Nagios監(jiān)控服務(wù)器的配置
圖-Nagios
Nagios監(jiān)控服務(wù)器的配置如下：
1.安裝nrpe
[root@UnixHot src]# tar zxvf nrpe-2.12.tar.gz
[root@UnixHot nrpe-2.12]# ./configure && make all
[root@UnixHot nrpe-2.12]# make install-plugin
[root@UnixHot nrpe-2.12]# make install-daemon
[root@UnixHot nrpe-2.12]# make install-daemon-config
[root@UnixHot nrpe-2.12]# make install-xinetd
2.配置nrep
[root@UnixHot nrpe-2.12]# vi /etc/xinetd.d/nrpe
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
disable = no
only_from = 127.0.0.1 192.168.0.206 192.168.0.155 192.168.0.157
在only_from 添加要監(jiān)控的主機的IP地址，中間以空格隔開。
#p#
3.添加端口
[root@UnixHot nrpe-2.12]# vi /etc/services 在***添加
nrpe 5666/tcp #nrpe
4.重新啟動Xinetd服務(wù)
[root@UnixHot nrpe-2.12]# /etc/init.d/xinetd restart
[root@UnixHot nrpe-2.12]# netstat -na | grep 5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN
以上的1-4的步驟要在客戶端上做。
5.修改配置文件commands.cfg加入對nrpe的支持
[root@UnixHot ~]# vi /usr/local/nagios/etc/objects/commands.cfg
#nrpe set
define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
#p#
6.有哪些nrpe檢測命令可以用，它們在哪里呢?
[root@UnixHot ~]# vi /usr/local/nagios/etc/nrpe.cfg
(默認(rèn)有下面四個命令)
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
7.怎么使用這些命令監(jiān)控客戶端呢?
其實很簡單，就是在services.cfg里面添加服務(wù)即可，格式就和上篇文檔講的一樣，只是命令不同罷了。
[root@UnixHot ~]# vi /usr/local/nagios/etc/objects/services.cfg
加入：
define service {
host_name Nagios-Server
service_description check-users
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,u,c,r
check_command check_nrpe!check_users
}
define service {
host_name Nagios-Server
service_description check-load
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,u,c,r
check_command check_nrpe!check_load
}
define service {
host_name Nagios-Server
service_description check-total-procs
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,u,c,r
check_command check_total_procs
}
在這里僅列出了一個客戶端的配置，其它的客戶端，只需修改host_name 即可。
通過這篇文章的介紹，我們清楚的知道Nagios監(jiān)控服務(wù)器的配置情況！
