cacti监控IO状态
下载cacti-iostat.*这个文件解压cp scripts/iostat.pl/usr/local/bin/iostat.pl
echo "pass .1.3.6.1.3.1 /usr/bin/perl /usr/local/bin/iostat.pl" >> /etc/snmp/snmpd.conf重启snmpd服务cd /etc/init.d./snmpd restart
cacti所在的服务器cp snmp_queries/linux/iostat.xml/cactipath/resource/snmp_queries/cacti导入模板，这个就不写了!添加定时任务*/5 * * * * root cd /tmp && iostat -xkd 2 2 | sed 's/,/\./g' > io.tmp && mv io.tmp iostat.cache
如果是其他主机只需要iostat.pl /bin
