介绍在FreeBSD平台下如何安装和使用mrtg来监控cpu、内存、交换分区、TCP连接以及本机网卡流量
1.安装
#安装apache2
cd /usr/ports/www/apache2
make install clean
#安装p5-SNMP
cd  /usr/ports/net-mgmt/p5-SNMP
make install clean
#安装mrtg
cd /usr/ports/net-mgmt/mrtg
make install clean
2.编写配置文件
LoadMIBs: /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt
WorkDir: /usr/local/www/data/mrtg
Language: chinese
