实战Cacti网络监控(2)——搭建Spine轻量级框架实现多线程监控

本次实验接着上次实验的环境。实战Cacti网络监控(1)——基础安装配置

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
