1. Process ManagementA process is a program or command being executed, each of which is a running entity that has its own address space and consumes a certain amount of system resources.The role of process management is to determine the health status of the server, view all processes in the system, and kill the process. It is generally possible to terminate a process with the correct command, only to force the kill process if the termination fails.(1) View all processes in the system① ps aux com

a process performed in the foreground, but not all processes are performed in the foreground, and many processes are hidden in the background. Use the command ps-e to display all processes. Process Performance Detection commands Top command: Linux uses the top command to show the CPU usage as the first few processes. The command can sort tasks by CPU usage, memory usage, execution time, and many of the features of the command can be set through interactive commands or in personal customizat

is always 0, that is, in the form of "major: 0". It can also be abbreviated as "major: for example, queue 1:0 can be abbreviated as 1 :. It must be noted that major must be unique among all queues of a nic. For a category, its major must be the same as its parent category or the major of its parent queue, minor must be unique within a queue (because the category must be included in a queue ). For example, if queue 2 contains two classes, the handles of these two classes must be in the form of 2

To view or monitor disk read and write performance in Linux, you can use the Iostat command, which is described in this section for its specific use. 1.

(not reaching the app's memory limit) First you need to get the maximum memory value available to the VM (MB). Exceeding this value triggers the outofmemory exception, and it is important to note that the image stored in LRUCache is calculated in kilobytes and remembers the unit conversion when calculating the storage size.Final intMaxMemory = (int) (Runtime.getruntime ().
