把vmstat统计的信息以图表的形式呈现出来

分类： LINUX

2011-09-09 18:35:13

 

1、脚本名字:vmplot.sh

 

2、脚本的作用:

把vmstat统计的信息通过图像的方式形象的呈现出来。

 

3、脚本的用法:

# vmstat 1 100 > /tmp/vmstat.out

# vmplot.sh -i /tmp/vmstat.out -o results

 

4、脚本需要的环境:

 

1、yum install gnuplot -y  安装gnuplot命令

2、yum install sysstat  -y   安装vmstat命令

3、 需要安装浏览器

 

5、脚本内容:

 

#!/bin/sh

 

 

INFILE="vmstat.out"

OUTDIR="/tmp"

DATAFILE="vmstat.data"

LABEL=""

SAMPLE=""

 

X_UNITS="Minutes"

DEFAULT_SIZE="set size 0.75, 0.6"

 

[ -z `which gnuplot 2>/dev/null` ] && echo "gunplot must be installed for this to work" && exit 1

 

while getopts "i:o:x:l:s:" opt; do

        case $opt in

               i)

                       INFILE=$OPTARG

                       ;;

               l)

                       LABEL=$OPTARG

                       ;;

               o)

                       OUTDIR=$OPTARG

                       ;;

                x)

                       X_UNITS=$OPTARG

                       ;;

        esac

done

 

if [ ! -f "$INFILE" ]; then

        echo "$INFILE does not exist."

        exit 1

# This is based off vmstat with a header like:

# r  b   swpd   free   buff  cache   si   so    bi    bo   in    cs us sy id wa

 

# Make 0 the first point for each graph

# Also add another column at the end to represent total processor utilization.
