2.监控服务端2的资源及测试

A）在服务端2安装net-snmp及配置

[[email protected] ~]# yum install net-snmp* -y           #安装

[[email protected] ~]# cd /etc/snmp/

[[email protected] snmp]# vim snmpd.conf                  #进入配置文件

 40 #       sec.name source          community

 41 #com2secnotConfigUser  default       public

 42 com2sec local     localhost           wen       #添加本地资源，名字任意（wen）

 43 com2sec mynetwork172.25.25.0/24      wen       #允许25网段的监控

 49 #group   notConfigGroup v1           notConfigUser

 56 group MyROGroupusm        mynetwork

 62 view    systemview    included  .1.3.6.1.2.1

 63 view    systemview    included  .1.3.6.1.2.1.25.1.1

 64 view all    included .1                              80

 69 #access  notConfigGroup ""      any      noauth    exact  systemview none none

331 disk / 10000                                   #允许监控磁盘

[[email protected] snmp]# /etc/init.d/snmpd start         #开启

Starting snmpd:                                           [  OK  ]

[[email protected] snmp]# snmpwalk -v 1 -c wen localhostIP-MIB::ipAdEntIfIndex   #测试数据，正常

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.172.25.25.2 = INTEGER: 2

在服务端1测试，正常

[[email protected] ~]$ snmpwalk -v 1 -c wen 172.25.25.2IP-MIB::ipAdEntIfIndex   

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.172.25.25.2 = INTEGER: 2

[[email protected] ~]$ snmpwalk -v 1 -c wen 172.25.25.2.1.3.6.1.4.1.2021.9

UCD-SNMP-MIB::dskIndex.1 = INTEGER: 1

UCD-SNMP-MIB::dskPath.1 = STRING: /

UCD-SNMP-MIB::dskDevice.1 = STRING:/dev/mapper/VolGroup-lv_root

UCD-SNMP-MIB::dskUsedHigh.1 = Gauge32: 0

UCD-SNMP-MIB::dskErrorFlag.1 = INTEGER: noError(0)

UCD-SNMP-MIB::dskErrorMsg.1 = STRING:

B）在图形界面添加设备及测试

选择add添加设备

依次填写设备名、ip、类型；将默认的public改写成文件里添加的名字（wen）选择create

选择create之后，如下图，点击Create Graphs for this Host

如下图选择，点击create，设备添加成功

点击Graph Trees之后，如图，点击Default Trees

如图，点击Add

在Tree ltem Type中选择Host Host中选择server2 Round Robin Archive中选择5 Minute，点击create

C）测试  点击graphs

等5分钟后刷新，如图：

 

3.cacti支持多线程的配置

A）安装配置cacti-spine

[[email protected] mnt]# yum install -y net-snmp-devel mysql-developenssl-devel dos2unix autoconf binutils libtool gcc cpp glibc-headerskernel-headers gilbc-devel   #安装安装cacti-spine之前所需要的包

[[email protected] mnt]# ls

cacti-0.8.8h.tar.gz cacti-spine-0.8.8h.tar.gz

php-snmp-5.3.3-26.el6.x86_64.rpm

[[email protected] mnt]# tar zxf cacti-spine-0.8.8h.tar.gz

[[email protected] mnt]# cd cacti-spine-0.8.8h

[[email protected] cacti-spine-0.8.8h]# sh bootstrap              #检查编译环境

[[email protected] cacti-spine-0.8.8h]# ./configure

[[email protected] cacti-spine-0.8.8h]# make

[[email protected] cacti-spine-0.8.8h]# make install

[[email protected] cacti-spine-0.8.8h]# cd /usr/local/spine/

[[email protected] spine]# ls

bin  etc

[[email protected] spine]# cd etc/

[[email protected] etc]# cp spine.conf.dist /etc/spine.conf      #配置文件

[[email protected] bin]# vim /etc/spine.conf

 33 DB_Host         localhost                              #本地数据库

 34 DB_Database     cacti                                  #数据库的名字

 35 DB_User         cacti                                  #数据库的用户

 36 DB_Pass         redhat                                 #密码

 37 DB_Port         3306                                   #端口

[[email protected] etc]# cd ..

[[email protected] spine]# cd bin/                                  

[[email protected] bin]# ls                                      #启动脚本

spine

[[email protected] bin]# pwd

/usr/local/spine/bin

[[email protected] bin]# su - cacti

[[email protected] ~]$ /usr/local/spine/bin/spine           #测试脚本，正常

SPINE: Using spine config file [/etc/spine.conf]

SPINE: Version 0.8.8h starting

SPINE: Time: 0.0820 s, Threads: 5, Hosts: 3

B）在图形界面添加脚本路径及更改poller的类型

点击Setting中的Paths添加启动sping脚本的路径

将cmd.php换成spine就可以支持多线程了。（线程设置在Devices中将Host Template）

 

4.用命令行设置监控及测试

A）用命令行设置监控

[[email protected] mnt]# uptime | awk ‘{print$1,$(NF-2),$(NF-1),$(NF)}‘ | sed ‘s/,//g‘

15:16:15 0.00 0.00 0.00

[[email protected] mnt]# uptime | awk ‘{print$1,$(NF-2),$(NF-1),$(NF)}‘ | sed ‘s/,//g‘ >>/tmp/uptime

[[email protected] mnt]# cat /tmp/uptime

15:16:59 0.00 0.00 0.00

[[email protected] mnt]# vim /mnt/uptime.sh              #写脚本

#!/bin/bash
 
#create by 2016
 
uptime | awk ‘{print $1,$(NF-2),$(NF-1),$(NF)}‘ | sed ‘s/,//g‘>>/tmp/uptime

[[email protected] mnt]# chmod +x /mnt/uptime.sh          #给执行权限

[[email protected] mnt]# crontab –e                     #创建定时任务（每隔10秒钟执行一次/mnt/uptime.sh脚本）

* * * * * /mnt/uptime.sh

* * * * * sleep 10;/mnt/uptime.sh

* * * * * sleep 20;/mnt/uptime.sh

* * * * * sleep 30;/mnt/uptime.sh

* * * * * sleep 40;/mnt/uptime.sh

* * * * * sleep 50;/mnt/uptime.sh

[[email protected] mnt]# dd if=/dev/zero of=/dev/null &   #加负载，制造峰值

[1] 7811

[[email protected] mnt]# cat /tmp/uptime                  #查看，在增加

15:16:59 0.00 0.00 0.00

15:21:01 0.00 0.00 0.00

[[email protected] mnt]# kill -9 dd                  #去掉负载

[[email protected] bin]# yum install -y gnuplot       #安装绘图工具

[[email protected] html]# vim /mnt/uptime.sh         #继续编辑脚本

 #!/bin/bash
 
#create by 2016
 
uptime | awk ‘{print $1,$(NF-2),$(NF-1),$(NF)}‘ | sed ‘s/,//g‘>>/tmp/uptime
