Three tools for performance monitoring in LinuxGuideHow to manage Linux Hosts? The 18 weapons can be regarded as Swiss Army knives. One or two weapons can be claimed. The most common one is the three brothers of the stat family. What are the main computer resources? CPU, memory, and disk? Although there are many cloud computing technologies, it is still necessary to start investigating whether a system is r

During O M, people often experience server performance problems, such as I/O, CPU, memory, and network bottlenecks. So how can system O M be done? The following tools are helpful for refreshing your mind ~ (@ ^ _ ^ @)~ (1) Top Here, Rocky wants to clarify one point, and believes that the best practice of top is: "Find the process that consumes the most CPU resources" After finding it, press [p] and force it to be sorted by CPU usage Different fro
