cacti有图无数据
如图，配置好了半天，客户端仍无数据；-nan就是不正常的了。下面就是解决办法：
在客户端操作：
vim /etc/snmp/snmpd.conf #更改如下
# sec.namesource community
com2sec notConfigUser192.168.20.168(cacti服务端的IP) public
# 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
view systemview included .1.3.6.1.2.1.25.1.1
view all include .1
# group context sec.model sec.level prefix read writenotif
accessnotConfigGroup "" any noauth exactall none none
效果如下图：
重启客户端
service snmpd restart
再查看正常了：
