In the performance testing process, it is of great significance to monitor host resources. On the one hand, during the test, you can determine whether the pressurization is successful and whether the system can withstand the current pressure to ensure system security. On the other hand, after the test, you can sort the monitoring data, it can provide data support for performance analysis, problem discovery, and bottleneck search. This article will int

Erlang supports monitor and link two monitoring processes so that all processes can be connected as a whole. When a process exits with an error, the monitoring process receives a message notification that the process exits. With these features, it is not difficult to build a simple, robust system using Erlang. In the previous article, we analyzed the usage of two methods, and analyzed the implementation of
The development of wireless network technology leads to the maturity of wireless video technology. For the digital information age, the perfect combination of digital video monitoring and wireless network technology will certainly produce more powerful technologies. Video Monitoring is an intuitive and convenient way to record detailed information and provides real-time
With the increasing popularity of multicore CPUs, more and more Java applications use multi-threaded parallel computing to give full play to the performance of the entire system. The use of multithreading also poses a huge challenge for application developers, and improper use of multithreading can lead to thread deadlock or resource contention, leading to system paralysis. Therefore, a run-time thread monitoring tool is required to help developers di
Oracle metric index usageOracle provides a monitoring index method to determine whether an index is used. If indexes are not used, you can delete them to reduce unnecessary statement overhead. Because a large number of unnecessary indexes on a table may reduce the performance of DML statements and put pressure on database performance. Therefore, in the production environment, you can regularly monitor and analyze the use of database indexes based on b
