Experts answer: This seems to be obtained by running vmstat it, here are some parameters reference. LZ can they understand what vmstat are used to check real-time Look at memory usage, reflecting the situation intuitive than top. If used directly, the current situation can only get the best collection with a time interval in which T vmstatT marked with a specific time, in seconds, for example: vmstat5 form for each collected once every 5 seconds. so that refresh When comparing the system will be able to see that the columns are not normal procs: r **; in the run queue waiting to process the number of b **; the number of processes waiting for io w **; can enter the run queue, but were replaced process memoyswap **; currently available swap memory (k Indicated) free **; free memory (k that) pagesre - "Recycling the pages mf -" non-serious error page pi - "to enter the page number (k that) po -" the page number (k said ) fr - "the number of free pages (k that) de -" provided Front page read misses in the number of sr - "pages scanned by clock algorithm disk shows the disk operations per second. s said scsi disk, disk number 0 fault shows the number of interrupts per second, in - "device interrupts sy -" system outage cy - "cpu cpu swap That cpu's use of state cs - "user process time sy -" the system time used by the process id - "cpu idle time in which: If you r always greater than 4, and id always less than 40, said the cpu's load is heavy.
