rrdtool 绘图

一些基础知识就不说了，直接上脚本吧

负载脚本：

 1 #!/bin/sh
  2 RRD_DIR="/var/www/html/graph"
  3 RRD_FILE="load.rrd"
  4 RRD_LOG="load.log"
  5 NOW_STRING=`date +%s`
  6 NOW=`date "+%Y/%m/%d %H:%M:%S"`
  7 LOAD_5=`uptime | awk '{print $10}' | cut -c 0-4`
  8 LOAD_10=`uptime | awk '{print $11}' | cut -c 0-4`
  9 LOAD_15=`uptime | awk '{print $12}' | cut -c 0-4`
