實戰Cacti網絡監控(2)——搭建Spine輕量級框架實現多線程監控

本次實驗接著上次實驗的環境。實戰Cacti網絡監控(1)——基礎安裝配置

實驗內容：

1.監控物理主機

2.Spine 多線程監控

3.monitor監控插件

    1.監控物理主機

        在物理主機上配置如下：
        <1>yum install net-snmp.x86_64  -y    ##安裝snmp服務
             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>網頁端配置
        打開網頁http:172.25.254.10
        在左邊選Device 然后點擊Add

這是創建好的

然后點擊右上方第一個

    添加虛擬機監控界面

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

    2.Spine 多線程監控

        在虛擬主機server6上編譯cacti-spine：
        <1>tar zxf cacti-spine-0.8.8h.tar.gz
        <2>cd cacti-spine-0.8.8h

            《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
