CPU usage. T is sorted by time/accumulated time. W writes the current settings to the ~/.TOPRC file. This is the recommended way to write top configuration files. (7) Last skill: Top command Tips 1. Enter uppercase P, the result is sorted by CPU consumption in descending order. 2. Enter capital M, and the results are sorted in descending order of memory consumption. 3. Press the number 1 to show the load of all CPU cores. 4, top-d 5 refresh every 5 seconds, default 1 seconds 5. Top-p 4360,4358

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?
