ForLinuxFor beginners of the operating system, install and useJprofiler6Analyzing the server application status is not a simple task. Don't worry. As long as you read the next article, installing jprofiler6 won't be a difficult task. 1. When an application encounters a problem, you can use jprofiler to analyze the cpu, memory, thread, and other States to help troubleshoot the problem; 2. Here I

and cannot be invoked frequently. When we tried it, we wrote a JMS connection pool, called the start () method each time the connection was taken out of the pool, and called the Stop () method when it was returned, but later found with Jprofiler, The average CPU time is consumed by both methods. 1.3 Start () to receive messages Connection the start () method call to receive a JMS message. If you do not call this method, you can send a message, but yo

fast Xx:+useconcmarksweepgc CMS GC, which features only jdk1.5, a later version, that uses GC estimation triggers and heap occupancy triggers. We know that frequent GC will cause the ups and downs of the JVM to affect the efficiency of the system, therefore, using the CMS GC can be in the case of increased GC, each GC response time is very short, such as the use of CMS GC after Jprofiler observation, the G

course, can also use a variety of artifact-assisted positioning, such as Jprofiler .3 What is a CPUCPU: Interprets computer instructions and processes data in computer software.The performance of the computer is largely determined by the performance of the CPU, and the performance of the CPU is mainly reflected in the speed of its running program. performance metrics that affect operating speed include par

1.1 do not establish and close the connection frequently JMS uses a long connection, a program, as long as the JMS server to maintain a connection on it, do not frequently establish and close the connection. Frequent establishment and shutdown of the connection, the performance of the program has a great impact. This is not the same as JDBC. 1.2 Connection of the Start () and Stop () method is expensive. The connection start () and Stop () methods of JMS are expensive and cannot be invoked frequ

We all know that. NET has its own memory (garbage) recovery mechanism, unless there is some data (methods) of long-term possession of memory does not follow the garbage collection function to free memory, so that we often say that the memory leaks, memory growth is not released and other issues caused by aps.net website or c/ The user of the S application is not working properly. The end result will be the user through the customer service personnel or technical support staff to complain about t

When we do Java development, we need to stress test the program before going online, to fully monitor the performance of the program, to understand the CPU, memory, gc,classes, thread, etc. of the JVM, or to run the program in order to diagnose problems or optimize the process. There are more tools on the market for Java profiling, such as commercial jprofiler,jclarity and so on, there are free JDK's own tools, such as VISUALVM,JCONSOLE,JMC and so on,

This article is for JPROFILER9 Windows clients to monitor Tomcat on a remote Linux server The following steps need to be noted for the normal installation of Win Jprofiler9 Key Step 1 Tick create archive with profilling agents in the directory Select a local folder, such as a desktop It will then generate a Jprofiler TRZ package for the remote Linux agent. Notice what's generated here. Unzip the contents of the folder and upload it to the Linu

The STS and Virgo environments have been configured above, and the Virgo server can be successfully run. Next we will use STS to build several projects. We simulate an example of registration. In our actual case, data is sometimes written to the database, written to a file, or written to the memory, which is convenient for different operations. This example may not completely explain the problem, but it is enough to explain how to build a project th
