编写Bash Shell通过gnuplot绘制系统性能数据图的方法

使用步骤：
1.设置一个定时任何 执行getperf.sh，采集性能数据
2.将采集到性能数据文件，如：192.168.1.1.tar.gz 解压
3.将性能分析的脚步performance_analyse.sh 放到解压后的目录中
4.安装gnuplot程序（这里下载）

5.将字体文件夹，拷贝到/usr/share/fonts/目录
6.直接运行 bash performance_analyse.sh
getperf.sh脚本内容如下：

#################################################
#说明：
# 定义时间TIMES参数，表示采集的次数，
# 采集时间 = TIMES * INTERVAL
#eg:
# TIMES=180 , INTERVAL=10 采集时间就是半小时
