handles currently opened by each thread in this process. The increase in the handle count in a specific process may be a symptom of a handle leakage error process, which may cause performance problems on the server. This problem may not occur, but it is very important to monitor it for a period of time to determine whether a handle leakage occurs. Process Thread Count Number of active threads in the process. A command is a basic

There is also a need to use a CAE software to call external programs, but after calling the external program through this CAE software, because this external program has parameters, the call method is written in the Bat file, the CAE software calls the Bat. Therefore, the CAE software cannot monitor the called program, and the called program is still running. The preparation is not complete, so the next pro

Problem: the significance of writing this tool is that I am running a program that needs to be executed for a long time, such as a single-thread crawler. In the case of network interruptions or website packet loss, the program will throw socketexception and sockettimeoutexception. The program will be interrupted. (This is just a hypothesis) Solution: Java does not monitor windows processes like C # (this is

JProfiler is a well-known software used for monitoring and analysis of java systems. It has powerful functions and can monitor common java applications, applets, java web start, and application server. In addition to monitoring local programs, you can also monitor applications running on remote servers. This article takes JBoss as an example to briefly introduce

Use the top command to dynamically monitor the memory usage of programs with very short running times Solution: Top-d 0.01-N2000-B | grep lzma -D specifies the interval at which top data is collected. The value is 0.01 seconds. -N indicates the total number of statistics. Set this parameter to 2000 to ensure that the top node does not end the statistics during the program
