需求：领导要求分析服务日志，计算出各个设备的在线时长，在线率，设备使用率等。


服务日志格式为：

2018-03-01 00:13:52,815 [protocol.handler.1][INFO] - cn.testin.trans.controller.req.script.HeartBeat.deviceLog---{"sdcardWriteable":0,"deviceAction":1,"sdcardAvail":10113417216,"wifiSsid":"testin03_default","rootEnable":0,"deviceid":"863563023966636","networkState":1,"errorMsg":"","minicapEnable":1,"deviceState":1,"romAvail":1655619584,"rpiid":"localhost","networkType":1,"ramAvail":1488954688,"debugMode":1,"errorCount":0,"batteryLevel":100}

以上标红部分：

deviceid: 为设备id， networkState:为网络状态，该值有1、0两个值  deviceState:为设备状态，该值有0、1、2三个值

此时执行完成，需要不到两分钟。

此前shell脚本：

#!/bin/bash
#show all deviceid counts
Today=`date "+%Y%m%d"`
#FileName='test.txt'
FileName='devicereport'
TempFile='count1.txt'
mysql_sql='mysql -uanaly -p****** '
cat ${FileName} | awk -F'---' '{print $2}' | jq '.deviceid'|sort|uniq -c >> ${TempFile}
for deviceid in `cat ${TempFile}|awk '{print $2}'`
do
   #find networkstate
   netstate_0=`grep $deviceid ${FileName}| awk -F'---' '{print $2}' | jq '.networkState'|grep 0 |wc -l`
   netstate_1=`grep $deviceid ${FileName}| awk -F'---' '{print $2}' | jq '.networkState'|grep 1 |wc -l`
   devicestate_0=`grep $deviceid ${FileName}| awk -F'---' '{print $2}' | jq '.deviceState'|grep 0 |wc -l`
   devicestate_1=`grep $deviceid ${FileName}| awk -F'---' '{print $2}' | jq '.deviceState'|grep 1 |wc -l`
   devicestate_2=`grep $deviceid ${FileName}| awk -F'---' '{print $2}' | jq '.deviceState'|grep 2 |wc -l`
   sumdevice=`grep $deviceid $TempFile|awk '{print $1}'`
#compute rate
   netstate_0_rate=`echo "scale=2;a=(${netstate_0}/${sumdevice})*100;if(length(a)==scale(a)) print 0;print a"|bc`
   netstate_1_rate=`echo "scale=2;a=(${netstate_1}/${sumdevice})*100;if(length(a)==scale(a)) print 0;print a"|bc`
   devicestate_0_rate=`echo "scale=2;a=(${devicestate_0}/${sumdevice})*100;if(length(a)==scale(a)) print 0;print a"|bc`
   devicestate_1_rate=`echo "scale=2;a=(${devicestate_1}/${sumdevice})*100;if(length(a)==scale(a)) print 0;print a"|bc`
   devicestate_2_rate=`echo "scale=2;a=(${devicestate_2}/${sumdevice})*100;if(length(a)==scale(a)) print 0;print a"|bc`
   Online_time=$(((${devicestate_0} + ${devicestate_1})/360))
   ${mysql_sql} -e 'insert into analy.device_data_report (date,deviceid,netstate_0_rate,netstate_1_rate,devicestate_0_rate,devicestate_1_rate,devicestate_2_rate,Online_time) values ('$Today','$deviceid','$netstate_0_rate','$netstate_1_rate','$devicestate_0_rate','$devicestate_1_rate','$devicestate_2_rate','$Online_time')'

此时执行完需要两个多小时。
