rrdtool 监控 网络流量

在被监控的机器上面

yum  -y install net-snmp*
 vi /etc/snmp/snmpd.conf

com2sec notConfigUser  10.10.10.210(这里写监控机的IP)   cctvcj
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser
view all    included  .1                               80
access  notConfigGroup ""      any       noauth    exact  all none none
