I recently used Alibaba's Dubbo [BaiduProgramAfter a lot of optimization work, the jvisualvm in JDK did a lot of work in this process, but it also gave me some misunderstanding. Let's talk about its merits: First, you can help me monitor the number of threads and promptly discover threads that are not normally terminated. Because Dubbo is configured with a 800 thread pool, the number of daemon threads in my current active thread is 826, and the to

cumulative number of consecutive inaccessible to reach 5 times after the alarm message triggered. How to use:The script needs to be followed by two parameters: the first parameter is the URL of the monitoring site, the second parameter is the delay time (optional, in seconds, it is recommended to add when monitoring multiple sites), add this script to the operating system crontab, set the operating frequency according to the demand, Recommended 2 minutes at a time. If there are multiple sites

Comment: 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 a real-time tra

Use SNMP and Cacti to monitor Linux servers SNMP (Simple Network Management Protocol) is used to collect internal data, such as load, disk status, and bandwidth. Network monitoring tools such as Cacti use this data to generate icons for monitoring purposes. In a typical Cacti and SNMP deployment, one or more SNMP-enabled devices and an independent monitoring serv

Therefore, in terms of network management, it is necessary to understand the traffic status of our hosts and limit or increase bandwidth based on traffic.We can download the MRTG software from the http://www.mrtg.org. Go to http://www.stat.ee.ethz.ch/mrtg/to get the output result of the mrtgtraffic monitoring chart.MRTG is written in Perl and uses zlib, Gd, and PNG functions (zlib is used to compress charts and GD is used to draw charts ). Servers already contain the following software: P

Use Nmon to monitor Linux system performance, nmonlinux Nmon is a computer performance system monitoring tool developed for AIX and Linux systems by IBM employee Nigel Griffin iths. Nmon can display operating system statistics on the screen or store them in a data file to help you understand the usage of computer resources, adjust the direction and system bottlenecks. This system Benchmark Testing Tool only

In two or more SQL server processes, a deadlock occurs when each process locks the resources that other processes attempt to lock. For example,The process process1 holds one exclusive lock (x) for Table1, and process1 requests one exclusive lock (x) for Table2 ),The process process2 holds one exclusive lock (x) for Table2, and process2 requests one exclusive lock (x) for Table1) In this case, a deadlock occurs. Unless an external process is disconnected, the two transactions in the deadlock will

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,

The system. Io namespace in. NET Framework includes the filesystemwatcher class. This class provides the ability to monitor the directory or file of a job. This function is useful if your application needs to know when a new file is added to a specified directory or when the file is deleted. To use filesystemwatcher, you must first create an instance of the class. Private dirwatcher as new system. Io. file
