标签:cmd jmap EAP read 采集 stat let pre 数据采集
笔者在进行压测过程中,用shell 编写 怎么采集 heap 和 io 的性能数据,现分享如下:loop_count=1
count=1
#sleep 3
echo -n "Please input pid:"
read cmd1 cmd2 cmd3
echo "" > heap${cmd1}.log
echo "" > heap${cmd2}.log
echo "" > heap_${cmd3}.log
fun_io() {
echo "磁盘 I/O 采集数据开始! "
while (($loop_count <=10))
do
sleep 1
iostat -x 3 1 >> system.log
let "loop_count++"
done
echo "磁盘 I/0 采集数据结束!"
}
fun_mem() {
echo "HEAP 数据采集开始!"
while (($count <=3 ))
do
sleep 5
if [ ${cmd1} -gt 1 ]
then
jmap -heap ${cmd1} >> heap_${cmd1}.log
else
echo "没有输入pid1"
fi
sleep 1
if [ ${cmd2} -gt 1 ]
then
jmap -heap ${cmd2} >> heap_${cmd2}.log
else
echo "没有输入pid2"
fi
sleep 1
if [ ${cmd3} -gt 1 ]
then
jmap -heap ${cmd3} >> heap_${cmd3}.log
else
echo "没有输入pid3"
fi
let "count++"
done
echo "HEAP 数据采集结束!"
}
fun_io
fun_mem
