Introduction to common linux performance monitoring tools and linux performance monitoring tools Record several frequently used ones.1. top/htop As we all know about top, there are several common parameters: (you can also start and interact) -D: Set the delay time-S: accumulative time mode k: End Process q: Exit topZ:

EventSource interface. This article describes how to use the asynchronous Beans EventSource to construct a thread factory, which includes a downloadable example called a concurrency adapter (Concurrent Adapter) that can be used with a third-party thread pool implementation to create the ability to A fast thread pool that works on a WebSphere application Server. Global thread pool WebSphere application S

ordered by executions:The top SQL that is sorted by the number of executions of SQL is recorded. This sort shows the number of SQL executions that are within the scope of the monitoring.4.6 SQL ordered by Parse Calls:Top SQL that records the number of soft parse times for SQL. When it comes to soft-parsing (soft prase) and hard-parsing prase, it's impossible to say how Oracle handles SQL.4.7 SQL ordered by sharable Memory:The top SQL that SQL occupie

All of the customer's web containers were replaced with WebSphere from the previous year, with a version of 5.1. Initially, you don't know how to optimize performance, just use ant to make a war package for project and publish it through the WS Management Console. But when the customer is actually using, sometimes the response is slow, and finally even WS is hang. With the Kill-java process number generated

It is also necessary to perform basic monitoring on a single server or VPS. In the past, Zhao Rong did not monitor VPS, because when some servers were added, his performance became even more tense. There are also a lot of foreign server performance monitoring websites, but it is a little difficult for people like Zhao

System optimization is a complex, complex, and long-term task. monitoring, collection, testing, and evaluation are required before optimization. After optimization, testing, collection, evaluation, and monitoring are also required, it is also a long-term and continuous process. It is not to say that the optimization is now done, the test is done, and it can be done once and for all in the future. It is not

is divided evenly into three parts, the eldest brother occupies two, and the younger generation occupies a copy. Reference Sun Java System application Server Enterprise Edition 8.2 Performance Tuning guide), this ratio is not suitable for all situations, especially when local variables in your application are far greater than the global variables, and a large number of local variables have a short life cycle. How to reasonably configure the proportio

Brief introduction Many Java applications today rely on a complex set of distributed dependencies and moving parts. Many external factors can have an impact on the performance and availability of your application. These effects are largely not completely eliminated or resolved, and are difficult to simulate accurately in a prebuilt environment. Stuff happens. However, you can create and maintain a comprehensive system to monitor the entire ecosystem

SNMP collects data on server performance, such as CPU usage, memory usage, CPU load, number of system processes, disk space usage, network traffic, disk I/O, and so on, while using the monitoring treasure to process these data can be visually displayed. The following describes how to configureInstalling SNMP1, tohttp://www.net-snmp.org/Download the latest version of the SNMP installation package.1. wgethttp

Non-intrusive monitoring of PHP application performance monitoring analysis The so-called non-intrusive monitoring of PHP application performance means to monitor the system without modifying the existing system code. Such a system can be easily applied to PHP applications.
