tool is tightly integrated into jrockit JVM, with very low overhead and easy access to virtual machine heap. Advantages of professional tools Once you know that a memory leak occurs, you need more professional tools to find out why the leak occurs. The JVM won't tell you. These professional tools obtain information about the memory system from the JVM in two way

: jconsole, jvisualvm, and Visual GC. Next we will learn about each GC monitoring method: Jstat JstatIs a built-in monitoring tool for Hotspot JVM. Hotspot JVM also has other built-in monitoring tools suchJpsAndJstatd. These three tools are sometimes required to monitor the

Jconsole can monitor the memory usage of Java processes on the remote host. This article explains how to use Jconsole to monitor WebLogic and Tomcat on a remote host.First, the environment1. Native Environment: Windows xp+jconsole (jdk1.6)2. Remote Environment 1:sunos (Solaris, jdk1.6) +weblogic3, Remote Environment 2:redhat (jdk1.6) +tomcatThis article will describe the configuration of the two environments, the configuration is basically the same, t

Full-featured built-in analyzer such as jconsole and visualvm sometimes cost more than they cost performance-especially in systems running on production software. Therefore, in the 2nd articles focusing on Java performance monitoring, I will introduce five command line analysis tools, allowing developers to focus only on one aspect of the running

usage, and they all provide statistics that include packets per second, packet, packet error, conflict, and so on. In Ethernet, a small amount of packet collisions is a normal phenomenon. If the wrong package is more than that, it might be a problem with the NIC. At the same time, although Netstat can count the network interface to send and receive data, it is difficult to determine whether the NIC is fully utilized. For example, if Netstat-i shows that there are now 2,500 packets sent from the
