分享一个之前我用来巡检主机和Oracle的脚本，不过输出结果不是很美观，内容还是可以的...
主机巡检脚本：OSWatcher.sh
ps:这里的第10项，普通用户检查/var/log/messages很可能没有读权限，如有需要巡检此系统日志，建议切换root用户执行此脚本。

1. 创建目录并授权
# mkdir -p /home/oracle/scripts # chown -R oracle.oinstall /home/oracle/scripts/ # chmod -R 755 /home/oracle/scripts/
2. 两脚本都用oracle用户执行
切换到oracle用户，执行两个脚本：
$./OSWatcher.sh $./ORAWatcher.sh
3. 查看巡检内容
注意：ORAWatcher.sh脚本中数据库的默认连接串是：system/system，如果system密码不是这个，可以这样执行：./ORAWatcher.sh system/password
