Linux performance monitoring and analysis-CPU performance indicators 1. CPU usage ratio of user processes 2. CPU usage ratio of system processes 3. WIO, waiting for I/O is the ratio of the CPU in idle state. 4. CPU idle rate 5.

Analysis on single CPU usage of java application linux service 100%, javalinux In the previous project process, performance tests were performed on the linux server after the project was completed. When the Service ran, it was found that the cpu usage was very strange. The java application ran a single

Scaling_available_governors to know which governor the device supports, such as my device support OnDemand userspace interactive Performance, and so on, each governor has a different frequency selection criteria, such as OnDemand will be based on the workload of the system to select the frequency, if the current workload more than a certain threshold, the frequency table selection of the maximum frequency, Several other governor have the opportunity to introduce later. Assuming a governor choos

Description Because of all the original, we may need to look at the Linux Server board model, CPU model, memory size, the number of memory lines. Because the server uses a RAID card, the usual view of the hard drive information can not be used, to be added back later!

In Linux, use python to call the top command to obtain the CPU usage. This article is intended to use python to call the top command to obtain cpu usage, but there is no idea at the moment.To obtain the cpu utilization, you can use the top command to redirect it easily. The command is as follows:Copy codeThe Code is as

The concept of Load average originates from UNIX systems, and although the formulas vary from one family to the other, they are used to measure the number of processes that are using the CPU and are waiting for the CPU, in a word, the number of runable processes. So load average can be used as a reference for CPU bottlenecks, and if it is larger than the number o

On-line Java application, in the peak of the Business Times often appear CPU run high, need to see real-time thread CPU situation, the following is a very good script, you can quickly export the CPU of each thread, combined with Jstack log, to the specific thread class name. First, get the process ID of the JVM: Copy Code code as follows: Ps-ef|

You want to know the CPU usage during Java programming so that you can decide whether to load the task. First with Google search, Windows environment can use JNI through the API function Getprocesscputime () to get, and someone gave the source code. Linux seems to have no one to give the source code, so decided to write one, after practice, and finally succeeded, is to post code, and share with you.Thinking

Everyone knows that everything in linux is a file. There is a/proc directory under the root directory of linux/unix, this/proc is a mechanism used by the kernel and kernel module to send information to the process (so it is called "/proc "), this pseudo file system allows interaction with the internal data structure of the kernel to obtain useful information about the process. on the fly, you can change the
