For every system administrator or network administrator, it is very difficult to monitor and debug Linux system performance issues every day. I've had 5 years of experience working with Linux administrators and know how to monitor the system to keep it running properly. To do this, we have written 20 command-line system monitoring tools that are useful and most commonly used by Linux/unix system administrat
Often have friends will encounter a monitor without signal, compared to display without any display, monitor no signal computer failure is easier to solve. Why do you say that? In fact, the reason is very simple, if the monitor does not show any, we can not easily judge whether the problem is a monitor or computer host
Many readers are interested in System Safety Monitor (SSM. It is a Russian system monitoring software that monitors system-specific files (such as registries) and applications.

Install and start (you can manually run syssafe.exe) SSM in the installation directory, click Close this windows (Close Window) in the pop-up logo window t
Here we will introduce the C # Lock keyword. It can define a piece of code as a critical section. A mutex can only be executed by one thread at a time, while other threads must wait.
C # language is worth learning a lot. Here we mainly introduce the C # Lock keyword, including the locking of an object in the monitor class.
C # provides a lock keyword, which defines a piece of code as a critical section. A mutex section allows only one thread to

The Framework provides three locking mechanisms: the Monitor class, the Lock key word, and the Mutex class.
In general, lock and monitor can lock objects or functions, while mutex is generally used to lock functions and ensure that functions are synchronously called between different threads, without being affected by the thread priority. When the lock and monitor
One. Monitor usage Maintenance: 1. Display should be placed as far as possible away from the strong magnetic field, such as High-voltage wire, speakers, etc., otherwise the picture tube is easily magnetized. 2. Use the display to orient the monitor as far as possible, because the display factory adjustment is orient-oriented, so that the monitor is affected b

The characteristics of microservices determine that functional modules are deployed in a distributed manner. Most functional modules run on different machines and interact with each other through service calls, the frontend and backend business flows are processed and transmitted by many microservices. If an exception occurs, how can we quickly locate the problem?

1. monitor. the enter (object) method is to obtain the lock, monitor. the exit (object) method is to release the lock, which is the two most commonly used methods of monitor. Of course, to avoid the lock being released due to exceptions after the lock is obtained, therefore, you need to release the loc

In many computer accessories, the longest life of the components on the number of monitors. For example, my computer has been upgraded many times, but it is the 15-inch monitor that has stayed with me. Because the monitor is used for a long time, it is easy to be affected by environmental factors including temperature, humidity, dust, electromagnetic interference, electrostatic and so on, causing different
