rrdtool作图查看ping的响应时间

rrdtool作图查看ping的响应时间

 

为了测试到远程一台机器的ping的响应时间，要每隔5分钟ping一次，每次发送10个数据包。然后看min max avg这三个值，为了更直观的表示，现将每次执行后ping返回的数据输入到rrdtool的数据库中，最终生成图片。可以一目了然的看到变化曲线。
下面贴下我的shell吧。
本文假定你已经安装rrdtool,（/usr/local/rrdtool)
第一步：建立数据库
rrdtool=/usr/local/rrdtool/bin
RRD_DB_FILE=/home/ldc_user/ping-ms.rrd

NOW=`date +%s`
MONTH_IN_SEC=2629743
MONTH_AGO=$(($NOW-$MONTH_IN_SEC))

if [ -e "$RRD_DB_FILE" ]
then
echo “file exists: $RRD_DB_FILE”
else
$rrdtool/rrdtool create $RRD_DB_FILE –step 300 \
DS:min_ms:GAUGE:600:0:500 \
DS:avg_ms:GAUGE:600:0:500 \
DS:max_ms:GAUGE:600:0:500 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

echo “file created: $RRD_DB_FILE”
fi
第二步
为数据库更新数据
rrdtool=/usr/local/rrdtool/bin
RRD_DB_FILE=/home/ldc_user/ping-ms.rrd
VALUE=`tail -1 request |cut -c 5-|cut -d= -f2|cut -c 2-|awk -F/ ‘{print $1″:”$2″:”$3}’`
#VALUE1=`tail -1 request |cut -c 5-|cut -d= -f2|awk -F/ ‘{print $1}’`
$rrdtool/rrdtool update $RRD_DB_FILE N:$VALUE

第三步：
做图
#!/bin/bash
rrdtool=/usr/local/rrdtool/bin
RRD_DB_DIR=/home/ldc_user/
RRD_DB_FILE=/home/ldc_user/ping-ms.rrd
ONE_DAY_AGO=$(($NOW-86400))
ONE_WEEK_AGO=$(($NOW-604800))
ONE_MONTH_AGO=$(($NOW-2629743))
ONE_YEAR_AGO=$(($NOW-31556926))

# $1 -> period (secondes)
# $2 -> period (text)
do_rrdgraph() {
$rrdtool/rrdtool graph “request-ping_$2.png” -s $1 -h 120 -w 500 -a PNG -t “Ping of request (last $2)” \
-v ms \
–base=1000 \
–alt-autoscale-max \
–lower-limit=0 \
–rigid \
–units-exponent 0 \
–x-grid MINUTE:10:HOUR:1:HOUR:4:0:%X \

GPRINT:b:AVERAGE:”%.2lf” \
LINE1:c#FF0000:”max_ms. \: ” \
GPRINT:c:AVERAGE:”%.2lf”
}
# Launch
do_rrdgraph $ONE_DAY_AGO day
do_rrdgraph $ONE_WEEK_AGO week
do_rrdgraph $ONE_MONTH_AGO month
do_rrdgraph $ONE_YEAR_AGO year

rrdtool安装，需要依赖不少东西。一般的的源还没他。
