value is less than 5m, SQL Server may have a performance bottleneck due to lack of memory. 4.Physical Disk:% Disk Time This counter records how busy the disk is (the entire disk array or the physical disk is busy). Theoretically this value should be less than 55%, if it lasts more than 55%, that indicates that there may be an IO bottleneck on this server. If only occasionally appear several times, that does not need to worry, but can correspond to fi

When the system's physical memory is insufficient, a portion of the physical memory needs to be released for use by the currently running program. The allocation of Swap space is important, but the performance monitoring during system operation is more valuable. Through performance monitoring tools, you can check the

Linux provides a very good file Virtual System (/proc) to monitor system performance. The/proc file virtual system is a mechanism used by the kernel and kernel module to send information to processes. It exists in the memory instead of the hard disk. The main functions of the/proc file virtual system include process information, system information, CPU information, load information, and system memory information. 1.
