linux 串口监视工具
As a system administrator monitoring systems is very important job. Actually we can state that half of system administrating is monitoring and anticipating systems and their events. In this tutorial, we will look at Linux monitoring tools and their features. As I know there is a lot of tools to monitor and debug Linux system, network, disk, process, and applications so I have categorized them like below
作为系统管理员，监视系统非常重要。 实际上，我们可以说，系统管理的一半是监视和预测系统及其事件。 在本教程中，我们将研究Linux监视工具及其功能。 据我所知，有很多工具可以监视和调试Linux系统，网络，磁盘，进程和应用程序，因此我将它们归类如下
