nagios配置方法总结
一: 安装完nagios后在 /usr/local/nagios/etc/objects/中定义 要监控的文件 （监控主机）
[root@nagios-Server objects]# ls
commands.cfg  localhost.cfg  switch.cfg     test-001.cfg  timeperiods.cfg  |  这里的test.cfg ,test-001.cfg 是 配置文件对应的
contacts.cfg  printer.cfg    templates.cfg  test.cfg      windows.cfg      |   主机Nagios-client01  与 Nagios-client02

[root@nagios-Server objects]#
----------------------------------------
第二 配置服务器端的command.cfg 该文件在 /usr/local/nagios/etc/objects/中
在这个文件中主要添加 nrpe command ，其次这个实例中没有添加对swap的监控，我们手动加入swap的监控参数。
[root@nagios-Server objects]# cat commands.cfg
配置完成后运行
[root@nagios-Server objects]# cat commands.cfg

# COMMANDS.CFG - SAMPLE COMMAND DEFINITIONS FOR NAGIOS 3.2.0
#
# Last Modified: 05-31-2007
#
# NOTES: This config file provides you with some example command definitions
#        that you can reference in host, service, and contact definitions.
#      
#        You don't need to keep commands in a separate file from your other
#        object definitions.  This has been done just to make things easier to
#        understand.

###############################################################################

################################################################################
#
# SAMPLE NOTIFICATION COMMANDS
#
# These are some example notification commands.  They may or may not work on
# your system without modification.  As an example, some systems will require

总结：在服务器端主要配置两个文件 一：/usr/local/nagios/etc/objects/ 中的 要监控的主机  二：在/usr/local/etc/objects/command.cfg 文件中，添加如nrpe， swap 命令的支持
还有一个nrpe文件的配置，后面将会讲到。
------------------------------------------------------------------------------------------------------
配置被监控端
在被监控端安装 nagios-plugin ，nrpe后 在/usr/local/nagios/etc/ 中会有nrpe.cfg 这个文件
这个文件要做好，相关配置，信息如下：
有三个地方要注意
1 "server_address=0.0.0.0"
2 "allowed_hosts=127.0.0.1,192.168.40.30,192.168.40.40,192.168.40.50"
3 "command[check_hda3]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda3"
   "command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10% "
后来添加的监控对象在这里要做策略
[root@nagios-client01 nagios]# cat /usr/local/nagios/etc/nrpe.cfg
#############################################################################
# Sample NRPE Config File
# Written by: Ethan Galstad (nagios@nagios.org)
#
# Last Modified: 11-23-2007
#
# NOTES:
# This is a sample configuration file for the NRPE daemon.  It needs to be
# located on the remote host that is running the NRPE daemon, not the host
# from which the check_nrpe client is being executed.
#############################################################################

# LOG FACILITY
# The syslog facility that should be used for logging purposes.
log_facility=daemon

# PID FILE
# The name of the file in which the NRPE daemon should write it's process ID
# number.  The file is only written if the NRPE daemon is started by the root
# user and is running in standalone mode.
pid_file=/var/run/nrpe.pid

# PORT NUMBER
# Port number we should wait for connections on.
# NOTE: This must be a non-priviledged port (i.e. > 1024).
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
server_port=5666

# SERVER ADDRESS
# Address that nrpe should bind to in case there are more than one interface
# and you do not want nrpe to bind on all interfaces.
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
server_address=0.0.0.0

# NRPE USER
# This determines the effective user that the NRPE daemon should run as.  
# You can either supply a username or a UID.
#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
nrpe_user=nagios

# NRPE GROUP
# This determines the effective group that the NRPE daemon should run as.  
# You can either supply a group name or a GID.
#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
nrpe_group=nagios

# ALLOWED HOST ADDRESSES
# This is an optional comma-delimited list of IP address or hostnames
# that are allowed to talk to the NRPE daemon.
#
# Note: The daemon only does rudimentary checking of the client's IP
# address.  I would highly recommend adding entries in your /etc/hosts.allow
# file to allow only the specified host to connect to the port
# you are running this daemon on.
#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
allowed_hosts=127.0.0.1,192.168.40.30,192.168.40.40,192.168.40.50


# COMMAND ARGUMENT PROCESSING
# This option determines whether or not the NRPE daemon will allow clients
# to specify arguments to commands that are executed.  This option only works
# if the daemon was configured with the --enable-command-args configure script
# option.  
#
# *** ENABLING THIS OPTION IS A SECURITY RISK! ***
# Read the SECURITY file for information on some of the security implications
# of enabling this variable.
#
# Values: 0=do not allow arguments, 1=allow command arguments
dont_blame_nrpe=0

# COMMAND PREFIX
# This option allows you to prefix all commands with a user-defined string.
# A space is automatically added between the specified prefix string and the
# command line from the command definition.
#
# *** THIS EXAMPLE MAY POSE A POTENTIAL SECURITY RISK, SO USE WITH CAUTION! ***
# Usage scenario:
# Execute restricted commmands using sudo.  For this to work, you need to add
# the nagios user to your /etc/sudoers.  An example entry for alllowing
# execution of the plugins from might be:
#
# nagios          ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
#
# This lets the nagios user run all commands in that directory (and only them)
# without asking for a password.  If you do this, make sure you don't give
# random users write access to that directory or its contents!
# command_prefix=/usr/bin/sudo

# DEBUGGING OPTION
# This option determines whether or not debugging messages are logged to the
# syslog facility.
# Values: 0=debugging off, 1=debugging on
debug=0

# COMMAND TIMEOUT
# This specifies the maximum number of seconds that the NRPE daemon will
# allow plugins to finish executing before killing them off.
command_timeout=60

# CONNECTION TIMEOUT
# This specifies the maximum number of seconds that the NRPE daemon will
# wait for a connection to be established before exiting. This is sometimes
# seen where a network problem stops the SSL being established even though
# all network sessions are connected. This causes the nrpe daemons to
# accumulate, eating system resources. Do not set this too low.
connection_timeout=300

# WEEK RANDOM SEED OPTION
# This directive allows you to use SSL even if your system does not have
# a /dev/random or /dev/urandom (on purpose or because the necessary patches
# were not applied). The random number generator will be seeded from a file
# which is either a file pointed to by the environment valiable $RANDFILE
# or $HOME/.rnd. If neither exists, the pseudo random number generator will
# be initialized and a warning will be issued.
# Values: 0=only seed from /dev/random, 1=also seed from weak randomness
#allow_weak_random_seed=1

# INCLUDE CONFIG FILE
# This directive allows you to include definitions from an external config file.
#include=

# INCLUDE CONFIG DIRECTORY
# This directive allows you to include definitions from config files (with a
# .cfg extension) in one or more directories (with recursion).
#include_dir=
#include_dir=

# COMMAND DEFINITIONS
# Command definitions that this daemon will run.  Definitions
# are in the following format:
#
# command[]=
#
# When the daemon receives a request to return the results of
# it will execute the command specified by the  argument.
#
# Unlike Nagios, the command line cannot contain macros - it must be
# typed exactly as it should be executed.
#
# Note: Any plugins that are used in the command lines must reside
# on the machine that this daemon is running on!  The examples below
# assume that you have plugins installed in a /usr/local/nagios/libexec
# directory.  Also note that you will have to modify the definitions below
# to match the argument format the plugins expect.  Remember, these are
# examples only!

# The following examples use hardcoded command arguments...
command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
command[check_hda3]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda3
command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%
# The following examples allow user-supplied arguments and can
# only be used if the NRPE daemon was compiled with support for
# command arguments *AND* the dont_blame_nrpe directive in this
# config file is set to '1'.  This poses a potential security risk, so

总结：文件配置的顺序 （当然这个不是死的可以灵活来的，针对我自己而言）首先配置服务器端的
1 /usr/local/nagios/etc/objects/中创建  要检测的主机 其实就是写一个文件
2 /usr/local/nagios/etc/ 中修改 nagios.cfg ，主要做的就是 添加 要检测的主机 及第一步中设置的文件 比如 ：
# You can specify individual object config files as shown below:
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
cfg_file=/usr/local/nagios/etc/objects/test.cfg     ---------这个文件就是在第一步中建立的东西 要检测的主机
cfg_file=/usr/local/nagios/etc/objects/test-001.cfg ---------还有这个也是
# Definitions for monitoring the local (Linux) host
#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
3 /usr/local/nagios/etc/commands.cfg 文件中添加相关命令，这里我是用的nrpe，还有一个swap的命令，看如上的配置中会有。
“说明下 在服务器端 要安装的 有 nagios 主程序，nagios-plgins ，nrpe 好了继续”
4 现在配置 “被监控端” 在被监控端 要安装 nagios-plgins，nrpe 后 会有 /usr/local/nagios/ 这个目录
定义nrpe.cfg
在被监控端  要配置好 在监控端 要监控的东西，比如我们添加了对 swap ，hda1 ,hda3
在nrpe.cfg中要定义好（/usr/local/nagios/etc/nrpe.cfg）
在这个文件中要修改的地方有3个 一是 “server_address” 二是 “allowed_hosts” 第三 后添加的 监控对象 看如上的配置中会有。
“command[check_hda3]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda3”
“command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10% ”
修改完后 重启下nrpe
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg
