Windows Server 2008 has Windows Reliability and Performance Monitor, enabling it technology to freely gain the tools to easily monitor and analyze system performance and reliability. (Note: In some pre-release versions of Windows Server 2008, this feature is referred to as the Windows Performance Diagnostics console). Windows Reliability and Performance Monitor i

Springboot uses Spring Boot Actuator to Monitor the application, springbootactuator 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? In t

Monitor object 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

Windows 7 Resource Monitor is a powerful tool used to learn how processes and services use system resources. In addition to monitoring resource usage in real time, resource monitor can also help analyze unresponsive processes, identify which applications are using files, and control processes and services. The procedure is as follows: 1. Enter resource monitor i

Use Shell scripts to monitor KVM virtual machines Recently, a friend asked me what software I usually use to manage KVM virtual machines. In fact, I usually use the virsh command to manage virtual machines through the command line. Although redhat has a virtual machine management and monitoring platform, it can only be used on the redhat release. Other platforms are not associated with this software, including centos. If you use the virsh command to m

. Messages are sent to the primary service through a queue. If the data center is the same, it is better to write the Nagios plug-in. In this way, unified management is required. You only need to write the plug-in. If the data center is distributed, you can consider writing some scripts for message transmission between Nagios. writing your own code is not time-consuming and difficult to manage. However, collectD comes with a variety of plug-ins, such as system CPU disk utilization, MySQL, nginx,

Thread: A thread is an independent execution unit of a process. Each process has a main thread, except that the main thread can contain other threads. The significance of multithreading: multithreading helps improve the overall responsiveness of the program and improve the CPU efficiency. Multi-threaded application domains are quite unstable because multiple threads can run shared functional modules at the same time. To protect the application's resources from being destroyed, three locking mech

Linux system monitoring tools, such as Inotify-sync (file system security monitoring software), Glances (Resource monitoring tool), are currently in use in the Python language, Linux The system administrator can write a simple and practical script to monitor the Linux server according to the specific situation of the server he uses. This article describes the use of Python scripting to implement a monitoring script for the Linux server CPU memory netw

I want to view the SQL statement operated by this ajax request through the debug toolbar. what should I do if I encounter an error? can the debug debugging toolbar of yii2 only monitor ajax request

Although the Linux operating system is much more stable than the Windows operating system. However, this stability is relative. That is to say, the Linux operating system may also get angry. In some cases, the system's resource usage (including CPU or memory) may reach more than 90%. To this end, the system administrator still needs to monitor the usage of system resources when necessary. Today, I will introduce how to
