把脚本上传至cacti的screpts目录下：/var/www/html/scripts
注意修改脚本权限
测试：[[email protected] scripts]# ./get_snmp_network_data.sh -com sinolife -i 172.28.0.41 -o .1.3.6.1.4.1.15227.1.5.1.1.2.0
data:57
脚本可以根据nagios的nrpe脚本进行修改，但cacti的输出结构更简单。
变量:值 变量:值
即可！！
创建数据输入方法：
/bin/bash <path_cacti>/scripts/get_snmp_network_data.sh -com <community> -i <hostname> -o <OID>
输入字段有3个，两个可以"从主机派生"，从主机派生，需要选择一下。
不能从主机派生，则需要自己输入：
输出字段一个:
创建数据模板：查询cpu的OID，红色部分注意修改。
其他的memery, session 一样方法，只是oid不同
创建图形模板：
对象：图形类型等
创建主机，然后添加图形即可。
查看数据源：
图形文件：
/var/www/html/rra/61/664.rrd
检查是否有值传进来：
[[email protected] log]# rrdtool lastupdate /var/www/html/rra/61/664.rrd
getsessiondata
1452834361: 1221
You have mail in /var/spool/mail/root

值1221 已传入rrd图形。
