使用Cacti监控远程主机时的snmp.conf配置实例
使用Cacti监控远程主机时的snmp.conf配置实例使用cacti监控系统时，本机监控一般都比较好弄，可是在监控远程主机时，在snmp的配置这个地方经常容易出画，导致画不出图像来！下面这个是要被cacti监控的主机的snmp.conf的文件配置，需要修改的地方，你的snmp.conf文件中查找以下部分，把你的文件中没有的，添加上，就可以了。下面的IP地址是我随便写的10.10.10.10，这个要改成你的被监控的主机的IP地址。其它的地方照下面的复制粘贴就行了！
有几个地方貌似有点重复，没有太多时间去每个都检验，反正肯定是好用了，呵呵：）暂时就这样喽~~~这东西总是要真正的系统的去使用的时候，才能真正理解其中的每一步的意义。光看理论也没啥意思：）
# vi /etc/snmp/snmpd.conf //被监控的远程主机的
# sec.namesource community
com2sec notConfigUser 127.0.0.1 public
com2sec notConfigUser10.10.10.10 public
# Second, map the security name into a group name:
# groupName securityModel securityName
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
# Third, create a view for us to let the group have rights to:
# Make at leastsnmpwalk -v 1localhost -c public system fast again.
# name incl/excl subtree mask(optional)
view systemview included.1.3.6.1.2.1.1
view systemview included.1.3.6.1.2.1.2
view systemview included.1.3.6.1.2.1.25.1.1
view all included.1
# Finally, grant the group read-only access to the systemview view.
# group context sec.model sec.level prefixread writenotif
#accessnotConfigGroup"" any noauth exactmib2 none none
accessnotConfigGroup"" any noauth exactall none none
## sec.namesource community
#com2sec local localhost COMMUNITY
#com2sec mynetwork NETWORK/24 COMMUNITY
com2sec notConfigUserdefaultpublic
com2sec *.*.*.0 10.10.10.10/24 public
## group.name sec.modelsec.name
group MyRWGroupany local
group MyROGroupany mynetwork
group notConfigUserany zcom
#group MyRWGroupany otherv3user
## incl/excl subtree mask
view all included.1 80
view mib2 included.iso.org.dod.internet.mgmt.mib-2 fc
## context sec.modelsec.level prefix read writenotif
access MyROGroup "" any noauth 0 all none none
access MyRWGroup "" any noauth 0 all all all
配置完成后，重启snmp服务：
# service snmpd restart
然后在Cacti的主机使用snmpwalk命令测试一下：
# snmpwalk -v 1 10.10.10.10 -cpublic
显示一大堆下面的信息就是正常了！

OK,现在去Cacti的控制台里面去添加远程主机，并添加图像设置，就可以看到曲线图了应该！
