several ways to get fps under Android article refers to the Gamebench tool, which not only obtains FPS, but also obtains system state information such as CPU and memory occupancy rate. Its limitations are also obvious, and the monitoring object needs to be re-selected when switching applications. In addition, one months and 30 minutes of trial time, even if the application of several accounts is not enough. To facilitate development and

Sysstat is a handy tool with a multitude of system resource monitoring tools for monitoring system performance and usage. A significant portion of the tools we use on a daily basis are from the Sysstat Toolkit. It also provides a collection plan that uses CRON expressions to develop performance and activity data.The fo

Linux system performance monitoring common commands Blog Categories:Technical methods First, Linux server performance concerns 1) CPU -> load: The sum of statistics that represents the tasks that the CPU is processing and waiting to process over a period of time, simple to understand the ratio of the number of threads being processed by the CPU to the number of

This article focuses on performance performance monitoring on Linux (CentOS). 1. Monitor CPU Usage--uptime The command will print out how long the current time system has been running. Average system load of logged on users The load here is per unit of time, the CPU waits in the queue, evaluates how many processes are waiting, the more processes
