The first is to get a particular process object, either by using the Process.getprocesses () method to get all the processes running on the system, or by using the Process.getcurrentprocess () method to get the process object that the current program corresponds to. When you have a process object, you can create the PerformanceCounter type object by using the process object name to get CPU and memory usage

The following is a shell script code that limits the CPU usage of processes: renice + 10 'psaux | awk' {if ($3 gt; 0.8 amp; id-u $1 gt; 500) print $2} ''where ps is used to obtain process information, in fact, the % CPU column in ps indicates that the process actually occ

In fact, in a Linux server, it is acceptable for a user process to run for a long time. And the CPU is too high to make other users unbearable, and it is likely that the user program has a problem, this time the system should automatically prevent such processes continue to consume system resources. The si

It is also important to limit the use of the CPU to prevent server crashes. This is especially useful for any custom scripts you might run in a crontab.

View cpu usage information of processes in memory. For Linux Command-TOP, we use the top command to view CPU usage. Top does not produce output, and the screen content remains unchanged. It refreshes the screen to display new information. Therefore, if you only execute top and keep the screen open, the screen will alwa

-intensive processes:The top command looks at processes that are CPU intensive, enters "K" directly, and then enters the PID number of the corresponding process to terminate the process.2.2 With top view CPU is idle, but the load is relatively high situation:Load average is an evaluation of the CPU load, the higher the value, the longer the task queue, the more t

When the site traffic is large, mysql is under a high pressure. when the CPU usage of mysql exceeds 300%, it cannot provide services, and it is almost stuck. at this time, the best way is to restart the mysql service. This is unpredictable. we don't know when mysql's usage reaches 300%, or we need to write a program to make regular judgments. After learning shell
