1. IntroductionJstat is used to monitor the hotspot-based JVM for real-time command-line statistics on the use of its heap, and with jstat we can monitor the specified JVM as follows:-Loading and unloading of classes-View capacity and usage of new generation, Laosheng generation and durable generation-View the new generation, Laosheng generation and durable generation of garbage collection, including the number of garbage collected and the time taken by garbage collection-View the capacity and d

Many corporate LANs now have their own file servers for storing or sharing files for use by local area network users. However, in the process of setting up shared file access, it is common for shared files to be randomly copied, modified, or even deleted, which makes the security management of shared files face a greater risk. How can you make it possible for users to access shared files and prevent improper operation of shared files? I think that can be achieved through the following two ways:

In Unix-like systems, you can use top to view system resources, processes, memory usage, and other information. To view the network status, you can use tools such as netstat and nmap. To view real-time network traffic and monitor TCP/IP connections, you can use iftop. I. What is iftop? Iftop is similar to top... in Unix-like systems, you can use top to view system resources, processes, memory usage, and other information. To view the network status, you can use tools such as netstat and nmap. To

Mysql monitoring tool: zabbix + MPM (PerformanceMonitorforMySQL) MPM is mainly used to monitor various mysql parameter performance indicators. The following describes the configuration of MPM and zabbix: The following figure shows the configuration file diagram. It consists of two parts: 1. zabbix template: Template_FromDual.MySQL. *. xml 2. MPM agent perl module: FromDualMySQL *. pm Installation Method: 1

Real-time monitoring commands, watch is a very useful command, can help you to monitor the results of a command in real time, save the manual run over and over again. The two most common options for this command are-D and-N, where-n indicates how many seconds interval is executed "command", and-D indicates where the highlight has changed.Examples of usage:1) Execute the WHO command once every second to monitor the status of the server's current user l

The Linux system administrator should know the monitoring tool. If you want to monitor the performance of the Linux server, try the built-in shell commands and some additional tools. Many Linux distributions have "tons" of monitoring tools. These tools provide measurable information for observing system activities and identifying suspicious points that result in

Linux real-time monitoring tool vmstat The official definition of vmstat is vmstat-Report virtual memory statistics, which is the statistics of virtual memory. First, tracing: What is virtual memory? A: The virtual memory is a virtual file on the disk that can be used as the memory. Why is there virtual memory? A: The program needs to run through the memory. If the program consumes too much memory during ex

Android memory monitoring tool ddms --> heap. Original address To monitor the memory usage of an application process using heap, follow these steps:1. After eclipse is started, switch to the ddms perspective and confirm that the devices view and heap view are all open;2. Connect your phone to your computer via USB. Make sure that the phone is in "USB debugging" mode instead of "Mass Storage ";3. After the c

about 10.5, and every 3 seconds disk reads about 62KB, writes about: 110KB, this value is not an accurate value, why? Know why? Because of the time period problemThe best test is to find the average number of times or use the method to find the current valueAs shown below:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/6B/86/wKiom1Uvfk2jn_KzAAC-70HOJzU414.jpg "title=" 6.png " alt= "Wkiom1uvfk2jn_kzaac-70hojzu414.jpg"/>There are many more detailed extensions for Iostat, with the-X opt

No matter how careful you are, it is impossible to completely avoid bad code. At this time, some tools are required to help us check whether there is any place in the code that will cause memory leakage. The ddms in Android tools comes with a very good memory monitoring tool heap (here I use the ADT plug-in of eclipse, and take the real machine as an example, the situation in the simulator is similar ). To
