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
#

com2sec notConfigUser

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

view

view
systemview included .1.3.6.1.2.1.2
view
systemview included .1.3.6.1.2.1.25.1.1
view

# Finally, grant the group read-only access to the systemview view.
#

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 -c public
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！
