Joe Zonker Brockmeier mentioned five tools to monitor and improve Linux system performance in an article on the Linux Foundation website.
These five tools cover Kernel optimization, network monitoring, and System monitoring. They are KDE System Monitor, Dstats, The Sysstat Auite, Ifstat network
.
Third, test whether JMX successfully configured
Start Tomcat, enter in Windows command window: Netstat-aon | Findstr "8999" If this port is already in use, it proves that the JMX configuration was successful
Four, turn on JMX monitoring
Run%java_home%\lib\jconsole.jar
Enter Tomcat machine IP, port input 8999
If you are running on this computer, you can enter
grouped by enclosing units, and the analysis of memory leaks mainly uses the functions of the "Heap histogram" and oql tags. The former can find the object with the largest total capacity in memory. The latter is a standard object query language that uses SQL-like syntax to query statistics on objects in memory.Vi. Jstack:java Stack Trace ToolThe Jstack command is used to generate a thread snapshot of the current moment of the virtual machine. The thread snapshot is the collection of method sta

If you are unfamiliar with the six open-source system monitoring tools, you are advised to refer to the relevant technical documents.1. Nagiox-network monitoring software
Nagios is well-known and undoubtedly the best system monitoring tool. As you know, most O M teams use this tool, and so far, no tool exceeded it. Ho
Linux performance analysis sar command explanation SAR (system activity Reporter System Activity Report) is currently one of the most comprehensive system performance analysis tools in Linux. It can report system activities from multiple parties, including: file read/write, system call usage, disk I/O, CPU efficiency, memory usage, process activity and IPC-related activities.
Common sar command formats

JVM Introduction to Monitoring ToolsVISUALVM is a visual tool that integrates multiple JDK command-line tools to provide you with powerful analytical capabilities. All of this is free! The command-line tools It includes are jps,jstat,jmap,jinfo,jstack,jconsole, which are consistent with the standard version of the JDK.JPS: Similar to PS on UNIX, used to show the
2015-12-27 iOS DevelopmentFor every system administrator or network administrator, it is very difficult to monitor and debug Linux system performance issues every day. I've had 5 years of experience working with Linux administrators and know how to monitor the system to keep it running properly.To do this, we have written 20 command-line system monitoring tools that are useful and most commonly used by Linu
The JDK itself provides many convenient JVM performance tuning monitoring tools, in addition to the integrated VISUALVM and Jconsole, there are JPS, Jstack, Jmap, Jhat, Jstat and other small tools, this blog hope to play a useful, Let's start to understand the common tools for tuning JVM performance.In real-world enter

When using JMX to monitor service container environment data, you need to use each parameter query name, the following lists the monitoring code under each container and the configuration of the query parameter name:
Java Implementation Example:
Import Javax.management.MBeanServer;
