Linux端口监控脚本
最近jboss进程经常无缘无故的被Halt，怀疑是某同学远程Debug时，直接点击了Eclipse上的Terminate按钮。但是又没有证据，所以写了一段脚本，专门监控8787端口的占用情况，脚本如下：#! /bin/sh#Author lanbo.xjLSNPORTS="8787";INTERVAL=60;iter=0;LOGPATH=$HOME/wlbmywlb/logs;if [ -n $LOGPATH ]; then mkdir -p $LOGPATH; fi;while [ 1 ]; do for port in $LSNPORTS doCCTLST=`netstat -an | grep ".$port" | awk 'BEGIN{OFS="|";}{print $1,$2,$3,$4,$5,$6,$7;}'`;LOGDATE=`date +%Y-%m-%d`;LOGFILE="${LOGPATH}/netstat[${port}]-${LOGDATE}.log";LOGTIME=`date '+DATE:%Y-%m-%d %H:%M:%S'`;for ns in $CCTLSTdo NETLST=`echo $ns | awk -F"|" 'BEGIN{OFS=" ";}{print $1,$2,$3,$4,$5,$6,$7;}'`; iter=`expr $iter + 1`; loginfo=`echo "$LOGTIME" ">>" "$NETLST"`; echo "$loginfo" >> $LOGFILE;#echo "$loginfo";done;echo "$LOGTIME >> Total connections[$port]: " $iter >> $LOGFILE;#echo "Total connections[$port]: " $iter;iter=0;sleep $INTERVAL; done;done;
