最近时不时有朋友问我关于服务器监控方面的问题,问常用的服务器监控除了用开源软件,比如:cacti,nagios监控外是否可以自己写shell脚本呢?根据自己的需求写出的shell脚本更能满足需求,更能细化主机监控的全面性。
下面是我常用的几个主机监控的脚本,大家可以根据自己的情况在进行修改,希望能给大家一点帮助。

放在crontab里每小时自动执行:
|
1
|
0 * * * * /home/check_xu.sh |
这样会在/home/oslog/host_yyyymmdd/hh目录下生成各小时cpu、内存、网络,IO的统计数据。
如果某个时间段产生问题了,就可以去看对应的日志信息,看看当时的主机性能如何。
