实验内容：

1.监控物理主机

2.Spine 多线程监控

3.monitor监控插件

  1.监控物理主机

        在物理主机上配置如下：
      <1>yum install net-snmp.x86_64 -y   ##安装snmp服务
       yum install net-snmp-utils.x86_64 -y
      <2>vim /etc/snmp/snmpd.conf

 41 #com2sec notConfigUser  default    public

 42 com2sec local   localhost      public

 43 com2sec mynetwork 172.25.254.0/24    public

 44

 45 ####

 46 # Second, map the security name into a group name:

 47

 48 #    groupName    securityModel securityName

 49 #group  notConfigGroup v1      notConfigUser

 50 #group  notConfigGroup v2c      notConfigUser

 51 group MyRWGroup v1     local

 52 group MyRWGroup v2c     local

 53 group MyRWGroup usm     local

 54 group MyROGroup v1     mynetwork

 55 group MyROGroup v2c     mynetwork

 56 group MyROGroup usm     mynetwork

 57 ####

 58 # Third, create a view for us to let the group have rights to:

 59

 60 # Make at least  snmpwalk -v 1 localhost -c public system fast again.

 61 #    name      incl/excl   subtree     mask(optional)

 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

 65 ####

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

 70 access MyROGroup ""    any    noauth   exact  all   none  none

 71 access MyRWGroup ""    any    noauth   exact  all   all   none

    <6>网页端配置
        打开网页http:172.25.254.10
        在左边选Device 然后点击Add

这是创建好的

然后点击右上方第一个

    添加虚拟机监控界面

    Console -> Graph Trees -> (Edit) -> Graph Tree Items

   2.Spine 多线程监控

        在虚拟主机server6上编译cacti-spine：
      <1>tar zxf cacti-spine-0.8.8h.tar.gz
      <2>cd cacti-spine-0.8.8h
         《1》yum install net-snmp-devel mysql-devel openssl-devel -y   ##解决依赖关系
         《2》yum install dos2unix autoconf automake binutils libtool gcc cpp glibc-headers glibc-devel -y
         《3》sh bootstrap
         《4》./configure
         《5》make && make install
      <3>cd /usr/local/spine/etc
         《1》cp spine.conf.dist /etc/spine.conf
         《2》vim /etc/spine.conf   ##做如下修改
      33 DB_Host        localhost
       34 DB_Database    cacti
       35 DB_User        cacti
       36 DB_Pass     redhat

       37 DB_Port        3306
      <4>su - cacti
