實(shí)驗(yàn)內(nèi)容：
1.監(jiān)控物理主機(jī)
2.Spine 多線程監(jiān)控
3.monitor監(jiān)控插件
1.監(jiān)控物理主機(jī)
在物理主機(jī)上配置如下：
<1>yum install net-snmp.x86_64 -y ##安裝snmp服務(wù)
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
72 # --

<4>snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex ##-v指版本,-c指密鑰,即客戶端snmp.conf里面所設(shè)置的,公認(rèn)的密鑰組為public(這也是snmp眾所都知的bug之一,不安全！,當(dāng)然也可以自己改個(gè)密碼),IP——MIB指獲取系統(tǒng)(物理機(jī))的IP信息
