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)   

 

 

 

[[email protected] 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)

 

[[email protected] 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[email protected]

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 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

 

[[email protected] libexec]# ./check_users -h (每个插件都会提供帮助)

拒绝连接

[[email protected] libexec]# ./check_tcp -H 192.168.4.254 -p 22

TCP OK - 0.000 second response time on port 22|time=0.000243s;;;0.000000;10.000000

 

 

 

____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)_____________________

 

[[email protected] 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?

 

[[email protected] nagios]#  /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg   (检查配置文件是否有错)

 

[[email protected] 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)

[[email protected] ~]# 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

[[email protected] nagios]# /etc/init.d/postfix status

master (pid  1766) 正在运行...

 

[[email protected] ~]# 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

[[email protected] ~]# 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

[[email protected] ~]# 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)

[[email protected] ~]# 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.

        host_name               localhost

        alias                   localhost

        address                 127.0.0.1

        }

 

define service{

        use                             local-service         ; Name of service template to use

        host_name                       localhost

        service_description             PING

check_commandcheck_ping!100.0,20%!500.0,60%

        }

        }

 

[[email protected] 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

[[email protected] nagios]# cd /usr/local/nagios/sbin/

[[email protected] sbin]# ls

avail.cgi   extinfo.cgi        outages.cgi  statuswml.cgi  tac.cgi

#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
