SHELL脚本监控oracle alert日志

监控alert 日志

思路：按alert日志行号取当前最后一行和上一次扫描的行对比 大于等于上一次扫描的行 就从上一次扫描的行开始 扫描到最后一行

#!/bin/bashscriptHome=`dirname $0`scriptName=`basename $0`logDir=$scriptHome/logs#logfile=$logDir/$scriptName_$(date "+%Y%m%d").loglogfile=$logDir/ora-error.logrunfile=$logDir/run.logalertLogFile=/u01/app/oracle/diag/rdbms/orcl/orcl/trace/alert_orcl.logip=`ifconfig | sed '2q' | awk -F '[ :]+' '/inet/{print $4}'`oraErrMsg=ORA-mailTo=737735250@qq.comif [ ! -d $logDir ]; then   mkdir -p $logDirfiif [ ! -f $alertLogFile ]; then   echo "Error: $alertLogFile no such file or directory."   exit 1fitouch $runfilestartLine=$(cat $runfile)endLine=$(cat $alertLogFile | wc -l)if [ "x$startLine" == "x" ]; then  startLine=1else  startLine=$(expr $startLine + 1)fiecho "=== 正在获取警告日志信息..."if [ $endLine -le $startLine ]; then  #echo "未扫描到错误信息."  echo ""  exit 0fiecho "===$(date "+%Y-%m-%d %H:%M:%S") 扫描行${startLine},${endLine}..." >>  $logfile content=`cat $alertLogFile | sed -n "${startLine},${endLine}p"`oraError=`echo "$content" | grep "$oraErrMsg" | tee -a $logfile`if [ "x$oraError" != "x" ]; then echo "$oraError" | mutt -s "$(date "+%Y-%m-%d %H:%M:%S") $ip 警告日志告警" -b $mailTofiecho $endLine > $runfile

脚本会自动扫描指定的关键字，在这里指定的是ORA- ,然后只需要部署到crontab里即可。
