 架構
http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf

nagios-4.0.2.tar.gz 是最主要的部分
nagios-plugins-1.5.tar.gz 提供 check_disk、check_load、、、等檢查程式，你也可以自己撰寫 (任何語言甚至 shell script 都可)
nrpe-2.14.tar.gz 提供受監控主機和監看畫面主機間溝通


預設帳號是 nagiosadmin
預設密碼是 password
如果想改密碼, 請找到

htpasswd  -cb  /usr/local/nagios/etc/htpasswd.users   nagiosadmin   password

把 password 換成你要的密碼

cd nagios-4.0.2
./configure --with-command-group=nagcmd
make all
make install
make install-init
make install-config
make install-commandmode

# 4) Customize Configuration

# vi /usr/local/nagios/etc/objects/contacts.cfg

#5) Configure the Web Interface

make install-webconf
#htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
# Set ID : nagiosadmin, Password : password
htpasswd -cb /usr/local/nagios/etc/htpasswd.users nagiosadmin password
service httpd restart
cd ..

#6) Compile and Install the Nagios Plugins

tar xzf nagios-plugins-1.5.tar.gz
cd nagios-plugins-1.5
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
cd ..

# 7) Start Nagios

chkconfig --add nagios
chkconfig nagios on
# check  /usr/local/nagios/etc/nagios.cfg
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
# reload nagios.cfg
service nagios start

#8) Modify SELinux Settings
# Fedora ships with SELinux (Security Enhanced Linux) installed and in Enforcing mode by default. This can result in "Internal Server Error" messages when you attempt to access the Nagios CGIs.
# See if SELinux is in Enforcing mode.
# getenforce
# Put SELinux into Permissive mode.
# setenforce 0
# To make this change permanent, you'll have to modify the settings in /etc/selinux/config and reboot.
# Instead of disabling SELinux or setting it to permissive mode, you can use the following command to run the CGIs under SELinux enforcing/targeted mode:
# chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/
# chcon -R -t httpd_sys_content_t /usr/local/nagios/share/
# For information on running the Nagios CGIs under Enforcing mode with a targeted policy, visit the NagiosCommunity.org wiki at http://www.nagioscommunity.org/wiki.

# 9) Login to the Web Interface

# You should now be able to access the Nagios web interface at the URL below. You'll be prompted for the username (nagiosadmin) and password you specified earlier.

#firefox http://localhost/nagios/ &

#如果你有自己做的設定檔案, 記得改變擁有者, 讓 nagios 可以讀取

    冒昧請問 怎麼實現Windows mount point volume 的空間監控?

    ./check_nrpe -u -H 192.168.102.71 -p 5666 -c CheckDriveSize -a ShowAll MaxWarnUsed=90% MaxCritUsed=95% Drive=C:/Volume/abc
    OK: C:/Volume/abc: Total: 16.568GB - Used: 120.719MB - Free: 16.45GB|'C:/Volume/abc used'=0GB;14;15;0;16 'C:/Volume/abc used %'=0%;89;94;0;100

    直接於command line執行沒問題，可是在Nagios內的的log則出現Could not get free space reason 3

    再麻煩指教一下，感恩

      不知道您發生甚麼問題，您是用 CentOS ? 用 root ?

      我是用Nagios去監控Windows，Windows內安裝NSclient++ 4.2.88
      實體硬碟C:、D:我知道可以利用check_nt的指令去檢查剩餘空間
      不過掛載的磁碟(C:\abc\Volume_1，C:\abc\Volume_2這類)就不知道怎麼處理了

      有查到可利用check_nrpe CheckDriveSize的方式
      不過我測試Nagios主機的終端機上透過指令執行都沒問題也可以正常回報
      但是上到Nagios上就會出現錯誤了

      刪除
