linux查询java进程 jstack 等信息

Posted 2021-09-16 老周21

事情背景：weblogic那总是有报什么线程独占之类的，所以搞个定时的探测出来，定时 jstack 一下，抓抓独占产生时候的信息

话不多说，直接上脚本了，拷上去测试就好了

 

#!/bin/bash

etime=$(date "+%Y%m%d%H%M%S")
JSTACK="/u01/soft/jdk1.6.0_45/bin/jstack"
JSTAT="/u01/soft/jdk1.6.0_45/bin/jstat"

#pid=`ps -ef|grep weblogic|grep -v grep|awk  \'{print $2}\'`
pid_9801=`ps -ef | grep weblogic | grep wsbsfwt | grep 9801 |grep jdk |awk \'{print $2}\'`
pid_9801_count=`ps -ef | grep weblogic | grep wsbsfwt | grep 9801 |grep jdk |awk \'{print $2}\' |wc -l`

pid_9804=`ps -ef | grep weblogic | grep wsbsfwt | grep 9804 |grep jdk |awk \'{print $2}\'`
pid_9804_count=`ps -ef | grep weblogic | grep wsbsfwt | grep 9804 |grep jdk |awk \'{print $2}\' |wc -l`

pid_9805=`ps -ef | grep weblogic | grep wsbsfwt | grep 9805 |grep jdk |awk \'{print $2}\'`
pid_9805_count=`ps -ef | grep weblogic | grep wsbsfwt | grep 9805 |grep jdk |awk \'{print $2}\' |wc -l`

pid_9806=`ps -ef | grep weblogic | grep wsbsfwt | grep 9806 |grep jdk |awk \'{print $2}\'`
pid_9806_count=`ps -ef | grep weblogic | grep wsbsfwt | grep 9806 |grep jdk |awk \'{print $2}\' |wc -l`

echo $pid_9801
echo $pid_9804

if [ $pid_9801_count -eq 1 ];then
  $JSTACK  $pid_9801 > /tmp/tmp_duzhan/logs/9801_jstack_${etime}.log
  $JSTAT -gcutil  $pid_9801 > /tmp/tmp_duzhan/logs/9801_jstat_${etime}.log
else
  echo "bucunzai"

fi

if [ $pid_9804_count -eq 1 ];then
  $JSTACK  $pid_9804 > /tmp/tmp_duzhan/logs/9804_jstack_${etime}.log
  $JSTAT -gcutil  $pid_9804 > /tmp/tmp_duzhan/logs/9804_jstat_${etime}.log
else
  echo "bucunzai"

fi

if [ $pid_9805_count -eq 1 ];then
  $JSTACK  $pid_9805 > /tmp/tmp_duzhan/logs/9805_jstack_${etime}.log
  $JSTAT -gcutil  $pid_9805 > /tmp/tmp_duzhan/logs/9805_jstat_${etime}.log
else
  echo "bucunzai"

fi

if [ $pid_9806_count -eq 1 ];then
  $JSTACK  $pid_9806 > /tmp/tmp_duzhan/logs/9806_jstack_${etime}.log
  $JSTAT -gcutil  $pid_9806 > /tmp/tmp_duzhan/logs/9806_jstat_${etime}.log
else
  echo "bucunzai"

fi

find  /tmp/tmp_duzhan/logs/ -name "*.log" -mtime +2|xargs rm -f

 

还有一个是清理2天内的信息
