此脚本为上次发布版本的更新版,添加了些内容,增加了用户体验!
使用方法:1.根据自己的实际环境新建自己的目录 2.将脚本’run.sh‘、'MonitorOS.py'、'alter_diskpath.sh'放到新建的目录下,并添加可执行权限 3.执行'alter_diskpath.sh'脚本来修改要监控的磁盘挂载目录!(注意:建议一次性的正确输入,此脚本未添加异常处理,执行后输错需要手动进入py脚本中手动修改!参考命令:“df -hT”) 4.执行'run.sh'脚本来启动监控程序,参考命令:./run.sh start | stop | status | restart 5.查看当前目录下面的monitoros.log日志来获取您的Linux系统性能信息 6.日志输出路径可自定义修改,在Crontab.sh脚本中修改即可 (默认路径为当前目录下,默认为每5分钟输出一次) 7.关于日志变大的清理方法,使用Linux自带的crontab中加入定时清空日志即可 此脚本作者还在持续优化中...... (更新时间2021.11.23)
alter_diskpath.sh代码如下:
- #!/bin/bash
- read -p '请输入本地环境要监控的磁盘路径:' input
-
- path=$input
-
- eval sed -i 's#DiskPath#${path}#g' MonitorOS.py
- echo $?
-
- echo '输入成功!'
Crontab.sh代码如下:
- #!/bin/bash
- #执行py脚本启动监控
- while true
- do
- python3 MonitorOS.py >> ./monitoros.log
- sleep 300
- done
run.sh代码如下:
- #!/usr/bin/bash
-
- APP_NAME=Crontab.sh
-
- #使用说明,用来提示输入参数
- usage() {
- echo "Usage: sh 执行脚本.sh [start|stop|restart|status]"
- exit 1
- }
-
- #检查程序是否在运行
- is_exist() {
- pid=$(ps -aux | grep ${APP_NAME} | grep -v grep | awk '{print $2}')
- #如果不存在返回1,存在返回0
- if [[ -z "${pid}" ]]; then
- return 1

- # nohup /home/paas/jdk1.8.0_202/bin/java -jar ${PARAMS} ${APP_NAME} > /dev/null 2>&1 &
-

- fi
- }
-
- #停止方法
- stop() {

- #重启
- restart() {

- start
- }
-
- #根据输入参数,选择执行对应方法,不输入则执行使用说明
- case "$1" in
