host-pnp"即可讓監(jiān)控圖上的主機(jī)名稱(chēng)旁邊增加一個(gè)小太陽(yáng)的標(biāo)記，點(diǎn)擊此標(biāo)記即可查看pnp圖片。
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，添加后會(huì)在相應(yīng)的欄內(nèi)增加小太陽(yáng)。
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
找到如下幾項(xiàng)，去掉注釋
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
?、?/p>
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
}
?、辬ginx下的安全問(wèn)題,需作如下配置
修改pnp的web服務(wù)器配置文件nginx.conf,請(qǐng)注意安全問(wèn)題，我這里未做安全驗(yàn)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(kāi)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
#p#
?、鐪y(cè)試：
為localhost這臺(tái)主機(jī)在主機(jī)圖標(biāo)旁邊添加個(gè)小太陽(yáng)標(biāo)記
vi /usr/local/nagios/etc/nagios.cfg
#為這個(gè)主機(jī)增加小太陽(yáng)標(biāo)記
define host{
use linux-server,host-pnp
host_name localhost
alias localhost
address 127.0.0.1
}
#重新加載配置文件
service nagios reload
如果正確此時(shí)就會(huì)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
打開(kāi)網(wǎng)頁(yè)http://localhost/nagios
點(diǎn)擊小太陽(yáng)就可以看到圖表，同訪問(wèn)http://localhost/nagios/pnp
FAQ: 注意可能提示這個(gè)模塊沒(méi)有安裝：
Time/HiRes.pm模塊的安裝：
?、賵?zhí)行以下命令安裝該模塊。
#perl -MCPAN -e 'install Time::HiRes'
或安裝Time-HiRes-1.9707.tar.gz
②如果打開(kāi)pnp頁(yè)面提示Hostname is not set,則檢查etc/pnp/里的sample文件都更改正確，檢查templates.cfg文件中url的正確性，還不行就等等，別太心急了，裝完沒(méi)那么快出圖。
仔細(xì)的把文章閱讀后，我們掌握了Nagios圖形化Pnp 安裝和配置 ZT 。
