keep up with the overall operating rhythm, or because there is an old network switch in the system that may not continue to work due to a restart.In this case, the application-focused monitoring method shows its limitations. This requires more software-level and hardware-level metrics to evaluate each component in the system.At the hardware level, the first thing you can think of is a Web server and a database server, but they are just a tip of the i

18 command line tools for Linux performance monitoringDaily monitoring and debugging of Linux system performance is a heavy task for the system and network administrators. Five years after working as a Linux system administrator in the IT field, I gradually realized how difficult IT is to monitor and keep the system up and running. For this reason, we have compil

CPU of Linux system and performance monitoringPerformance optimization is the process of finding bottlenecks in system processing and removing them. This article was translated by sanotes.net webmaster Tonnyom in August 2009 from the Linux System and performance monitoring series. This article is the first in a series that describes CPU

problems because the subsystem cannot keep up with the overall operating rhythm, or because there is an old network switch in the system that may not continue to work due to a restart.

I. Operating System OptimizationFor operating system optimization, it is to increase the available memory capacity as much as possible, increase the CPU frequency, and ensure the read/write rate of the file system. Stress tests show that the CPU processing capability is stronger and the system runs faster when many concurrent connections exist ..[Applicable scenario] any project.Ii. Java Virtual Machine OptimizationSun's JVM should be selected. when meeting the project's needs, we should try to

What skills Modern network performance monitoring tools should have. Previously, enterprise network engineers had to provide network access and sufficient bandwidth for a variety of connected servers, applications, and end devices. From the OSI model perspective, these tools focus primarily on 1-4 layer networks. Because all traffic and data flows across a network share all of the bandwidth and queue resour

servers, Analysis servers, and Hadoop clusters, while the parameters to be monitored are related to the application or tool.There are many great tools for application monitoring, such as Datadog and new Relic.Metrics for application monitoring include: Memory of the JVM process The number of internal threads Disk IO Read/write operations on indexes microservices

All the content in this article is based on JDK 5, which may be different if JDK 6 is used.In the past few days, we have done some performance monitoring work, some of which are worth recording:JDK itself provides many tools based on command lines and guis. It is very useful to learn to apply them rationally.Jmap is a command line program that is used to view the number of objects in the JVM. directly input

1.0 performance monitoring Performance Tuning is a process of finding system bottlenecks and adjusting the operating system to eliminate these bottlenecks. Many System Administrators think that performance tuning is like cooking with recipes: simply setting a few system parameters can solve a problem. In fact, this is

This article reads the reading notes for the deep understanding of Java Virtual Machine-JVM advanced features and best practices, and it organizes the performance monitoring and Troubleshooting section of the virtual machine.About the two parts of the guide map or hope that you can personally test the experience, there are a lot of articles on the Internet, here are excerpts from several individuals think g

Java™platform, Standard Edition 6 (Java SE) focuses on improving performance, providing enhanced tools to manage and monitor applications and diagnose common problems. This article introduces the basics of monitoring and management in the Java SE platform and provides detailed information about the enhancements in Java SE 6.Java SE 6 provides an in-depth look at perform
