Linux监控
Nagios
1 什么是监控? 监视控制
2 监控谁? 各种服务器
3 监控什么? 网络流量(eth0,eth1) 服务的状态(运行,停止) 硬件资源 cpu 内存 存储
系统运行情况(总数,运行,休眠,僵尸)
[root@room1pc01 桌面]# uptime
09:15:02 up 15min, 4 users, load average: 0.01, 0.10, 0.08
(数越大,说明在线时间越长,越好)
[root@room1pc01 桌面]# top (看cpu)
4 如何监控? 使用命令 编写脚本 监控软件
自动监控:
计划任务+监控脚本 (chkconfig crond on)
搭建监控服务器(软件 Nagios Cacti Zabbix)
5如何接收报警信息(邮件,短信,微信,即时消息)
++++++++++++++++++++++++++++++++
配置监控服务器的步骤:
1. 部署服务运行环境 httpd(nginx或Apache,php) yum -y install httpd php
2. 安装提供服务的软件
2.1 安装准备
2.2 安装监控服务软件 和 监控插件软件
2.3 修改服务配置文件
2.4 启动监控服务
3. 配置监控服务
3.1 配置监控远端服务器
3.2 配置监控自己(特殊情况,公司小只有一个网站服务器时,网站和监控服务配在一台上,所以监控本机网站)
不监控本机的交换分区
监控引导分区的使用情况
监控ftp的运行状态
指定接收报警信息的邮箱地址是nagios@localhost
4 配置监控报警
5 查看监控信息
设置查看访问监控页面的认证用户名和密码(不能随便指) nagiosadmin
nagios服务的监控过程:服务运行时调用插件,调用插件时,可以设置插件监控的阀值,nagios服务把监控到的值和插件指定的值比较,根据比较结果显示监控状态》
插件监控的阀值种类:警告值 错误值(值的多少由运维人员指定)
监控状态: ok正常 warning警告状态 critical 严重错误 unknow配置错误 pending正在监控
监控到的数据小于警告值 显ok 大于 警告值且小于错误值显示warning 大于错误值 显示critical
nagios服务默认监控本机哪些资源?
cpu负载
登录系统总用户数
网站服务运行状态
主机是否在线
跟分区使用量
sshd服务运行状态
[root@99 libexec]# ./check_users -h (每个插件都会提供帮助)

____修改服务配置文件可以自己增加监控服务 (先增加监控本机服务)_____________________
[root@99 nagios-3.2.1]# ls /usr/local/nagios
bin etc libexec sbin share var
libexec:插件目录
bin:可执行命令
etc:配置文件
sbin:cgi文件(点监控页面时出现的各种页面)
var:变化的,日志 缓存
share:配置文件
nagios服务配置文件说明?
[root@99 nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg (检查配置文件是否有错)
[root@99 nagios]# vim /usr/local/nagios/etc/nagios.cfg
19 log_file=/usr/local/nagios/var/nagios.log
30 cfg_file=/usr/local/nagios/etc/objects/commands.cfg (设置服务运行时使用的监控插件)
31 cfg_file=/usr/local/nagios/etc/objects/contacts.cfg (设置接收报警消息的邮箱地址)
32 cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg (定义监控时间模板的文件—)
33 cfg_file=/usr/local/nagios/etc/objects/templates.cfg (定义监控模板的配置文件)
36 cfg_file=/usr/local/nagios/etc/objects/localhost.cfg (这个文件监控本机的配置文件,是里面的内容容器导致,不是文件名可以随变)
/usr/local/nagios/etc/resource.cfg 宏定义 $USER1$(插件定义目录)
_______________________
1)
[root@99 ~]# vim /usr/local/nagios/etc/objects/commands.cfg (设置增加监控服务使用的插件)
define command {
command_name monitor_localhost_boot
command_line /usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /boot
} (这四行和下面四行只要写一个就行。这用的是常量,下面变量)
define command {
command_name monitor_localhost_boot
command_line /usr/local/nagios/libexec/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$
}
define command {
command_name monitor_localhost_ftp
comman_line $USER1$/check_ftp -H localhost -p 21
}
2)设置接收报警消息的邮箱地址
[root@99 nagios]# /etc/init.d/postfix status
master (pid 1766) 正在运行...
[root@99 ~]# vim /usr/local/nagios/etc/objects/contacts.cfg (设置接收报警消息的邮箱地址,先邮件服务开启,如果设置的是163,一定要先能163能接收到)
3)定义监控时间模板的文件
[root@99 ~]# vim /usr/local/nagios/etc/objects/timeperiods.cfg
28 define timeperiod{
29 timeperiod_name 24x7
30 alias 24 Hours A Day, 7 Days A Week
31 sunday 00:00-24:00
32 monday 00:00-24:00
33 tuesday 00:00-24:00
34 wednesday 00:00-24:00
35 thursday 00:00-24:00
36 friday 00:00-24:00
37 saturday 00:00-24:00
38 }
39
40
41 # ‘workhours‘ timeperiod definition
42 define timeperiod{
43 timeperiod_name workhours
44 alias Normal Work Hours
45 monday 09:00-17:00
46 tuesday 09:00-17:00
47 wednesday 09:00-17:00
48 thursday 09:00-17:00
49 friday 09:00-17:00
50 }
4)定义监控模板的配置文件
[root@99 ~]# vim /usr/local/nagios/etc/objects/templates.cfg
5)(这个文件监控本机的配置文件,是里面的内容容器导致,不是文件名,文件名可以随变起)把增加的监控本机的服务写在监控本机配置文件中(在底下写)
[root@99 ~]# vim /usr/local/nagios/etc/objects/localhost.cfg
define host{
use linux-server ; Name of host template to use
; This host definition will inherit all variables that are defined
; in (or inherited by) the linux-server host template definition.

}
define service{

[root@99 nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 测试配置文件语法是否有错
6)设置访问cgi配置用户
[root@99 nagios]# cd /usr/local/nagios/sbin/
[root@99 sbin]# ls

监控远端主机的私有数据(磁盘 进程 用户)
总数,运行,休眠,僵尸
1 在被监控的主机上安装 监控插件 (192.168.4.98)
#yum -y install gcc gcc-c++
250 tar -zxvf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
257 ./configure
258 make
259 make install
262 ls /usr/local/nagios/libexec/
[root@stu ~]# /usr/local/nagios/libexec/check_users -w 3 -c 5
USERS OK - 2 users currently logged in |users=2;3;5;0
[root@stu ~]#/usr/local/nagios/libexec/check_procs -w 50 -c 60 -s Z
PROCS OK: 0 processes with STATE = Z
[root@stu ~]# /usr/local/nagios/libexec/check_procs -w 50 -c 60 -s R
PROCS OK: 0 processes with STATE = R
[root@stu ~]# /usr/local/nagios/libexec/check_procs -w 50 -c 60 (总进程)

DISK OK - free space: / 42137 MB (92% inode=97%);| /=3215MB;23893;33450;0;47786
2 在被监控的主机上运行nrpe服务
#useradd nagios
#rpm -q openssl openssl-devel
#tar -zxvf nrpe-2.12.tar.gz
#cd nrpe-2.12
#./configure
#make all
#make install-plugin
#make install-daemon
#make install-daemon-config
#make install-xinetd
#vim /etc/xinetd.d/nrpe
only_from = 127.0.0.1 172.40.50.99
:wq
#vim /etc/services
nrpe 5666/tcp# NRPE
:wq
#yum -y install xinetd
#service xinetd start
# chkconfig xinetd on
#netstat -utnalp | grep :5666
3.改nrpe服务的主配置文件,设置获取本地的私有数据(192.168.4.98)
vim /usr/local/nagios/etc/nrpe.cfg
#command[命令名]=本机使用的插件
199 command[check_nrpe_users]=/usr/local/nagios/libexec/check_users -w 2 -c 5
200 command[check_nrpe_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
201 command[check_nrpe_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/vda1
202 command[check_nrpe_root]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
204 command[check_nrpe_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
205 command[check_nrpe_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
:wq
# /etc/init.d/xinetd restart
验证nrpe命令(192.168.4.98)
/usr/local/nagios/libexec/check_nrpe -H localhost -c check_nrpe_root
4.在监控服务器上配置(192.168.4.99)
#/usr/local/nagios/libexec/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_users (报错,没那个目录)
1)安装依赖包
# yum -y install openssl openssl-devel
2)
# tar -zxvf nrpe-2.12.tar.gz
# cd nrpe-2.12
#./configure
#make all
#make install-plugin
#ls /usr/local/nagios/libexec/check_nrpe
3)在命令行下测试
# /usr/local/nagios/libexec/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_users
USERS OK - 2 users currently logged in |users=2;2;5;0
# /usr/local/nagios/libexec/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_load
OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0;
4)把连接nrpe服务的插件定义成nagios服务可以使用的监控命令
# vim /usr/local/nagios/etc/objects/commands.cfg
...............................
define command {
command_name monitor_server98_boot
command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_boot
}
define command {
command_name monitor_server98_load
command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_load
}
define command {
command_name monitor_server98_users
command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_load
}
define command {
command_name monitor_server98_root
command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_root
}
define command {
command_name monitor_server98_zombie
command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_zombie_proc
}
define command {
command_name monitor_server98_total_procs
command_line $USER1$/check_nrpe -H 192.168.4.98 -p 5666 -c check_nrpe_total_procs
}
5)在监控主机配置文件中调用定义的监控命令
# vim /usr/local/nagios/etc/objects/otherser.cfg
#################################private###########################
define service{
use local-service
host_name server98
service_description users
check_command monitor_server98_users
}
define service{
use local-service
host_name server98
service_description root
check_command monitor_server98_root
}
define service{
use local-service
host_name server98
service_description total_procs
check_command monitor_server98_total_procs
}
define service{
use local-service
host_name server98
service_description boot
check_command monitor_server98_boot
}
define service{
use local-service
host_name server98
service_description load
check_command monitor_server98_load
}
define service{
use local-service
host_name server98
service_description zombie
check_command monitor_server98_zombie
}
6)测试配置文件是否有语法错误
# alias plj=‘/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg‘
# plj
7)重启监控服务
# /etc/init.d/nagios restart
8)查看监控信息
