几种监控用定时任务

网络连接数监控：

echo "`date +\"%H:%M:%S\"`" >> /home/count/netstatmonitor/netmonitor.`date +%Y%m%d`
netstat -n |grep 7001| awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'    >> /home/count/netstatmonitor/netmonitor.`date +%Y%m%d`

监控进程是否存在并重启：

#!/bin/bash
echo > /home/count/start/testOK.jsp
wget -q http://localhost:7001/templet/testOK.jsp -O /home/count/start/testOK.jsp &
#wget -q  --no-check-certificate https://localhost:8443/templet/testOK.jsp  -O /home/count/start/testOK.jsp  &
sleep 5
cd /home/count/start
size=$(ls -l | grep testOK.jsp | awk '{printf $5}')
zero=0
rightline=7
right=7

if [ $size -eq $right ]; then
    echo "`date +\"%H:%M:%S\"` sss is ok" >> /home/count/start/`date +%Y%m%d`.data
    rm -f /home/count/start/line
else
    echo "`date +\"%H:%M:%S\"` sss is not ok" >> /home/count/start/`date +%Y%m%d`.data
    process=$(ps -ef | grep tomcat | grep -c sss)
    if [ $process -gt $zero ]; then
        echo 1 >> /home/count/start/line
        linenum=$(wc -l /home/count/start/line | cut -c 1)
        if [ $linenum -gt $rightline ]; then
            rm -f /home/mecp/count/start/line
            num=$(ps -ef | grep tomcat | grep sss | head -n 1 | awk '{printf $2}')
            kill -9 $num
            sleep 10
            num=$(ps -ef | grep tomcat | grep -c sss)
            if [ $num -gt $zero ]; then
                num=$(ps -ef | grep tomcat | grep sss | head -n 1 | awk '{printf $2}')
                kill -9 $num
                sleep 10
            fi
            . /home/sss/setenv.sh
            /home/tomcat-6.0.32/bin/startup.sh
        fi
    else
        rm -f /home/count/start/line
        . /home/setenv.sh
        /home/tomcat-6.0.32/bin/startup.sh
    fi
fi

做时间同步：
[root@sss ~]# crontab -l

*/30 * * * *  /usr/sbin/ntpdate 40.40.40.100

执行sql操作

#!/bin/bash
v_date=$(date +%Y%m%d);
/oracle/product/10.2.0/bin/sqlplus -s 'name/passwaord@sid'<<EOF
set pages 0
set feed off
set heading off;
set feedback off;
set verify off;
set trimout on;
set trimspool on;
set trims on;
set linesize 4000;
set pagesize 4000;
spool /home/resourcesub_points_rec_$v_date.csv
SELECT '1'||','||trim(DONEDATE)||',' FROM ponitsinfo where substr(donedate,0,8) =(select to_char( dt ,'YYYYMMDD') dt from (select sysdate-1 dt from dual));
spool off
EOF
