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
