Php code for obtaining CPU usage

Share a few php code to get the cpu usage in the current system. if you need it, give it a reference. In php, you can use getrusage () to obtain CPU usage. this method is only applicable to linux systems. Example: 0 [ru_inblock] => 0 [ru_msgsnd] => 2 [ru_msgrcv] => 3 [ru_maxrss] => 12692 [ru_ixrss] => 764 [ru_idrss] => 3864 [ru_minflt] => 94 [ru_majflt] => 0 [ru_nsignals] => 1 [ru_nvcsw] => 67 [ru_nivcsw] => 4 [ru_nswap] => 0 [signature] => 0 [signature [ru_utime. TV _sec] => 0 [ru_stime. TV _usec] => 6269 [ru_stime. TV _sec] => 0) */ Explanation: ru_oublock: block output operation ru_inblock: block input operation ru_msgsnd: sent messageru_msgrcv: received messageru_maxrss: maximum resident set size small ru_ixrss: all shared memory size ru_idrss: all non-shared memory size ru_minflt: page recycling ru_majflt: Page failure ru_nsignals: Received signal ru_nvcsw: active context switching ru_nivcsw: passive context switching ru_nswap: Swap Zone duration: User state Time (microseconds) ru_utime. TV _sec: User State time (seconds) ru_stime. TV _usec: System Kernel time (microseconds) ru_stime. TV _sec: System Kernel time? (Seconds) sometimes you need to check how much CPU the script consumes. you need to check the values of "user-mode time" and "system kernel time. The second and microsecond sections are provided separately. you can divide the microsecond value by 1 million and add it to the second value to obtain the number of seconds with the decimal part. Example: Sleep does not occupy the system time. for example: The running of the above code consumes about 14 seconds of CPU time, and almost all of them are user time, because there is no system call. The system time is the time when the CPU spends executing kernel commands on system calls. Example: The above example shows a higher level of cpu consumption.
